Summary: An artificial neural network has identified a potential mechanism for the impaired decision-making often seen in schizophrenia patients, which involves the reduced activity of NMDA receptors. Read More
Adult neurons in fruitfly brains produce extra copies of their genomes to help prevent cell death caused by DNA damage. Read More
Males with autism have atypically enhanced excitation in the medial prefrontal cortex (mPFC). This area of the brain is associated with social cognition and self-reflection. Autistic women showed a more intact mPFC response, which was associated with a better ability to camouflage social difficulties in real-world settings. Read More

People who have a high burden of ultra-rare protein-truncating variants (PTVs) have a shorter healthspan and lifespan. Each additional ultra-rare PTV in a person's genome accounted for a six-month reduction in lifespan and a two-month reduction in healthspan. Read More
Suicide survivors have higher pain tolerance and are less sensitive to bodily signals associated with their breathing and heart. Researchers found those who attempted suicide were able to tolerate the breath-hold and cold-pressor interoceptive challenges significantly longer than those who had no history of suicidal behavior. The interoceptive numbing was linked to lower brain activity in the insular cortex. Read More
Animal study reveals the formation of amyloid plaques drives brain tissue loss and neurodegeneration in Alzheimer's disease. However, lithium, a drug commonly used to treat bipolar disorder, reduces the life-shortening effects of the loss. Read More
During a conflict between two groups, oxytocin levels increase, influencing the medial prefrontal cortex. This results in a greater feeling of empathy among the group and a desire to seek revenge on rivals. The findings shed light on how conflict contagion can occur in social groups. Read More
Movement and sound are processed simultaneously in the inferior colliculus, a new mouse study reveals. Read More
Those who experience chronic adversity throughout life have impaired ability to produce sufficient dopamine levels to help them cope with stressful situations. Read More
Regardless of receptor types, spiking patterns determine vibrotactile frequency perception. The findings challenge existing theories about how Pacinian receptor channels work together in response to vibrotactile stimulation. Read More
A healthy and diverse microbiome is essential for quickly clearing viral infections in the nervous system to prevent risks associated with multiple sclerosis. Mice with lower gut bacteria had weaker immune responses and were unable to eliminate viruses, leading to worsening paralysis. Those treated with antibiotics before infection had fewer microglia.
