Rich rewards: ADHD medication’s effect on the brain

Neuroscience NewsJanuary 17, 2020

Methylphenidate may boost norepinephrine levels in the prefrontal cortex, which in turn regulates dopaminergic neurons firing in the striatum, when a reward is delivered. The study sheds new light on how medications for ADHD affect the reward system in the brain.... Read More...

Promising steps towards hope for a treatment for schizophrenia

Neuroscience NewsOctober 4, 2019

Mu-opioid receptor (MOR) levels are significantly reduced in the striatum in those with schizophrenia. A lack of MOR system stimulation contributes to negative feelings, such as a lack of motivation and anhedonia, associated with the condition. Increasing MOR levels could help to reduce some of the symptoms of schizophrenia.... Read More...

How emotion affects action

Neuroscience NewsSeptember 13, 2019

Researchers have identified a comprehensive circuit mechanism that governs how emotional states can influence movement through connections in the basal ganglia. The mechanism represents a way in which emotional states relate to changes in action control in depression, anxiety, and OCD.... Read More...

Neurological brain markers might detect risk for psychotic disorders

Neuroscience NewsAugust 27, 2019

Researchers have identified a new biomarker for psychosis in the striatal dopamine neurons. Those at risk for psychosis showed increased activation in the striatum for positive feedback and decreased activation when faced with negative feedback.... Read More...

Brain activity may help predict success of CBT in depression

Neuroscience NewsAugust 1, 2019

Only 45% of patients with major depressive disorder find benefit from cognitive behavioral therapy (CBT). A neuroimaging study reveals those who respond to CBT have greater neural activity in the right striatum and right amygdala pretreatment than those who find little benefit from the treatment. The findings could serve as a biomarker to discover who will respond to CBT.... Read More...

Brain protein mutation from child with autism causes autism-like behavioral change in mice

Neuroscience NewsJuly 25, 2019

Researchers implanted a genetic mutation that encodes the DAT protein from a child with ASD into mice. The mice began to exhibit autism-like behavioral deficits. Mice with the DAT T356M mutation had reduced social interaction and a loss in social dominance. The mice also demonstrated an increase in hyperactivity. At the physiological level, the researchers found impaired striatal dopamine transmission and clearance.... Read More...

How the brain helps us make good decisions, and bad ones

Neuroscience NewsJune 25, 2019

The orbitofrontal cortex (OFC) appears to play a significant role in our ability to make decisions. A network connecting the OFC and nucleus accumbens translates negative outcomes into values, while the OFC-amygdala circuit helps stabilize action values.... Read More...
