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.
Synapse. There are chemical synapses, and  electrical synapses; chemical synapses involve  neurotransmitters diffusing across a small space between the  neurons, and electr â¦ ical synapses involve a much smaller gap called  a gap-junction, where ions move through channels resulting  in an electrical current.hen a signal reaches the end of a neuron it releases neurotransmitters into the synapse where they bind to receptors to release the second messenger into the next neuron.
