fMRI Explained: Decoding the Brain’s Visual Circuitry

fMRI is a word often heard in discussions about brain research, psychology, and medical imaging. But what is fMRI exactly? And what makes it such a pioneering instrument for comprehending not just the appearance of the brain but also its functioning?

Functional Magnetic Resonance Imaging, or fMRI for short, is a non-invasive imaging technique that lets researchers and medical professionals view what the brain is doing in real-time. It displays dynamic activity by showing how various brain areas “light up” in reaction to ideas, pictures, emotions, and actions. fMRI goes beyond the static anatomical photographs of a conventional MRI. Knowledge of fMRI is not limited to researchers. fMRI is an incredible step towards understanding the inner workings of the human mind, and it can transform our understanding of mental health and memory.

How fMRI Works: Brain Activity via Blood Flow

A basic yet potent principle is at the heart of all fMRI systems: the brain requires more oxygen when a portion of it is engaged. In response, the body increases blood flow to the affected region. fMRI uses a technique known as BOLD (Blood Oxygen Level Dependent) opposition to monitor these minute variations in blood oxygen levels.

fMRI provides a movie-like perspective revealing patterns of cerebral activity throughout time, in contrast to standard brain imaging, which provides a still image. Your brain activity may be examined when solving a math problem, gazing at a picture, or experiencing anxiety.

Using fMRI to Explore the Brain’s Visual World

fMRI visual system investigation is among the most intriguing uses of this technology. The brain uses a complicated network of regions to interpret information when perceiving a face, colour, or moving items.

Scientists can see how the brain reacts to various visual inputs through fMRI scans of the visual system. The scans cover anything from spotting an object’s edge to identifying a well-known face. The visual centres of our brains nevertheless function in strikingly comparable ways to real-world sight, even when we visualise scenes (such as a sunset or a loved one’s smile). fMRI is brilliant because it allows us to monitor perception and imagination.

The Department of Biotechnology’s National Brain Research Centre has developed SWADESH, India’s first large-scale multimodal neuroimaging database tailored for the Indian population.

The Workings of an fMRI System in the Lab

A complete fMRI system comprises more than simply the scanner. It usually consists of:

A strong magnet (often 3 Tesla or greater)

Radiofrequency coils for collecting brain impulses

Data processing software for BOLD contrast

fMRI monitor used in a stimulus delivery system

The function of the fMRI monitor is crucial. It displays pictures, movies, audio, or text to participants during scanning. For example, a participant may see a sequence of emotive facial expressions or read words on a screen while the scanner records which brain areas are active. Even little timing differences between the monitor presentation and capture might distort findings. Therefore, engineers design fMRI monitors for ultra-high accuracy and MRI safety.

The Prospects of fMRI: More Intelligent, Quicker, and Tailored

fMRI technology is rapidly advancing. We observe improvements in:

Time resolution: Recording brain activity on increasingly more precise time scales

Spatial accuracy: Accurately identifying activity down to the minutest cortical layers in space

Giving patients real-time feedback: Using neurofeedback to teach them how to control their brain states

AI integration: Using machine learning to decipher ideas, intents, or even forecast behaviour from fMRI data.

Consider a scenario in which a neurologist can use fMRI to diagnose Alzheimer’s disease decades before symptoms appear, or a therapist can monitor a patient’s emotional control in real time. The future isn’t as far as it previously appeared.

fMRI in the Real World: Practical and Clinical Uses

Most people think of fMRI as being used in high-tech labs or for academic research, yet its practical uses are expanding rapidly, particularly in clinical settings.

Doctors currently utilise fMRI devices for:

Pre-operatively map the brain function of patients with epilepsy or tumours to assist neurosurgeons in avoiding key regions while doing surgery.

Evaluate brain damage following a stroke or trauma to inform recovery strategies.

Track the healing process of brain injury patients by observing changes in their functional abilities.

