Most of the focus has been on improving functioning of the prefrontal cortex
," he says, "but our study suggests that if you could improve GABA activity within the hippocampus, this may help people to stop unwanted and intrusive thoughts.
Most previous studies coherently agreed that presynaptic DA in striatum and prefrontal cortex
increased, triggering psychotic positive symptoms.
The section of the medial prefrontal cortex
of the control group showed deeply stained Nissl substance throughout the cortical layers (Figure 4a).
These data support Antonio Damasio's (1994) Somatic Markers Hypothesis that damage or dysfunction in the prefrontal cortex
(specifically the ventromedial frontal lobe) reduces the person's emotional responsivity.
In contrast, soldiers with PTSD responded with reduced activity in the dorsal lateral prefrontal cortex
and a decline in memory task performance--regardless of whether the distracting images depicted combat or noncombat scenes.
Two patients with a history of tinnitus and medication-refractory depression had been participating in a study to evaluate the antidepressant efficacy of rTMS delivered to the dorsolateral prefrontal cortex
Key words: atrazine, dopamine, hypothalamus, locomotor activity, microdialysis, prefrontal cortex
, striatum, substantia nigra, unbiased stereology.
In obesity, we didn't see any problems in the prefrontal cortex
," says Dr.
The study pinpointed the centre of the placebo response in the prefrontal cortex
area of the brain.
In experiments with rats, the researchers examined the effects of stress on the function of a brain area called the prefrontal cortex
, or PFC, which governs cognitive abilities such as short-term memory and concentration.
A brain scan study showed that two neural zones - the anterior cingulate cortex (ACC) and the right ventral prefrontal cortex
(RVPC) - which respond to physical pain also react to social exclusion.
Researchers measured the electrical activity in the right and left sides of the brain's prefrontal cortex
which are associated with positive and negative mental states.
