Despite years of research, what regulates neurotransmitter release at synapses is still not fully understood. Physiological and ultrastructural approaches now reveal critical structural parameters of ...

Ca²⁺ influx into presynaptic nerve terminals activates synaptic vesicle exocytosis by triggering fast synchronous fusion and a slower asynchronous release pathway. In addition, a brief rise in Ca²⁺ ...

The release of calcium ions from the glia's internal stores is controlled by a series of different molecules. These can flow over gap junctions and trigger the release of calcium ions in adjoining ...

Neuroscientists at MIT's Picower Institute for Learning and Memory have found that a protein acts like a volume dial for the release of neurotransmitters, the chemicals that neurons release across ...
