Abstract

The 40 papers in this collection, first presented in 1963, have been grouped according to anatomical divisions of the nervous system, and as biochemical, neurophysiological, and behavioral aspects of its function. A discussion completes each of the five sections.

Cytological studies include early and late effects of irradiation with a-rays, x-rays, and60Co γ-rays; as demonstrated by light and electron microscopy; and some electrophysiological correlates. Techniques for making focal intracranial lesions with high-energy alpha particles are presented.

Physiological methods revealed alterations in resting potential of cell membranes after ionizing radiation as well as a differential sensitivity of tissues of various vertebrate, invertebrate, and plant species, when exposed in differing physiological states. Changes in sodium permeability of nerve membrane, in synaptic potentials, and in spinal reflexes are reported.

Alterations in histochemical reactions, aerobic, anaerobic, and lipid metabolism, enzyme activity and neural excitability, after x-irradiation, are presented, and radioisotope and autoradiographic
