Neurotransmission Notes
... The sending neuron reabsorbs any excess NT’s left in the synapse. This is called reuptake. Neurotransmitters can be excitatory (causing EPSP’s or excitatory post-synaptic potential) or inhibitory (causing IPSPs or inhibitory post-synaptic potential). Excitatory NTs bring the dendrite closer to thres ...
