Messages travel along a single neuron as "electrical impulses" (also known as “nerve impulse” which is an electrical signal that travels along an axon), but messages between neurons travel differently. Messages, in the form of electrical impulses, constantly travel back and forth between the brain and other parts of the body.
The transfer of information from neuron to neuron takes place through the release of chemical substances (chemical message) into the space between the axon and the dendrites. These chemicals are called neurotransmitters, and the process is called neurotransmission. The space between the axon and the dendrites is called the synapse.
The most important thing you’re going to need in order to pass a final exam is your brain. And when studying for finals, you are strengthening brain connections, as well as allowing for even more distant connections or “associations” to be made.
