Definition
English
:
The
communication
from a NEURON to a target (neuron, muscle, or secretory cell) across a
SYNAPSE
. In chemical
synaptic transmission
, the presynaptic neuron releases a NEUROTRANSMITTER that diffuses across the synaptic cleft and binds to specific synaptic receptors, activating them. The activated receptors modulate specific
ion channels
and/or second-messenger systems in the postsynaptic cell. In electrical
synaptic transmission
, electrical signals are communicated as an ionic current flow across
ELECTRICAL SYNAPSES.
