Neuronal Information Transfer

Neuronal Information Transfer contains the proceedings of the symposium on Neuronal Information Transfer, held in Columbia University in June 1977. The symposium focuses on the molecular, ultrastructural, and morphological study of a number of systems showing defined receptor-effector interactions.
The collection of papers presented in the symposium provides insights into the understanding of nervous information transfer. The book includes findings and studies on the biogenic amine systems, cholinergic system, amino acid systems, and brain peptides and opiate system. Treatises that covered cyclic nucleotides and the neuronal structure and development are also presented.
Neuroscientists, neurologists, researchers, educators, and students in neuroscience will benefit from this book.
