New research from MIT suggests that astrocytes - long considered support cells - may play a key role in the human brain's ...

The human brain contains about 86 billion neurons. These cells fire electrical signals that help the brain store memories and ...

Presynaptic NMDA receptors are emerging as key modulators of synaptic transmission, and their activation is usually believed to be by the 'spillover' of presynaptically released glutamate.

neurotransmitters are stored in vesicles 1 and released by fusion of the vesicles with the presynaptic membrane. By analogy with the neuromuscular junction 2,3,4, the postsynaptic currents that ...
