Have you ever felt paralysed in your sleep? Have you ever felt the presence of an evil on your bed or around you while sleeping? DO NOT PANIC 1. Improve sleep hygiene. 2. Do regular yoga. 3.Avoid sleeping on your back. 4. Relax your mind before sleeping. 5. Seek a specialist for coagnitive behavioural therapy (severe case). .

We don’t think it at the time. We do something that we know it’s probably not in our best interest or good for us, but we do it anyway because we enjoy it. And then we do it again. And again. And again. It doesn’t seem like much in the moment, but little by little we have forged a habit into our psyche. . It doesn’t matter whether it is good or bad, healthy or unhealthy, moral or immoral. Once we have developed a habit, it cannot be erased from our psyche. In fact, scientists say that you could never fully erase a habit once it is burned into our minds. The only way to “break” an old habit is to develop another habit in its place that is laid down over the old one in our neural pathways That more positively affects the pleasure center of our brain. . So, before you consider doing something that you know is not right we’re good for you, consider the extra work you’ll have to do in your life to break that unhealthy old habit. . #Habit #Habits #NeuralScience #Lifestyle #Education #Learning #Success #Productivity #GrowthMindset #Growth #PersonalDevelopment #BrainScience #Quote #Quotes #sdward #happiness #sin #jesus #christianity #newlife #goodhabits #badchoices #badhabits https://www.instagram.com/p/Bp8GS8WgRoR/?utm_source=ig_tumblr_share&igshid=xze7id4chago

How app and web marketers use neural computer science?

Airlines and travel portals hike up the price of the tickets if you look at it just enough number of times, by tracking your cookie data? Now imagine, a shopping mobile app like myntra etc. which basically tracks each and everything you do on your phone. If you look at a piece of clothing enough number of times, there might never be a discount for you. While some other user would be getting a 30% off on the same merchandise! :-)

Does the Brain Have an Emotion Module?

This post is part three of a short series on social psychology, made up of thought papers I wrote for the Affective Science (PSY5430) course at the University of Toronto, Department of Psychology.

This week’s post focuses on the physiological aspect of emotions, mainly the investigation into the neurological configuration of the brain which deals with affect, appropriately called Affective Neuroscience.

Our original understanding of a living organism’s body, especially primates, is the physical configuration of various body parts, and the obvious functions they perform. The heart is clearly made for pumping blood throughout our system. The human legs are meant to keep us upright and give us the ability to move about. The eye’s most obvious function is to convert light into signals our brain can interpret. This organ-function view of the body has been applied to the brain as well, which is the locationst view [Lindquist et al., 2012]. With the advancement in tools, we discovered that the brain is not simply a set of modules, but a network of neurones. The obvious question, then, is whether the brain could be understood as both individual “parts”, analogous to a leg or an eye, as well as a network of connections. This is the argument of whether a brain is modular, a network, or both, which is the constructionist view [Lindquist et al., 2012].

If we consider the constructionist view of the brain, an internal modularity can still exist in both the physiological and functional forms. Functional in the sense that a group of neurones not necessarily spatially close, work together to perform a task. The formation of modules and hubs has been observed in artificial neural networks when various real-life constraints are placed on the communication between nodes [Pan and Sinha, 2007]. This research has found that modules are formed naturally when a cost is placed on the spatial distance (based on edge-counting) between nodes. This is a realistic view of a physical organ which must balance energy consumption and effectiveness.

Consider the amygdala, a physical hub, connecting various external stimuli to parts of the brain. The amygdala is closely related to fear, meaning fear should be correlated with those senses [Janig, 2003]. Its function has to do with quick responses and interpretations, so it makes sense that the amygdala takes the architectural shape of a tightly connected and efficient hub. In contrast to physical hubs, network hubs in the human brain exist to a serve different type of function [van den Heuvel and Sporns, 2013]. They allow for high levels of functional diversity and functional synchronization between cortical regions. Interpreting emotions is a complicated task and its processing has been observed to be divided between a number of regions with multitude of complex connections. For example, the recognition of emotion from facial expressions and prosody are split between the right and left temporal lobes [Berridge, 2003]. Such hubs form early on in brain development. For example the connection between the medial posterior cingulate, frontal and insular regions are already present in the postnatal infant and child brain [van den Heuvel and Sporns, 2013]. Due to the sheer numbers of neurones in the brain and their complex interconnectedness, it may be impractical, if even possible, to try and identify the functions of individual neurones. Instead, its more feasible to identify sub-networks of neurones which function together to achieve a task. It would also be more practical to identify which hubs of neurones largely function as incoming or outgoing points, the so-called sink or source hubs [van den Heuvel and Sporns, 2013]. It may make sense to call a group of neurones a module, based on their spatial proximity, but it should not be viewed as the only architecture the brain has utilized.
