Neurons are the cells that carry messages between parts of the body
... Neurons are separated by narrow gaps called synapses. When the action potential reaches the end of the axon it must pass to the next neuron. The neuron before the synapse (pre-synaptic neuron) releases chemicals called neurotransmitters in response to the action potential. ...

... The neuron is a mini decision maker. It receives info from thousands of other neurons-some excitatory (like pushing the gas pedal). Others are inhibitory (like pushing the breaks). If the excitatory signals, minus the inhibitory signals exceed a minimum intensity, called the absolute threshold, then ...
