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.
Stress also causes the release of chemicals that impair the function of the prefrontal cortex, home of higher level thinking.
Some "control" parts of the prefrontal cortex shut down, deactivated, during improvisation but not when the musicians played a memorized score.

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.
Instead, a region called the parietal lobes, also part of the prefrontal cortex and usually associated with arithmetic performance - was brought into play.
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 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.
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.
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.
In the study, he and colleagues focused on an area of the brain called the left dorsolateral prefrontal cortex (DLPFC), which has been strongly implicated in our ability to play with numbers in our heads.
FORBES: Electrical Stimulation Might Improve The Brain's Capacity For Math
Once they had shown that the habit was fully ingrained, the researchers wanted to see if they could break it by interfering with a part of the prefrontal cortex known as the infralimbic (IL) cortex.
FORBES: Could We One Day Switch Off Bad Habits in Our Brains?
Scanning their brains using functional magnetic resonance imaging, the scientists found that a region involved in language processing - the temporal lobe, part of the prefrontal cortex - was activated during verbal learning in rested patients.
Still, the foc.us is one of a few tDCS headsets designed for the consumer market and can, the inventor Michael Oxley claims, improve your working or short-term memory when the electrodes are placed on your prefrontal cortex.
By measuring relative degrees of activation in the parietal lobe, an area involved in integrating visual images, and in the prefrontal cortex, where decision making takes place, Berns says, he could determine that the group changed what the reporter perceived.
