Acetylcholine, a key neurotransmitter, plays a vital role in your body by facilitating communication between neurons in both the central and peripheral nervous systems. It is essential for muscle ...

Researchers have identified a mechanism by which acetylcholine, a neurotransmitter best known for its role in muscle control and attention, can effectively commandeer serotonin release inside the ...

Scientists have long-studied the role of dopamine, a chemical in the brain that helps control learning and movement, in order to better understand Parkinson's disease, schizophrenia, and ...

Neurons perform numerous complex tasks by communicating with each other via small messenger molecules called neurotransmitters. Accurately detecting them is crucial to understanding the functioning of ...

Acetylcholine regulates blood flow, but the source of blood acetylcholine has been unclear. Now, researchers at Karolinska Institutet have discovered that certain T cells in human blood can produce ...

Increases (hyperglycemia) and decreases (hypoglycemia) in blood glucose concentration can be fatal and are efficiently prevented by the secretion of pancreatic islet hormones. The concerted output of ...

Memory dysfunction in Alzheimer's disease may be linked to impairment in how the brain replays our recent experiences while we are resting, according to a new study in mice by University College ...

Two new reports this week show what can happen when neurotransmitters get out of whack, with ramifications for Alzheimer disease and Parkinson disease. First, a paper in the September 7 Neuron ...
