Neuroimaging study reveals structural and functional differences in brain areas associated with emotional regulation in those with personality traits linked to psychopathy or antisocial personality disorder.
Familial hemiplegic migraine type 2 (FHM2) causes a malfunction of astrocytes in the cingulate cortex. Manipulating astrocytes in the cingulate cortex reversed the disfunction, preventing an increase in migraine-like symptoms in mice carrying the FHM2 defect.
Study reveals how the brain's opioid system is linked to mood changes associated with depression and anxiety. Neuroimaging revealed, in those with depression, there is a decreased number of opioid receptors in specific areas of the brain.
Patients with psychosis who have higher levels of an antioxidant called glutathione responded more quickly to medications and had improved outcomes. Researchers estimate a 10% increase in antioxidants could lead to reduced time spent in hospital for those with psychosis.
Neuroimaging reveals areas of the brain associated with visual and auditory processing are more active when anxiety slowly increases during horror movies. After a shocking scene, brain areas associated with emotional processing, threat evaluation, and decision making increase in activity.
Yoga has a positive effect on the structure and function of key brain areas associated with memory. Findings provide evidence that yoga may hold promise in mitigating age-related and neurodegenerative decline.