Researchers use fMRI in forensic and judicial settings to investigate memory, dishonesty, and truth-telling-though the method remains experimental and contentious. fMRI can become a personal health tool for anybody interested in brain function. Experts may use it to track cognitive ageing, monitor mental well-being, or enhance learning and performance.

A study by IIT Delhi using fMRI found significant changes in brain functional connectivity during Yoga Nidra practice, highlighting its impact on emotion regulation and awareness.

What’s Next for fMRI: Looking Deeper Into Ourselves

In many respects, fMRI is among the most audacious scientific advances made in attempting to address the perennial query: Who are we? We discover more about the formation of ideas, the formation of memories, the flow of emotions, and our connection to the outside world. We start to realise the true complexity of our exquisitely designed brains.

Therefore, fMRI is your invitation to pursue that journey- to go past the obvious and genuinely understand what is going on within the mind, whether you are a neuroscience student, a patient seeking a diagnosis, or just someone interested in the inner workings of the brain. And as technology advances, so will our understanding not only of the brain but of the entire human experience.

Conclusion

fMRI has completely changed our understanding of the brain by providing real-time information on our thoughts, emotions, and perceptions of the outside world. It has proven to be an effective tool in therapeutic and scientific contexts by establishing a connection between brain activity, behaviour, and emotion. By creating new avenues for the diagnosis, treatment, and eventual comprehension of the intricacies of the human mind, its contributions will continue to influence neuroscience and medicine in the future.

The ‘Pain of Paying’: How Spending Feels and Why Tracking Helps

In today’s digital economy, spending money has become easier than ever. With one-click purchases, contactless cards, and auto-renewing subscriptions, we can make transactions in seconds — and forget about them just as quickly.

But beneath this convenience lies a powerful psychological force: the pain of paying.

This emotional response plays a surprising role in shaping our financial habits, and if you understand how it works, you can use it to your advantage — especially with the help of money-tracking tools like Mevolve.

In this blog, we’ll explore:

What the pain of paying is and how it works in the brain

How modern spending dulls that pain — and why that’s risky

How tracking expenses revives financial awareness

How Mevolve’s Money Tracker helps you take control

Let’s dive in.

What Is the Pain of Paying?

The “pain of paying” is a term from behavioral economics that describes the negative feeling we experience when we part with money. It’s not a metaphor — it’s real emotional discomfort.

The term was popularized by MIT professor Dr. Drazen Prelec, whose research found that our brains process spending similarly to physical pain.

When you pay with cash, your brain registers the outflow in a tangible, almost painful way. This pain serves a purpose: it makes you think twice before spending.

What Happens in the Brain When We Spend?

Neuroscience research, including fMRI scans, shows that:

The insula, a region linked to pain and emotion, activates when we anticipate or make a purchase.

The nucleus accumbens, associated with pleasure, lights up when we desire something.

This creates a mental tug-of-war:

“I want it” vs. “Ouch, that’s expensive!”

This is what makes financial decisions so emotional — not just logical.

How Technology Has Numbed the Pain

Here’s the problem: modern payment systems have muted our pain of paying.

Why?

Credit cards separate the action of buying from the act of paying (you’ll “feel it” later).

Digital wallets and tap-to-pay make payments so fast, they feel weightless.

Subscriptions and autopay remove visibility — you’re not actively involved in the transaction.

This phenomenon is called decoupling — the disconnection between consumption and payment. And it reduces spending resistance, making us more likely to overbuy.

According to a study by MIT and Carnegie Mellon, people spend up to 100% more when using cards instead of cash.

Why the Pain of Paying Is Good (When Controlled)

You might think pain is a bad thing. But in finance, it’s protective.

It’s your brain’s natural alert system saying:

“Are you sure this is worth it?”

“Is this aligned with your goals?”

“Will you regret this tomorrow?”

When dulled or bypassed, this system fails to prevent impulsive or emotional spending.

That’s where expense tracking comes in.

