chemical signals diffuse between neurons at this location
Figure 2.2: Neurons transmit information to other neurons. Information passes from the axon of the presynaptic neuron to the dendrites of the postsynaptic neuron. Figure 2.3: The synapse is the site where chemical signals pass between neurons.hen the neuron is stimulated, the electrical signal (action potential) travels down the axon to the axon terminals. When the electrical signal reaches the end of the axon, it triggers a series of chemical changes in the axon terminal.
