A fluorescent probe designed to incorporate a fluorophore into the structure of a neurotransmitter finds activity-dependent heterogeneity in dopamine release at individual synapses ...

Many medical and psychiatric conditions involve neurotransmitter dysfunction. Alzheimer’s disease, a type of dementia, is associated with a decline in acetylcholine activity in the hippocampus ...
