Most significantly of all, it shrinks the volume of the prefrontal cortex and the hippocampus.
Take the prefrontal cortex, an area that plays a key role in levelheaded decision making and long-term goals.
Repeated administration of Yokukansan inhibits DOI-induced head-twitch response and decreases expression of 5-hydroxytryptamine (5-HT)2A receptors in the prefrontal cortex.

The prefrontal cortex enables us to plan, to innovate, to solve complex problems, to think abstract thoughts, to have visionary ideas.
In particular, the prefrontal cortex reaches out to guide other parts of the brain, including the parts that govern motivation and emotion.
Alcohol handicaps the prefrontal cortex, our reasoning command and control center that would normally constrain someone from lashing out against another person.

The prefrontal cortex has enabled us to have a number of advanced behaviors, including social behavior, tool making, language, and higher-level consciousness.
The prefrontal cortex, that's the last area of the brain to develop.
"It temporarily impairs the prefrontal cortex, the smarty-pants part of the brain that allows you to think clearly and rein inimpulsivity, " Peeke says.
Perhaps for similar reasons, the control system of the brain, which includes areas like the left lateral prefrontal cortex, gets particularly good press.

While the participants were doing this task, the scientists either disrupted their left prefrontal cortex with tDCS or used a sham control procedure.

Patients who responded to medication registered a decrease in prefrontal cortex activity, while those who responded to the placebo registered an increase in activity.
Scans revealed a distinct lack of activation in the ventral prefrontal cortex the brain region that helps to regulate our emotions and control our impulses.
Instead, a region called the parietal lobes, also part of the prefrontal cortex and usually associated with arithmetic performance - was brought into play.
Murderers, for instance, tend to have poorer functioning in the prefrontal cortex the "guardian angel" that keeps the brakes on impulsive, disinhibited behavior and volatile emotions.
This part of the brain is most evolved in human beings, and the area of it we are most concerned with is the prefrontal cortex.
More recent research suggests that the same thing happens in the brain region called the prefrontal cortex, which is crucial for decision-making and attention, he said.
The brains of lying subjects light up in particular places notably the anterior cingulate gyrus and left prefrontal cortex in ways that they do not in the honest.
The scientists used an EEG (electroencephalogram) to measure electrical activity in an area of the brain called the prefrontal cortex, which is involved in judgment and motivation.
Those inhaling the stress sweat had a heightened brain response measured by prefrontal cortex response using an EEG -when looking at faces of all expressions, not just the threatening ones.
When the right prefrontal cortex gets jumpy, it indicates, in this experiment, instinctive revulsion to an obnoxious, tongue-wagging character who pops up in a commercial for Carling beer.
An activity spike in the left prefrontal cortex--an "approach" response to the image of a Kit Kat chocolate bar--would suggest the subject is attracted to the brand image or message.
It's as true to say that our experience of controlling our impulses make the prefrontal cortex develop as it is to say that prefrontal development makes us better at controlling our impulses.
The very talented author of these articles (full disclosure, a friend) is also on this Web-stored NPR show, hinting at his future pieces concerning electronic life and the development of the prefrontal cortex.
Brain-imaging studies have demonstrated that when people are asked to imagine the future as they recall past experiences, many of the same regions of the brain the hippocampus and the medial prefrontal cortex show increased activity.
WSJ: Memory: Research Finds Links Between Recall, Future Planning
Justine Meaux, a neuroscientist at the privately held BrightHouse Institute for Thought Sciences in Atlanta, says the medial prefrontal cortex is active when people behold images of things to which they are extremely attached.
