. The stereotyped response of the female Leptophyes punctatissima Bosc. to a representation of the male call has been taken as a behavioural measure to determine the directional sensitivity of monaurally deafened animals. By using the responses of an auditory interneuron (T‐fibre), the directional sensitivity could also be measured neurophysiologically on the same preparation. Thus it was possible to compare directly both a behavioural and a neurophysiological polar directional plot for an individual. Both methods provided very similar results, showing an overall directionality of about 15 dB, with the maximum sensitivity of the ear occurring on the ipsilateral side.
