Researchers have found a way to study how our brains assess the behavior – and likely future actions – of others during competitive social interactions.
Harvard scientists have developed the fullest picture yet of how neurons in the brain interact to reinforce behaviors ranging from learning to drug use, a finding that might open the door to possible breakthroughs in the treatment of addiction.
A brain cell type found where habits are formed and movement is controlled has receptors that work like computer processors to translate regular activities into habits.
In efforts to find new treatments for Parkinson’s Disease (PD), researchers from the Perelman School of Medicine at the University of Pennsylvania have directly reprogrammed astrocytes, the most plentiful cell type in the central nervous system, into dopamine-producing neurons.
Stressed people fall into habits and their behavior is not goal-directed.
Researchers at The University of Texas at Austin have devised a simple test, using dopamine-deficient worms, for identifying drugs that may help people with Parkinson's disease.
A research team led by investigators at the Virginia Tech Carilion Research Institute has demonstrated the first rapid measurements of dopamine release in a human brain and provided preliminary evidence that the neurotransmitter can be tracked in its movement between brain cells while a subject expresses decision-making behavior.
Dopamine is more than just for pleasure! The lack of the brain chemical dopamine can rewire the interaction between two groups of brain cells and lead to symptoms of Parkinson’s disease.
Our data indicate that the brain becomes hypersensitive to rewards when this co-signaling of glutamate and dopamine does not function.
New research findings to be presented at the upcoming annual meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, finds that ghrelin, a natural gut hormone that stimulates feeding, also modulates the ability of tasty food and food-related cues to alter dopamine levels within the striatum, a critical component of the brainâ€™s reward system.
