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.
Glutamatergic system. Glutamate is the main excitatory neurotransmitter in the CNS. It is distributed so widely that it is impossible to talk about individual centres or projections. It plays an indispensable role in synaptic plasticity, i.e. the removal of old, unused synapses, potentiation of others and the formation of new synapses.
