Different molecular mechanisms cooperate to the regulation hormones, local metabolic of brain microcirculation: products, transmitterso Great interest has recently emerged in literature on the neuronal systems controlling the blood brain barrier and on the reciprocal interaction between neuronal activity and vascular supply. In particular, this volume on the NATO Advanced Research Workshop held in Salo' (BS), Italy, September 3-8, 1988, outlines the importance of neuron-vessel communication in the regulation of cerebral microenvironment. The problem is approached from a multidisciplinary...
