The contact between neurons is an electrical and chemical process through which one delivers the information for the next neuron. An electrical stimuli that gets delivered from the dendrites (the collection branches of a neuron to take in information from the alternative neurones), that goes through the cell body, then it goes way down to the long arm of the neuron, that’s called an axon. This accelerated electrical signal moves down a neuron is called an action potential. When this electric gets on going (action potential) it goes to the end of the neuron (presynaptic terminal), a complicated chemical response is triggered. At the end of a neuron there is small bodies that are called synaptic vesicles. The vesicles have assorted chemicals that’s called neurotransmitters.
A neurotransmitter is a chemical that is a messenger. The action potential which has travelled down the axon causes the release of the neurotransmitters, and then flood out of the neutron in a small space called a synapse or either synaptic cleft. Neutrons don’t physically touch, alternatively they’re separated by minute gaps called synapses. The chemicals (neurotransmitters) get released from the neutron into this gap, where they go across the gap to the next neuron.
