Abstract

In May, 1950, Prof. Frédéric Bremer gave three lectures at the University of London, which are now published. In the first, "Synaptic Transmission, Inhibition, and Auto-Rhythmicity in the Spinal Cord," reference is made to the concept that incoming impulses set up depolarization of the nerve cell, spreading electronically along the axon. Excitation and inhibition are discussed in terms of polarization changes and the role of chemical mediators. Autorhythmicity in the spinal cord is believed to find support in properties of reflex after-discharge, postural contraction, and oscillography.

The lecture on "Physiological Basis of Electroencephalography" deals with isolated whole brain and cerebrum preparations. Concepts of reverberating circuits and electrotonic changes are explored in explaining arousal effects, inherent rhythmicity, and the nature of the functional sign of spontaneous electrical activity.

In "The Auditory Area of the Brain: An Oscillographic Study of Its Activity," Bremer summarizes the evidence for localization of the primary and
