要旨:
Neurotransmitters are stored in, and
released from, synaptic vesicles. The
release of neurotransmitter, which
typically occurs in response to an
action potential in a Ca2+-dependent
manner, causes the postsynaptic
potential. When neurotransmitter is
released from only a single or a few
synaptic vesicles, the postsynaptic
potential is clearly seen to be
quantaI'. The uniform amplitude
of the quanta presumably reflects
the uniform volume and
neurotransmitter content of
synaptic vesicles
