The aging process involves changes in neurotransmission at different levels. The purpose of this book is to help define the state-of-the-art of the field and to give directives for future research on the aging brain. Following topics are presented: the comparison of normal and pathological aging at the anatomical and neurochemical level; the knowledge of the responses of the aging brain to drug treatment or environmental stress; the neuro/immune and neuro/endocrine setting during aging; and the definition of therapeutical approaches in normal aging. This book will interest physicians and pathologists as well as neurophysiologists.Proceedings of the NATO Advanced Research Workshop on Modification of Cell to Cell Signals during Normal and Pathological Aging held at Salo, Garda Lake, Italy, September 22-27, 1986The aging process involves changes in neurotransmission at different levels.
