Neurobiology: Backchat at the synapse
Patricia C. Salinas1
Abstract
At synapses, nerve cells release neurotransmitters, which affect other nerve cells or muscles. Studies of how muscles in turn influence neurotransmitter release hint at how synapses adapt to changes in use.
Synapses — points of contact between a nerve cell and its target — are dynamic structures that can grow, shrink and change their properties according to their firing history. Crosstalk between the 'presynaptic' neuron (which releases neurotransmitter molecules when stimulated) and its 'postsynaptic' target (which responds to the neurotransmitters) is crucial for the formation, maturation and refinement of synapses.
