Document Summary
Electrical synapse: conduct nerve impulses faster, but unlike chemical synapses, they lack gain (the signal in the postsynaptic neuron is the same or smaller than that of the originating neuron. Often found in neural systems that require the fastest possible response, such as defensive reflexes. Chemical synapse: synapse in which neurotransmitters are released, not as fast as electrical and are unidirectional. Synaptic potential: the difference in voltage between cells, can be excitatory and inhibitory. Responsible for sending signals between nerve cells, and under normal conditions it plays an important role in learning and memory. Gaba: made from glutamate, functions as an inhibitory nt. Glycine: amino acid, can be both excitatory and inhibitory, required to build protein in the body, for the synthesis of nucleic acids. Acetylcholine: functions in both the pns and cns as a neuromodulator. It is also found in sensory neurons in the cns, and has a part in rem sleep.
