Changes in Synaptic Structure Affecting Neural Transmission in the Senescent Brain
Neural transmission involves electrochemical interactions between two neurons along a region of interneuronal contact known as a synapse. In vertebrate nervous systems these interactions are mediated by transmitter substances, which react with receptor sites on synaptic membranes affecting their permeability to various ions. Synaptic membranes are modified segments of neuronal plasma membranes, and their properties vary in different types of synapses.
