Abstract
Changes in neurons, glial cells, synapse morphologic and electrophysiologic appearance, and neurotransmission mechanisms during normal aging are considered for review in this article. These processes not only are fundamental in the neurobiology of normal aging but also are implicated in the pathogenesis of aging.