How Expense Tracking Brings Awareness Back

Tracking expenses manually or with an app like Mevolve brings back the awareness we lose in digital payments. Here’s how:

1. It Creates Conscious Reflection

Every time you log an expense, you’re forced to think about it. This moment of reflection reactivates the emotional circuits your payment method skipped.

2. It Makes Spending Visual

When your expenses are visualized — by date, category, or chart — your brain processes your behavior more clearly. You begin to see patterns, not just feel them.

3. It Builds Self-Control Over Time

Studies show that self-monitoring increases financial discipline. Tracking allows you to course-correct before things spiral out of control.

How Mevolve’s Money Tracker Supports Financial Awareness

The Mevolve Money Tracker is built to bring clarity, control, and calm to your finances — without complexity.

Here’s how it helps:

Instant Logging

Add expenses or income in seconds. No clutter, no confusion.

Visual Reports

View your spending by date, category, or tag — using monthly calendars or clean charts.

Tagging

Label transactions for groceries, subscriptions, travel, or custom categories. Discover hidden spending trends.

When Tracking Becomes a Habit, You Spend Smarter

Most people don’t overspend because they lack discipline — they overspend because they lack visibility.

With consistent tracking:

You reconnect with your emotional money triggers

You make more intentional choices

You save more — without cutting joy

It’s not about being strict. It’s about being smart.

Conclusion

The pain of paying is a natural, intelligent part of how your brain protects you. But modern life is designed to numb it.

By tracking your expenses, you restore your brain’s ability to feel, reflect, and decide — all while building long-term financial habits.

With Mevolve, you’re not budgeting in spreadsheets. You’re building a relationship with money that feels human — clear, calm, and under control.

Don’t just spend. Spend with awareness.

How the Brain Works: A Beginner’s Guide to Neuroscience | Lahouaria Hadri, Mount Sinai

The human brain is the most complex structure in the known universe. It allows us to think, feel, remember, move, and even question our own existence. Neuroscience—the study of the nervous system, including the brain—helps us understand what makes us human, how our bodies function, and how we perceive the world. From memory and emotion to consciousness and behavior, neuroscience explores the mechanics behind what we experience every day.

What is Neuroscience?

At its core, neuroscience is the scientific study of the nervous system, which includes the brain, spinal cord, and a vast network of nerves that branch throughout the body. It combines biology, chemistry, physics, and even computer science to explore how neurons (nerve cells) communicate and how these interactions produce everything from motor skills to moods.

Neuroscience isn’t just academic—it plays a vital role in understanding and treating disorders like Alzheimer’s disease, Parkinson’s disease, depression, anxiety, stroke, and many more.

The Building Blocks: Neurons and Neurotransmitters

The brain contains around 86 billion neurons, each connected to thousands of others, forming a dense communication network. These neurons don’t physically touch; instead, they communicate via tiny chemical messengers called neurotransmitters. Some key neurotransmitters include:

Dopamine – involved in reward, motivation, and pleasure.

Serotonin – regulates mood, appetite, and sleep.

Acetylcholine – essential for learning and memory.

GABA (gamma-aminobutyric acid) – reduces neural activity to prevent overstimulation.

The space between neurons where this communication happens is called a synapse. When a neuron “fires,” it sends an electrical signal down its axon, releasing neurotransmitters into the synapse, which are then absorbed by the receiving neuron’s receptors. This process forms the foundation of every thought, feeling, and action.

Brain Anatomy 101

The brain is divided into several regions, each with specialized functions:

Cerebrum: The largest part of the brain, responsible for reasoning, emotions, memory, and voluntary movement. It’s divided into four lobes:

Frontal lobe – decision-making, planning, personality.

Parietal lobe – sensory information like touch and spatial awareness.

Occipital lobe – visual processing.

Temporal lobe – auditory processing and memory.

Cerebellum: Coordinates balance, posture, and fine motor skills.

Brainstem: Connects the brain to the spinal cord and regulates vital functions like heartbeat and breathing.

