Sentences with word «hypoactivation»

Studies of neural processing show that risk - taking may be associated with reward - related brain activation, with risk - taking behaviors and the opposite of what normally should happen (ie, hypoactivation with disappointment losses).

The boys with comorbid psychopathology also showed hypoactivation in response to rewards, consistent with reward insensitivity.

In comparing the patients in initial and follow - up study, the young patients had significantly reduced post-concussion symptom score at follow - up than at the time of the initial exam, but no significant change of the post-concussion symptom score was observed in the older patients, who also showed persistent hypoactivation.

Indeed, compared to a community control group of boys, adolescent boys diagnosed with comorbid conduct and substance use disorders exhibited hypoactivation in a number of brain regions comprising the limbic — striatal system (including the amygdala) and PFC regions during a risky decision making task with the possibility of gaining rewards [87].

The analysis revealed that while performing working memory tasks, the young patients with concussion had initial activation that was greater than normal, known as hyperactivation, compared to young controls in the right precuneus and right inferior parietal gyrus of the brain, whereas the older patients had hypoactivation (less than normal) compared to older controls in the right precuneus and right inferior frontal gyrus.
