Study evaluates the effects of regular cannabis use on cortical dopamine function in youth at high risk of psychosis.
Neural patterns of activity in the medial prefrontal cortex associated with the intention to drink alcohol are influenced by the genetic risk for alcohol use disorder.
A new study in mice reveals a possible link between the use of SSRI antidepressants during pregnancy and an increased risk of autism-like symptoms in offspring. Offspring exposed to fluoxetine (Prozac) in utero were more likely to exhibit impaired neurotransmission caused by an overactive serotonin receptor in the prefrontal cortex, an area of the brain implicated in modulating social behaviors. However, treating the mice with a compound that blocks the receptor alleviated the behavioral problems and improved working memory.
Neuroimaging reveals those who have spent more years studying have increased cortical thickness in the medial prefrontal cortex, anterior cingulate and orbitofrontal areas of the brain. Researchers also identified enhanced gene expression profiles in these brain regions that promote information processing and provide protection against some age-related neurodegenerative diseases.
Researchers identified specific neurons in the medial prefrontal cortex, called self monitoring error neurons, that fire immediately after people make a mistake.
Researchers report older people may make riskier decisions than younger people.
Researchers report the medial prefrontal cortex calibrates current visual information with previously obtained information to help us perceive the world with more stability, helping to retain visual consistency as we blink.
A new study provides insight into the neurobiological underpinnings of envy. Researchers have identified a part of the brain that specifically registers when another receives a reward. This affects the subjective value placed on personal resources and rewards.
