An experimental small molecule helped restore the removal of mitochondria from dopamine-producing neurons in the brain. The findings may help in the development of new therapies for Parkinson's disease.
When a rat helps another within its social group, brain areas associated with reward and motivation become more active. This does not occur when a rat is faced with the prospect of helping another rat outside its social group. Researchers say the findings may provide a better understanding of similar social biases in humans.
People diagnosed with Alzheimer's or mild cognitive impairment had weaker gamma wave activation in their brains than their peers without the neurodegenerative disorders.
A rare genetic mutation interferes with dopamine transporters in the brain, causing Parkinson's-like symptoms in children.
A new mathematical model delves into the biological changes that occur in both the aging brain and brains with neurodegenerative disorders. The implications lay forth a new path into developing therapies for neurodegenerative disorders that affect cognition.
Olfactory imprinting in infant mice has a direct impact on their social behaviors as adults.
Adding selenium to diet products helps prevent obesity and increases healthy lifespan in mouse models.
Before symptomatic relapse of bipolar depression occurs, those with the disorder display a greater tendency towards pessimistic beliefs.
