An excitatory synapse is a synapse in which an action potential in a presynaptic neuron increases the probability of an action potential occurring in a postsynaptic cell. Neurons form networks through which nerve impulses travel, each neuron often making numerous connections with other cells.
Glutamate is the major excitatory neurotransmitter in central nervous system (CNS) and as such the glutamate receptors play a vital role in the mediation of excitatory synaptic transmission (see animation). This process is the means by which cells in the brain (neurons) communicate with each other.lutamate is the major excitatory neurotransmitter in central nervous system (CNS) and as such the glutamate receptors play a vital role in the mediation of excitatory synaptic transmission (see animation).
