The researchers used repetitive transcranial magnetic stimulation (rTMS) on a specific area of the dorsolateral prefrontal
cortex to briefly alter activity in this brain region and consequently change the amount of punishment a person doled out.
A separate group of rats received optogenetic stimulation of a different brain region, the prelimbic prefrontal
The blunted prefrontal
cortex response to fenfluramine release of serotonin likely underlies differences in intent and impulsivity that are proportional to the seriousness of suicidal acts.
Current dogma, however, is that restoring balance between the activity in left and right prefrontal
cortices is more important than absolute activity in either side.
SPECT imaging shows increased or decreased activity in the temporal lobes and decreased prefrontal
They again found a response in the right prefrontal
cortex that only occurred for the first signal in a series.
PTSD emerged in only 7 of 40 vets with ventromedial prefrontal
cortex damage, conflicting with earlier evidence that inactivity in this area promotes PTSD.
cortex--the brain's "emergency brake," or center for judgment and self-control--is one such area.
As a young woman, Williams was schizophrenic and she underwent a prefrontal
lobotomy and was institutionalized for the rest of her life.
Researchers know that a number of brain structures, including the prefrontal
cortex, which is involved in language processing and memory, are involved in humor appreciation.
The researchers were then able to compare the 12 areas in the human brain region with the organization of the monkey prefrontal
The researchers found that parts of the prefrontal
cortex take over when the hippocampus, the brain's key center of learning and memory formation, is disabled.
