Detailed explanation-1: -These chemicals are called neurotransmitters, and the process is called neurotransmission. The space between the axon and the dendrites is called the synapse. When neurons communicate, an electrical impulse triggers the release of neurotransmitters from the axon into the synapse.

Detailed explanation-2: -For communication between neurons to take place, an electrical impulse triggers the release of chemicals called neurotransmitters. Neurotransmitters are released into the space between the two neurons.

Detailed explanation-3: -Axon – The long, thin structure in which action potentials are generated; the transmitting part of the neuron. After initiation, action potentials travel down axons to cause release of neurotransmitter.

Detailed explanation-4: -Glutamate is the major excitatory neurotransmitter in the mammalian brain. Fast transmission mediated by this neurotransmitter accounts for synaptic excitation of most, if not all, brain neurons (Kandel et al. 2000), and thus glutamate is found throughout the brain.

Detailed explanation-5: -Four neurotransmitters come under the chemical classification of biogenic amines. These are epinephrine, norepinephrine, dopamine, and serotonin.
