Hobbies like embroidery, cross-stitching, crocheting, and knitting can release neurotransmitters in the brain that promote calmness and happiness. There are nerves in the fingertips that are activated when you press them together that send messages to your brain that calm it down. Apparently, holding a needle (or needles) activates those nerve points 🧵 🧶 🪡

How Exocytosis Works from Cell A to Cell B

When a nerve signal reaches Cell A, calcium (Ca²⁺) enters, causing vesicles with neurotransmitters to move. The vesicles release neurotransmitters into the synaptic cleft (the gap between cells). These neurotransmitters then bind to receptors on Cell B, passing the signal along. After releasing the neurotransmitters, Cell A recycles the vesicles for future use. This process helps neurons communicate quickly and efficiently.

Learning about Neurotransmitters and decided to make this

[ribbitflings]

the absolute fucking letdown when youre excited af about something cool you found that pertains to your interests—thats like a gold mine or candy shop for you—and you try to share it with other people so they can enjoy it too, only to be met with disinterest or feeble attempts at feigning interest

The Fireworks of your Mind

This sparkling video shows the neurotransmitter glutamate being released into synapses.

Glutamate is the most common neurotransmitter in the brain, yet measuring it at synapses (where neurons connect and communicate with each other) can be difficult because synapses are tiny and communicate very, very quickly.

Researchers from the Allen Institute, Janelia Research Campus, UC San Diego, and more developed an indicator for detecting and measuring this important neurotransmitter. This indicator, dubbed iGluSnFR3, is a protein that fluoresces (glows under a special light) when it binds to glutamate.

Not only does it create beautiful videos like this, but it also allows researchers to collect more and better data on how neurons connect and interact across the brain.

As someone used to excess Dopamine because of how random my genetic polymorphism went (met/met), when I decided to lower my thyroid medication because by nature triiodothyronine fosters growth, and I'm in the middle of discovering if I have cancer or not, I didn't consider that despite the huge dosage I am on, lowering the dose would affect neurotransmitters.

And now for the last 48 hours I've lived with the frustration of never enough dopamine to get motivated, always little enough to realise I'm useless and can't do anything about it not even think words (I basically threw myself in accidental ADHD), and I have renewed respect for anyone that lives like this constantly.

How people with ADHD manage to get anything done, let alone be nice to anyone who ever interacts with them, is insane to me. There is literally nothing in their brain chemistry giving them the ability to access "decency" yet they do.

Wow.

Just wow.

"Serotonin, often referred to as the 'feel-good' neurotransmitter, plays a vital role in regulating mood, sleep, appetite, and digestion. Adequate levels of serotonin are associated with an improved mood and a sense of calmness, whereas deficiencies can lead to depression and anxiety. Oxytocin, known as the 'love hormone,' is released during social bonding activities like hugging or teamwork. This hormone enhances trust, empathy, and connectivity, and is essential for managing stress and promoting cardiovascular health. Endorphins, the body's natural painkillers, are produced in response to stress or pain. These help relieve discomfort and boost pleasure, typically felt as a 'runner's high' during intense physical exercise. Dopamine is crucial for the brain's reward system, influencing motivation and satisfaction. It supports essential functions such as movement, attention, and learning, and maintaining balanced dopamine levels is important for overall mental health." Positive Psychology Coaching (LinkedIn)

My levels of serotonine, oxycotine and noradrenaline for you have increased.

And why? My levels have lately decreased in general. And oxycotine? Are you talking about oxycontine, also called oxycodone? You probably meant oxytocin, that's the neuropeptide for social bonding. Meanwhile oxycontine with the switched c and t and added n, that's an opioid drug, which I find much preferable. And am I stressing you out or why is your noradrenaline increasing as well?

Conclusions

Autonomic synucleinopathies involve decreased urinary excretion rates of norepinephrine and dopamine. Since virtually all of urinary dopamine in humans is derived from circulating DOPA, the low rates of urinary norepinephrine and dopamine excretion may reflect dysfunctions in the renal sympathetic noradrenergic system, the DOPA-dopamine autocrine-paracrine system, or both systems.

How Neurons Communicate: Signal Transmission at the Synapse

When a nerve signal reaches the end of a neuron, it cannot jump to the next cell directly. Instead, it triggers the opening of calcium channels, causing neurotransmitters to be released into the synaptic cleft. These neurotransmitters cross the gap and bind to receptors on the next neuron, either activating or blocking a new signal.

“It’s kinda messed up that the more I research into ADHD, the more dangerous stuff I find out I’m at risk for and the more being medicated constantly sounds like the best way to go.”

“Oh wait, I AM medicated at least 80% of the time now. THANKS, SUGARY SWEET STUFF! AND MUSIC! AND EXERCISE! AND FIDGET TOYS!”

“I’m wondering if I can actually switch taking 2-3 Mike and Ike’s in the morning with just fidgeting with my little galaxy cube thing to get me out of bed.” 🤔

I spent the last couple days making neurotransmitter trading cards for AP Psychology, and finally, they are finished…

We were basically allowed to do whatever as long as we have their names, 2 functions, surplus/deficit effects, type, and a representative picture. I—in my poor one piece brainrotted state—immediately went “i should make them transponder snails” and oh my god were these hard??? Like these guys are so simple but theyre so weird and hard to design at the same time????

Anyways. Heres hoping I get an A.
