1. Removing the anterior tympanic membrane of the tettigoniidCaedicia simplex did not significantly alter either the tuning or the intensity-response characteristics of individual auditory fibers recorded in the leg nerve (Figs. 2 and 3). However, th

1. An ascending, auditory unit has been extracellularly recorded from the cervical connective in specimens of two tettigoniid species. Spike potentials arising from unilateral afferent input were monitored in response to airborne sounds in the freque

1. The accuracy with whichTeleogryllus oceanicus females orientate to synthetic calling songs, containing carrier frequencies in the range 2.5 kHz to 12 kHz, has been quantified in terms of the angle of incidence of stimulation (target angle) during

1. Physiological responses of individual primary auditory fibres in the tettigoniidCaedida simplex were quantified for sound frequencies between 5 kHz and 35 kHz and the anatomical organisation of the central projections of several fibres was determi

1. Electrophysiological recordings from individual auditory sensilla in the tettigoniid (Caedicia simplex) ear (Fig. 1) show that spike potentials of two distinct amplitudes occur in the sensory neuron (Fig. 2). Generally, the smaller of the two clas

Physiological recordings were obtained from identified receptors in the tympanal organ of Gryllus bimaculatus. By immersing the prothoracic leg in Ringer solution and removing the anterior tympanic membrane the auditory receptors were exposed without

1. The gross anatomical features of the crista acustica in the tettigoniids Mygalopsis marki and Polichne sp. are compared (Fig. 1). The crista in Polichne sp. was longer and contained 12 more receptors than that in M. marki. Both organs, however, di

1. Single unit recording from the oesophageal connectives was used to characterise the physiological responses to monaural stimulation of ascending auditory interneurons in the tettigoniidCaedicia simplex. 2. In terms of characteristic patterns of sp
