Synapse
Definition:
Example Sentences:
(1) Synapse loss was accentuated, however, within immature and mature plaques.
(2) The capacity of granule-cell networks to separate overlapping patterns of activity on their inputs is adequate, with spatial variability in the secretion at synapses, but is improved if there is also temporal variability in the stochastic secretion at individual synapses, although this is at the expense of reliability in the network.
