It generally depresses activity of neurons. It stimulates only certain key neurons or pathways. A. True B. False 33. Synaptic vesicles containing NT are produced in the postsynaptic cell. The passage of an AP along an axon represents a temporary change in potential across the membrane of that axon.
Chemical synapses carry information, but do so in only one direction.
An AP propagating along an axon comes to the axon terminal where it encounters a chemical synapse. The AP jumps over the very small synaptic gap and continues propagating along the postsynaptic cell. Both the size and charge of an ion affects its ability to move through channels in the membrane of a neuron.
