The acoustic behaviour of the bushcricket Tettigonia cantans III. Coprocessing of auditory and vibratory information in the central nervous system

All the acoustic units in the ventral-nerve cord respond to both sound and vibration. Most of them show improved coding abilities when stimulated simultaneously with conspecific songs and vibration signals. This is also true for habituating neurons. Stridulating tettigoniids produce both airborne sound and substrate borne vibration and their simultaneous processing in the central nervous system may therefore lead to a better localization of a nearly sound source in the biotope.
