Neurobiology of executive functions: Catecholamine influences on prefrontal cortical functions

Recent evidence suggests that prefrontal cortical function is influenced by a valine / methionine variant in the catechol O - methyltransferase (COMT) gene.

Results: After controlling for multiple individual difference measures, dispositional mindfulness was associated with greater widespread prefrontal cortical activation, and reduced bilateral amygdala activity during affect labeling, compared with the gender labeling control task.

CONCLUSIONS: Early - onset antisocial behavior in a high - risk clinical group is predicted by a specific COMT gene variant previously linked with prefrontal cortical function and birth weight, and those possessing the val / val genotype are more susceptible to the adverse effects of prenatal risk as indexed by lower birth weight.

Genetic and prenatal environmental risk factors and prefrontal cortical function are thought to contribute.

Increase in prefrontal cortical volume following cognitive behavioural therapy in patients with chronic fatigue syndrome

Influence of Naturally Occurring Variations in Maternal Care on Prepulse Inhibition of Acoustic Startle and the Medial Prefrontal Cortical Dopamine Response to Stress in Adult Rats

The electrotonic structure of pyramidal neurons contributing to prefrontal cortical circuits in macaque monkeys is significantly altered in aging..

He made the seminal observation that repeated cycles of alcohol or Δ9 - THC intoxication and withdrawal result in progressive increases in impulsive action and impulsive choice, reflecting impaired prefrontal cortical function.

«The focus on a prefrontal cortical - linked task is particularly mission - relevant, since astronauts will need to have their executive functions in tip - top shape.»

Now associating ho.mose.xuality with «behavioral abnormalities» seems to be a stretch and I would think that any correlation between gay orientation and «maldevelopment of prefrontal cortical and ventral striatal dopamine systems» would be well docu.mented by now.

Future research will expand to include other cortical areas associated with motor skill learning, such as the prefrontal cortex and supplementary motor areas, according to Mr. Nemani.

Researchers focused on the medial prefrontal cortex and the precuneus, two cortical midline regions that are recruited when thinking about oneself.

«Our findings showed that an in increase in methylation of the SKA2 gene is associated with decreased cortical thickness in the prefrontal cortex, which may play a role in the development of PTSD and may explain why this gene predicts risk for mental health problems, like PTSD and suicide,» explained lead and corresponding author Naomi Samimi Sadeh, PhD, assistant professor of psychiatry at BUSM and a psychologist in the National Center for PTSD at VA Boston.

The excess was greater within DL - PFC than in M - PFC, a difference that parallels MRI volumetric data showing greater deviance in DL - PFC than M - PFC in living autistic toddlers.6 MRI studies show that enlargement is not restricted to DL - PFC and M - PFC; whether increased neuron counts in autism extend beyond these 2 major prefrontal subdivisions to include other cortical areas remains to be determined.

For her dissertation, Prerana developed several bacTRAP transgenic mouse lines to characterize molecularly distinct cortical pyramidal cell types, and focused on layer 2/3 pyramidal cell population in the prefrontal cortex that moderate stress induced depression related behavior.

In humans, decisions relating to the present involve regions of the brain (viz. limbic and paralimbic cortical structures) that are also consistently implicated in impulsive behavior and cravings such as heroin addiction, whereas decisions that pertain to the future involve brain regions (viz. lateral prefrontal and parietal areas) known to support deliberative processing and numerical computation.

More sustained early social isolation of young degus altered the serotonergic and dopaminergic cortical innervation in the orbital prefrontal cortex possibly reflecting different functioning of these monoamine transmitter systems in result of parental deprivation [133].

Because a nurturant early environment has been tied to better regulation of stress responses, a viable hypothesis is that a supportive family environment will be tied to greater cortical responses to threat and consequent lesser amygdala reactivity; activity in the amygdala and the right ventrolateral prefrontal cortex (RVLPFC) have been found to be negatively related in response to threat cues (17).

We hypothesized that whole - brain and region - of - interest analyses would identify differences in cortical thickness in prefrontal (especially anterior cingulate, middle frontal gyrus and orbitofrontal cortex) brain regions in female adolescents with early onset SUD, compared to controls.
