Behavioural Studies on Auditory Development in Mammals in Relation to Higher Nervous System Functioning

Abstract

The development of hearing measured behaviourally is compared in a quantitative way with studies on the physiological development in the auditory pathway of cats, house mice and humans. The similarity of time constants and of the beginning and end of the developments suggests that behavioural threshold sensitivity measured by unconditioned and conditioned reflexes is determined at or below the midbrain level.
