Nerve06/autonomic nervous system and synapses/excitatory and inhibitory synapsesのソースを表示

When synaptic transmitters, such as adrenaline, nor-adrenaline, acethylcholine, are released, the post-synaptic membrane depolarizes and the threshold is lowered (left half of figure).  Such synaptic transmission is excitatory.  When synaptic transmitters, such as GABA is released, the post-synaptic membrane hyperpolarizes, and the threshold is hightened (right half of figure).  Such synaptic transmission is inhibitory.
