Neural Hyperactivity: Genius and Deviant Psychology

I don’t feel like synthesizing all this reading into a coherent post at the moment, but I’m tired of looking at it in my drafts folder. I’ll get around to refining these ideas and making my intuitions about this research more explicit, but I’ll publish it in the mean time in the event that anyone feels up to drawing some connections between all this research. Ultimately, I’m interested in the areas of the brain that produce genius. Specifically, I want to explore the overlapping’s of ADHD, depression, and other ‘mental disorders’ with creativity, problem solving, novelty seeking, and, to a greater or lesser extent, intelligence. 

Once again, I apologize if it’s utterly incoherent at the moment, but there is a rhyme to all the erraticism. 

An over active brain has been linked to depression. Rather than decreased activity, researchers have found.

Hyperactivity and Depression

Adhd and Depression: 2.7 times

ADHD and size and grey matter: Reductions in size of prefrontal regions, the executive function relates to abilities to differentiate among conflicting thoughts, determine good and bad, better and best, same and different, future consequences of current activities, working toward a defined goal, prediction of outcomes, expectation based on actions, and social “control” (the ability to suppress urges that, if not suppressed, could lead to socially unacceptable outcomes)

Substantial increases were noted in the volume of gray matter in large areas of the posterior temporal and inferior parietal cortices of children with ADHD, compared with children in the control group. These regions have previously been identified as areas of the brain controlling attention and impulse control.
Grey matter (grey matter includes regions of the brain involved in muscle control, sensory perception such as seeing and hearing, memory, emotions, and speech

Posterior temporal responsible for semantic formation and verbal ability

Inferior parietal cortices: involved in the perception of emotions in facial stimuli,and interpretation of sensory information. The Inferior parietal lobule is concerned with language, mathematical operations, and body image, particularly the supramarginal gyrus and the angular gyrus. The parietal lobe integrates sensory information from different modalities, particularly determining spatial sense and navigation.

Children with ADHD had the slowest rate of cortical thinning.

It receives inputs from the thalamus and the neocortex, and projects to the entorhinal cortex via the cingulum. It is an integral part of the limbic system, which is involved with emotion formation and processing, learning, and memory, and is also important for executive function and respiratory control.

One thought on “Neural Hyperactivity: Genius and Deviant Psychology”

  1. Awesome. I will definitely be adding this to my “collection” of things to hyper-focus on when the time is right. I’ll share if anything particularly interesting arises. Much thanks.
