Stimulation of excitatory neurons causes a movement of ions
that results in a depolarization of the postsynaptic membrane.o These inhibitory postsynaptic potentials (IPSP) are generated
by the following:
1) Stimulation of inhibitory neurons releases neurotransmitter
molecules, such as ?-aminobutyric acid (GABA) or glycine,
which bind to receptors on the postsynaptic cell membrane.o These excitatory postsynaptic potentials (EPSP) are generated
by the following:
1) Stimulation of an excitatory neuron causes the release of
neurotransmitter molecules, such as glutamate or
acetylcholine, which bind to receptors on the postsynaptic cell
membrane.Neurodegenerative diseases
SYNAPTIC POTENTIALS
B. Inhibitory pathways
o Stimulation of inhibitory neurons causes movement of ions
that results in a hyperpolarization of the postsynaptic
membrane.
