The co-chairmen of the conference, H. W. Magoun and F. Fremont-Smith, assembled a distinguished group of 29 participants from the United States, Canada, England, Germany, Argentina, Brazil, and Russia, who discussed certain specialized areas of brain function. Beginning with an admirable historical review by Brazier, the volume includes papers on ultrastructure and chemical organization of synapses; spreading depression; steady potential shifts; metabolic and electrical measurements, with isolated cerebral tissues; and the effects of transcortical polarizing currents on learning and on steady potential shifts in learning. The first portion of the volume ends with consideration of unidirectional potential shifts in petit mal.

The second portion consists of three papers concerned with space biology. The first deals with certain aspects of brain physiology in the space environment; the second, with studies of brains exposed to cosmic rays and to accelerated alpha particles; and the third, with some relations of basic research to