Limbic system: Often called the “emotional brain,” it includes structures like:

Amygdala – processes emotions such as fear and pleasure.

Hippocampus – vital for forming new memories.

Hypothalamus – controls hunger, thirst, sleep, and hormones.

How Does Memory Work?

Memory isn’t like a video camera; it’s more like a jigsaw puzzle. Neuroscientists divide memory into three main stages:

Encoding – taking in information.

Storage – maintaining the information over time.

Retrieval – accessing the information when needed.

The hippocampus plays a crucial role in forming and organizing new memories. Over time, these memories are consolidated and stored in various parts of the cortex. Different types of memory (short-term, long-term, procedural, emotional) involve different neural circuits.

Consciousness and the Mind

One of the most profound questions neuroscience seeks to answer is: What is consciousness? How do physical neurons give rise to the subjective experience of being alive?

While we don’t fully understand consciousness, research has identified certain brain regions, like the prefrontal cortex and thalamus, as essential for self-awareness and higher-order thinking. Technologies like functional MRI (fMRI) and EEG allow researchers to study brain activity in real-time, offering clues into what happens in the brain when we make decisions, dream, or focus.

Brain Plasticity: The Brain That Adapts

The brain is not a fixed organ; it changes throughout life. This ability, known as neuroplasticity, allows the brain to reorganize itself by forming new neural connections. It’s how we learn, recover from injuries, or adapt to new environments.

For example, if someone suffers a stroke and loses the ability to speak, with therapy and time, other areas of the brain may take over those functions. Neuroplasticity is also why habits, both good and bad, can become deeply ingrained.

When the Brain Gets Sick

Understanding how the brain works also helps us recognize when it doesn’t. Disorders of the brain and nervous system can profoundly impact quality of life.

Alzheimer’s disease involves the buildup of toxic proteins that destroy neurons, particularly in memory-related areas.

Parkinson’s disease results from the loss of dopamine-producing neurons, affecting movement and coordination.

Depression and anxiety��are linked to imbalances in neurotransmitters and disrupted neural circuits.

Ongoing research is shedding light on the causes of these disorders and improving treatments. Innovations like brain-computer interfaces, deep brain stimulation, and gene therapy offer hope for future cures.

The Future of Neuroscience

Neuroscience is advancing rapidly, thanks in part to artificial intelligence, brain imaging technologies, and interdisciplinary collaboration. Some exciting developments include:

Brain-machine interfaces: Devices like Elon Musk’s Neuralink aim to connect the brain directly to computers, potentially restoring function to paralyzed patients or enhancing cognition.

Connectomics: Mapping all the connections in the brain (the “connectome”) to better understand how different areas interact.

Personalized medicine: Using genetic and neural data to create customized treatments for brain disorders.

As our understanding grows, so does our potential to unlock the brain’s mysteries, improve mental health, and enhance human capabilities.

Why Neuroscience Matters

Neuroscience doesn’t just belong in labs or hospitals—it affects our daily lives. It informs education, mental health, technology, and even how we relate to one another. By understanding how the brain works, we can improve learning methods, develop better treatments for disorders, and make more informed decisions about technology, ethics, and society.

Final Thoughts

The brain is astonishing—not just because of its power, but because it is the very thing that lets us understand it. Neuroscience is still young, but each discovery brings us closer to understanding who we are and how we can thrive.

Whether you’re curious about how memory works, passionate about mental health, or excited about futuristic brain tech, neuroscience has something for everyone. It’s a journey into the very center of what makes us human—and we’re only just getting started.

MRI Scan Cost in India

Magnetic Resonance Imaging (MRI) is a sophisticated, non-invasive diagnostic tool used by doctors to get detailed images of the internal organs, tissues, and skeletal system. It plays a crucial role in diagnosing a wide range of medical conditions, from brain tumors and spinal cord injuries to joint problems and organ diseases. While MRI scans are widely available across India, their cost can vary significantly depending on several factors. Understanding these factors can help patients make informed decisions when choosing where to get an MRI done.

