... researchers thus confirmed the hypothesis formulated based on the computer model. The more the prefrontal cortex is activated, the greater the capacity of the parietal cortex for retaining short-term ...
... Investigators have programmed a complex virtual system that simulates a network of neurons, according to which the prefrontal cortex reinforces the activation of the parietal cortex. This hypothesis ...
... that brain regions involved with regulation of attention and reward, specifically the dorsolateral prefrontal cortex (DLPFC) and insular cortices, were significantly thinner in cocaine addicts when ...
... . “In birds, the exploratory phase ends when learning is complete,” he says. “But we humans can always call upon our equivalent of LMAN, the prefrontal cortex, to be innovative and learn new things.”
... ages, are more strongly associated with IQ and reduced volume of gray matter in the prefrontal cortex of the brain, which is involved in planning, complex thinking and moderating behavior.
Overall, ...
... serves to detect the presence of threatening information, and the prefrontal cortex, an area that functions to control these threat ... i.e., high amygdala, low prefrontal) did not.”

... and varying levels of “executive functioning” (the set of cognitive abilities overseen by the prefrontal cortex that control and regulate other abilities and behaviours), so confabulation cannot be as ...
... , the insula, which is associated with the prediction of monetary loss, and the mesial prefrontal cortex (MPFC), which is implicated in updating initial predictions of monetary gain.
Subjects showed ...
... report that Ritalin fine-tunes the functioning of neurons in the prefrontal cortex (PFC) - a brain region involved in attention, decision-making and impulse control - while having few ...
... to the participants.
The results clearly demonstrated that neural activity in the medial prefrontal cortex as well as in the right temporo-parietal junction linearly increased with the degree of " ...
... reveal only a part of the process, as results from previous studies have suggested that the prefrontal cortex might be one of many brain regions involved in intertemporal choice. "Future studies are ...
... in Biological Psychiatry, researchers found that the stimulant works by optimizing brain signals in the prefrontal cortex.
The researchers fed rats different doses of Ritalin and then studied their ...
... to control subjects. As Dr. Vawter further explains, "the pattern of dysregulation was similar in the prefrontal cortex for both illnesses and pointed to key processes. Part of the set of core ...
... .
The researchers made the discovery when studying the effects of estradiol on activities mediated by the prefrontal cortex, a brain region that is vital to working memory and to the ability to plan, ...
... (among other things) memory, emotional arousal and attention. The researchers said that more dopamine in the prefrontal cortex could result in an "inflexible attentional focus" on unpleasant stimuli, ...
