(5) Ions flow into the postsynaptic neuron, which generates an action potential when a threshold level is reached.

The transmission of information is accomplished in two ways: Electrically: the neuron is directly adjacent to other neurons. Small holes in each cell's membrane, called gap junctions, are juxtaposed ...
