Abstract The responses to pure tone stimuli of individual auditory receptors in the locust Valanga irregularis were quantified and the location of receptors within the auditory organ identified through the intracellular injection of Lucifer Yellow. Three groups of receptors were identified and classified according to their site of attachment to the tympanic membrane (Gray 1960). Group 'a' cells were attached to the elevated process and were tuned to sound frequencies from 4 to 6 kHz (Fig. 2). Group 'c' cells were attached to the folded body and were tuned to sound frequencies from 2 to 3.5 kHz (Fig. 3). Group 'd' cells were attached to the pyriform vesicle and were tuned to sound frequencies from 14 to 25 kHz (Fig. 4). The receptor cell bodies belonging to these groups were separated into three distinct regions of the auditory organ (Fig. 5). There was no evidence of any tonotopic organisation within the three groups (Fig. 6). These data therefore support the conclusion that the receptors within the auditory organ of the locust are organized into specific physiological groups (Michelsen 1971a) and thus suggest that the mechanics of the auditory apparatus may indeed play a role in defining the tuning of the receptors.
