How do nerve cells communicate?

Here is how neurons (nerve cells) communicate:

  1. An electrical signal travels down the axon.
  2. Chemical neurotransmitter molecules are released into the synapse.
  3. The neurotransmitter molecules bind to receptor sites on the releasing neuron and the second neuron.
  4. The signal is picked up by the second neuron and is either passed along or halted.
  5. The signal is also picked up by the first neuron, causing reuptake, the process by which the cell that released the neurotransmitter takes back some of the remaining molecules.