What is an MRI Scan?

MRI uses powerful magnets, radio waves, and a computer to produce detailed images of the inside of the body. Unlike CT scans or X-rays, MRI does not use ionizing radiation, making it a safer option for many patients, including pregnant women in certain conditions.

It is commonly prescribed to investigate:

Brain and spinal cord abnormalities

Joint and musculoskeletal issues

Tumors and cancers

Liver and abdominal diseases

Heart and vascular conditions

Types of MRI Scans

The cost of an MRI scan depends largely on the type of MRI being conducted. Some common types include:

Brain MRI

Spine MRI (cervical, thoracic, lumbar)

Knee, shoulder, or other joint MRIs

Whole-body MRI

Contrast MRI (with dye for enhanced imaging)

Functional MRI (fMRI) for brain activity

MR Angiography (for blood vessels)

Each type requires different levels of expertise, imaging duration, and equipment usage, which contributes to variation in costs.

MRI Scan Cost in India: General Price Range

The cost of an MRI scan in India ranges from ₹2,000 to ₹25,000, depending on the region, type of scan, and healthcare facility.

Prices in metro cities like Delhi, Mumbai, Bengaluru, Hyderabad, and Chennai tend to be slightly higher due to advanced infrastructure and demand, while smaller cities and towns may offer more economical options.

Factors Affecting MRI Cost

Several elements influence how much you pay for an MRI scan:

Type of MRI Machine:

1.5 Tesla vs. 3 Tesla Machines: 3T machines provide higher resolution images and are generally more expensive.

Open vs. Closed MRI: Open MRI machines are more comfortable for claustrophobic patients but may cost more due to their specialized design.

With or Without Contrast: MRIs done with a contrast agent (usually gadolinium) enhance the image quality and are more expensive due to the added material and monitoring required.

Hospital or Diagnostic Center: Government hospitals and diagnostic centers often offer scans at subsidized rates, while private hospitals and imaging chains may charge a premium for faster service and advanced equipment.

City or Location: Urban areas with advanced medical infrastructure tend to have higher prices compared to semi-urban or rural areas.

Health Insurance: If covered under a medical insurance plan, the cost of MRI scans may be partially or fully reimbursed depending on the policy and reason for the scan.

Ways to Save on MRI Costs

Brain imaging studies have investigated the neural mechanisms of recovery in adults following acquired disorders and childhood developmental disorders. However, there are few to no studies that investigate the neural systems that underlie adult rehabilitation of neural-ingrained learning disorder (i.e. those from birth) despite their high incidence. In this study, researchers identified the differences in brain activity during a phonological manipulation task before and after a behavioral intervention in adults who had developmental dyslexia. Phonologically targeted training resulted in improvements in reading in the instructed participants as compared to the dyslexics who received no instruction, and fMRI showed concordant increases in activation in the bilateral parietal and right perisylvian cortices. Authors concluded that behavioral plasticity in adult developmental dyslexia involves two neural mechanisms (or regions in the brain) 24 participants were used. A sublecxical sound deletion task was employed where researchers tested for phonological processing. They tested 19 dyslexic patients who did not receive reading instruction with 19 dyslexic patients who had received instruction (112 hours of structured multi-sensory phonological intervention) and using FMRI identified regions of the brain that were activated during the study. . . Adults who received instruction benefited significantly in their phonological processing skills as compared to those who had not received instruction. This improved understanding of the phonological characteristics of language led, in turn, to improving other aspects of reading ability such as nonword decoding and oral paragraph reading. The study is helpful in that it provides enhanced understanding of the neural characteristics of adults with dyslexia as well as how to structure interventions that can improve their neural plasticity.

