Researchers find key to keep working memory working

Neuroscience NewsMarch 19, 2020

Acetylcholine helps muscarinic M1 receptors in the prefrontal cortex to maintain information in working memory. As acetylcholine actions at M1 receptors are reduced in conditions which affect working memory, such as schizophrenia and Alzheimer's disease, researchers report the M1 receptor may serve as a potential therapeutic target to restore working memory....

Junk food orders up trouble for young brains

Neuroscience NewsMarch 10, 2020

Everyone knows consuming junk food is bad for your health, but a new study reveals it could also be bad for developing brain health. Excessive consumption of calorie-dense foods can lead to changes in the structure and function of the prefrontal cortex, including altering dopamine signaling and inhibition.... Read More...

Children’s mental health affected by sleep duration

Neuroscience NewsFebruary 4, 2020

Shorter sleep duration can increase the risk of children developing depression, anxiety, and cognitive problems. Children who routinely suffered sleep disruptions or shorter sleep durations had reduced brain volume in the orbitofrontal cortex, prefrontal cortex, precuneus, supramarginal gyrus, and temporal cortex....

Hot flashes impair memory performance

Neuroscience NewsJanuary 23, 2020

Vasomotor symptoms, including hot flashes in postmenopausal women, may contribute to memory performance problems. Neuroimaging reveals hot flashes caused alterations in brain function during memory encoding and retrieval tasks, specifically within the hippocampus and prefrontal cortex.... Read More...

Violence and adversity in early life can alter the brain

Neuroscience NewsJanuary 17, 2020

Exposure to violence and childhood adversity has a negative effect on the developing brain. Neuroimaging reveals adolescents who experienced adversity and violence as children had reduced connectivity between the amygdala and the prefrontal cortex. However, social support may act as a buffer and reduce the negative effects of early life stress.... Read More...

Study sheds light on link between cannabis, anxiety and stress

Neuroscience NewsJanuary 13, 2020

A naturally occurring molecule produced by the brain activates endocannabinoid receptors, protecting against stress by reducing anxiety-producing connections between the amygdala and the prefrontal cortex. The findings may help explain why people turn to marijuana when they feel anxious or stressed.... Read More...
