Combining deep-brain stimulation with intracranial EEG, researchers achieved an individualized understanding of specific brain networks that contributed to an individual's depression symptoms and identified stimulation patterns best suited to each patient for symptom relief.
The severity of PTSD symptoms was associated with fewer risky choices and increased activation of the amygdala. Decreased activity in the ventral striatum, an area of the brain associated with processing positive valence such as reward, predicted more severe PTSD symptoms 14 months post trauma.
The ventral striatum plays a key role in decision making, weighing the cost versus the benefit of making a physical effort.
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.
Researchers investigate the role the dopamine 2 receptor plays in psychosis.
Individual differences in the striatum of habitual cannabis users distinguish between who is at increased risk of addiction and cannabis use disorder.
Using fMRI to examine the brains of children while resting, researchers discover anhedonia is associated with hyperconnectivity between the cingulo-opercular network and ventral striatum.
Researchers report personality traits and psychological health impact how we value personal control when making decisions. The study reports brain activity in the motivation system is dampened in those with passive personalities and depression when we receive rewards that we have earned or feel in personal control of situations.
Ezogabine, an FDA approved anti-convulsant, appears to significantly reduce symptoms in those with major depressive disorder.
A neuroimaging study conducted by researchers from UCLA reveals the brains of people with schizophrenia are less sensitive to social rewards than they are to non-social rewards.
A new study examines the relationship between brain function and the impact of life events on depressive symptoms.
A new study reports people who have a family history of alcohol use disorder release more dopamine in the ventral striatum as a response to the expectation of receiving an alcoholic drink than those without a family history of alcoholism.
