Brain Differences Between Sciences and Humanities

The areas of academic interest (sciences or humanities) and area of study have been known to be associated with a number of factors associated with autistic traits. However, despite the vast amount of literature on the psychological and physiological characteristics associated with faculty membership, brain structural characteristics associated with faculty membership have never been investigated directly. In this study, we used voxel-based morphometry to investigate differences in regional g...

 The Prefontal Cortex

Executive functions take place in the prefrontal cortex of the brain. I love the term that Stanislas Dehaene uses to describe this part of the brain—a global neuronal workspace. The prefrontal cortex is responsible for the ability to exchange information across the high-level areas of the brain, Dehaene says, so that our behavior can be guided by our accumulated knowledge. That’s the beauty and the purpose of executive functions: they enable us to control ourselves, to reflect deeply, and...

 Attentive States of Mind

Whether you think of it as a sin, a temptation, a lazy habit of mind, or a medical condition, the phenomenon begs the same question: why is it so damn hard to pay attention? It’s not necessarily our fault. As neurologist Marcus Raichle learned after decades of looking at the brain, our minds are wired to wander. Wandering is their default. Whenever our thoughts are suspended between specific, discrete, goal-directed activities, the brain reverts to a so-called baseline, “resting” state...

 Challenging Inhibited Behavior in Children

But with the right balance, parents can modify even the most difficult side of their children's temperaments. As an example, consider those 15 percent or so of toddlers who are very inhibited—kids like Andrew, whose right frontal lobe explodes with anxiety whenever he's confronted by new people or a new environment. While many of these children don't change, about 40 percent do lose their extreme timidity by kindergarten. Researchers have observed that these are the youngsters whose parents...