Researchers here compared pediatric brain development during reading tasks to those of adults using fMRI. Their task involved an implicit word-processing task that required detection of a visual feature (tall letters) within both words and matched false font strings. Reading was done using eye-motion. Researchers studied an unrelated amount of participants whose ages ranged from 6 to 22 years and found that learning to read is associated with two patterns of change in brain activity: increased activity in the left-hemisphere middle temporal and inferior frontal gyri and decreased activity in the right inferotemporal cortical areas. Activity in the left-posterior superior temporal sulcus of the youngest readers was associated with the maturation of their phonological processing abilities. These discoveries are relevant to the focus of this assignment's focus in that younger children may indeed have an easier time learning to read than adults. They also found that learning to read was associated with engagement of left inferior frontal and middle temporal cortices as well as disengagement of right inferotemporal cortex It remains to investigate whether neuroplasticity can be strengthened to make up for these natural conditions and whether it can be strengthened using mechanisms that would employ these neural regions.

**Mechanism of Migraine with Aura: Step-by-Step Brain Tissue Changes**

Migraine with aura involves a cascade of neurological events, primarily driven by **cortical spreading depression (CSD)** and subsequent activation of pain pathways. Here’s a breakdown of the process:

---

### **1. Initiation of Cortical Spreading Depression (CSD)**

- **Trigger**: Neuronal hyperexcitability in the cortex (often genetic or due to ion channel dysfunction) leads to abnormal electrical activity.

- **Mechanism**: A sudden surge of neuronal depolarization (excessive firing) begins in a localized brain region, typically the **occipital lobe** (visual cortex).

- **Key Players**:

- **Glutamate**: Excess release of this excitatory neurotransmitter triggers depolarization.

- **Potassium (K⁺) ions**: Leak from neurons, propagating the wave.

---

### **2. Wave of Depolarization Spreads**

- **Process**: The depolarization wave spreads across the cortex at ~3–5 mm/minute, temporarily disrupting normal brain activity.

- **Symptoms**:

- **Visual aura**: Flashing lights, zigzag patterns (scintillations) or blind spots (scotoma) as the wave affects the visual cortex.

- **Sensory aura**: Tingling/numbness (parietal lobe involvement) or speech difficulties (Broca’s area).

---

### **3. Neurotransmitter & Ionic Shifts**

- **Glutamate Surge**: Sustained depolarization increases extracellular glutamate, overstimulating NMDA receptors and causing excitotoxicity.

- **Calcium Influx**: Neuronal calcium overload disrupts mitochondrial function, generating **reactive oxygen species (ROS)** and oxidative stress.

---

### **4. Cerebral Blood Flow Changes**

- **Initial Hyperemia**: Brief increase in blood flow (due to vasodilation) during depolarization.

- **Oligemia**: Prolonged reduced blood flow (vasoconstriction) following the wave, potentially contributing to hypoxia-like symptoms.

- **Imaging**: fMRI studies show a "spreading oligemia" matching the aura’s progression ([*Annals of Neurology*](https://doi.org/10.1002/ana.410280502)).

---

### **5. Trigeminovascular System Activation**

- **Trigeminal Nerve Stimulation**: CSD activates pain-sensitive trigeminal nerve terminals in the meninges (brain’s protective membranes).

- **Inflammatory Mediators**:

- **CGRP (Calcitonin Gene-Related Peptide)**: Released, causing vasodilation and neurogenic inflammation.

- **Substance P**: Enhances pain signaling and sensitizes blood vessels.

---

### **6. Central Sensitization & Pain**

- **Pain Pathways**: Trigeminal signals reach the thalamus and cortex, perceived as throbbing headache (often unilateral).

- **Sensitization**:

- **Allodynia**: Normal touch becomes painful (due to hyperexcitable neurons).

- **Photophobia/Phonophobia**: Brainstem nuclei (e.g., locus coeruleus) amplify sensitivity to light/sound.

---

### **7. Resolution & Postdrome**

- **Recovery**: Neurons repolarize, blood flow normalizes, and inflammatory mediators clear.

- **Postdrome**: Fatigue, cognitive fog, or residual sensitivity due to lingering neurotransmitter imbalances.
