Description

Synapse, Neuron, Brain, the third and last volume in the series Medical Physics, focuses on neurons and their interactions. Comprised of seven chapters regarding the brain's synapses and nerves, this volume concludes through the presentation of medical physics and its applications. An introductory chapter of this volume provides the necessary basic concepts and theories needed in the understanding of the book. This is followed by a discussion on the brain and its interconnections with the spinal cord. Chapter 3 focuses on the importance of evoked potentials as a diagnostic tool for the sensory organ and the neural processing of the stimuli. Chemical and electrical properties of synapses are also given emphasis. Other topics covered in this volume include the rall theory and neuronal integration; membrane noise at synaptic junctions; and new techniques on brain studies (autoradiography, positron annihilation, and nuclear magnetic resonance). As with the other volumes, this also caters to persons in various disciplines such as medicine, physiology, physics, and biology.
