AN INVESTIGATION OF OLFACTORY CENTRIFUGAL FIBER SYSTEM

Abstract
An exploration was made of the functional significance of known centrifugal paths to the olfactory bulb by observing effects of their excitation, in the curarized cat, upon the resting electrical activity or that induced in the bulbs by olfactory simulation. It appears that the centrifugal fibers exert a depressive influence upon induced afferent activity in the bulbs and there is indication that this influence may act in a tonic fashion.
