When studying the relation between sensory physiology and behaviour, one is usually interested in the application of such studies to man; obviously, however, it is difficult to conduct studies directly on human subjects. This has led many workers to try to correlate single sensory nerve fiber activity in animals with discriminative ability in human subjects, or in the same species of animals, by conditioning experiments. Today, it is possible to study some electrophysiological bases of auditory behaviour directly in alert humans using non-traumatic techniques which permit the recording of gross electrical responses to sound stimuli of most parts of the auditory pathway — the auditory nerve (compound cochlear action potential), the brain stem auditory nuclei and the cerebral cortex. [This technique was originally designed to serve as an objective clinical test in cases of uncertain hearing diagnosis (Sohmer & Feinmesser, 1967) and is called electrocochleography (Sohmer et al., 1972)]. At the same time, behavioural responses to the same stimuli can be elicited from the same subject, so that electrophysiological-behavioural correlations are feasible.
