Summary Introduction
To compare: Summation and facilitation.
Concept introduction:
Neurotransmitters are endogenous chemicals released by neurons and are localized in the presynaptic terminal (terminal end of the axon). These chemical signals are released into the synaptic cleft and bind to specific receptors on postsynaptic membrane of another neuron. Neurons in a specific portion of the brain can be directly or indirectly influenced by each neurotransmitter, thereby affecting behavior. The transfer of the impulses across the synapse depends on these neurotransmitters. In the synaptic cleft, these neurotransmitters bind to specific receptors in the membrane, on the post-synaptic side of the synapse.
