fron·tal cor·tex

cortext of the frontal lobe of the cerebral hemisphere; originally, the entire cortical expanse anterior to the central sulcus, including the agranular motor and premotor cortex (Brodmann areas 4 and 6), the dysgranular cortex (Brodmann area 8), and the granular frontal (prefrontal) cortex anterior to the latter; now more often refers to the granular frontal (prefrontal) cortex.
Synonym(s): frontal area

fron·tal cor·tex

(frŏn'tăl kōr'teks)
Cortex of the frontal lobe of the cerebral hemisphere.
Synonym(s): frontal area.

Frontal cortex

The part of the human brain associated with aggressiveness and impulse control. Abnormalities in the frontal cortex are associated with an increased risk of suicide.

Temporarily disrupting the dorsolateral prefrontal cortex function appears to alter how people use information about harm and culpability to render these decisions.
The lateral prefrontal cortex may diminish fear by decreasing activity in the amygdala similarly to the ventromedial prefrontal cortex, which inhibits the amygdala during extinction.
In 1989, Knight et al showed that unilateral prefrontal lesions increase the amplitude of middle-latency auditory evoked potentials, suggesting that the prefrontal cortex exerts an early inhibitory modulation of input to the primary auditory cortex in humans.
Two weeks after cessation of ATR exposure, rats were sacrificed by decapitation, brains were removed, and hypothalamus, prefrontal cortex, nucleus accumbens, and striatum were dissected on ice and frozen for HPLC analysis.
This restores dopamine levels in the prefrontal cortex preventing bruxism.
The study found that the most intense negative thinkers had higher levels of right prefrontal cortex activity and a pronounced startle reflex.
Monitoring single neurons within the right prefrontal cortex, the researchers found that these cells responded remarkably rapidly to unpleasant images, including pictures of mutilations and scenes of war.
The researchers examined tissue from the upper layers of the prefrontal cortex, an area of the brain used in complex reasoning, and counted two types of synapses.
Neuronal Mechanisms in Prefrontal Cortex Underlying Adaptive Choice Behavior
Sometimes, a part of the brain called the dorsomedial prefrontal cortex was more active during the rest period immediately before participants were asked to look at photos.
They include the hypothalamus; the striatal region, which includes the putamen and caudate and is in charge of motivation and reward; the limbic region, where emotion and memory reside; and the cortical region, which includes the prefrontal cortex, insula, and anterior cingulate cortex and handles the integration and processing of the brain.
Now, Mount Sinai scientists have begun to look elsewhere, focusing instead on synaptic health in the prefrontal cortex.
