New work by researchers at Vanderbilt University and Harvard University confirms that a specific area of the brain, the dorsolateral prefrontal
cortex, is crucial to punishment decisions.
Participants who went on a 90-minute walk through a natural environment reported lower levels of rumination and showed reduced neural activity in the subgenual prefrontal
cortex, an area of the brain linked to risk for mental illness, compared with those who walked through an urban environment.
Its effects on depression and anxiety might be attributable to activation of a brain region known as the infralimbic prefrontal
cortex, a study published recently online suggested.
Lim Lee Wei from Sunway University, Malaysia, as co-lead authors, discovered that electrical stimulation into the brain via Deep Brain Stimulation (DBS) targeting the prefrontal
cortex, treats symptoms of depression most effectively.
PET scans and a fenfluramine challenge showed that the high-lethality individuals appear to have localized prefrontal
cortex hypofunction and impaired serotonergic responsivity.
The bit of the brain that shows more activity when he says, `It only happened the one time and she doesn't mean a thing to me' is the anterior cingulate gyrus and parts of the prefrontal
and premotor cortex.
Attention-deficit disorder is not a sickness, but a disorder that affects the prefrontal
cortex in the brain.
A year before the premiere, which launched Williams' highly successful career, his family gave Rose's doctors permission to perform a bilateral prefrontal
lobotomy on her.
This might be happening more at the primitive brain structures in the limbic system rather than in the higher-order brain structures such as the prefrontal
cortex," he said.
The differences in volumes in the anterior prefrontal
cortex between lucid dreamers and non-lucid dreamers suggest that lucid dreaming and metacognition are indeed closely connected.
Luan Phan from University of Illinois at Chicago professor of psychiatry and colleagues examined alcohol's effects on connectivity between the amygdala and the prefrontal
cortex during the processing of emotional stimuli - photographs of happy, fearful and angry faces - using functional magnetic resonance imaging, or fMRI.
To locate an aha moment in the brain, a team led by Durstewitz and Jeremy Seamans of the University of British Columbia in Vancouver tracked activity in the prefrontal
cortices of rats that were learning new tasks.
