The spike protein of SARS-CoV-2 can pass through the blood-brain barrier of mice. The protein likely causes the brain to release cytokines and spark neuroinflammation. The findings add to growing evidence that COVID-19 can enter the brain of those infected by the virus.
Pnoc neurons in the paranigral ventral tegmental area become active when mice seek rewards. Stimulating these neurons with optogenetics promotes avoidance behaviors. Researchers say ventral tegmental area dopamine neuron NOPR expression is necessary to limit reward-seeking behavior.
Researchers have identified cognitive subgroups related to genetic differences in Alzheimer's patients. The findings, researchers say, could open the door for more personalized treatments of the neurodegenerative disease.
A new PNAS paper reports cannabidiol can help reduce epileptic seizures and improve social behaviors in children with Dravet syndrome.
