In grasshoppers, the auditory and vibra- tional senses converge on the same ventral-cord neurons. All neurons in the ventral cord that discharge impulses in response to either airborne-sound or vi- bration stimuli also receive synaptic inputs from the other sensory system. The latter elicit either sub- threshold excitation or inhibition.
The coding of the conspecific song in the responses of most ventral-cord neurons of Tettigonia cantans is considerably improved when the stimulus consists not of simulated natural sounds alone, but of such
Stridulating tettigoniids produce both airborne and substrate-conducted sound. Thus the perception of airborne sound and vibration, and their simulta- neous processing in individual ventral-cord neurons, may be of fundamental importance - not only in localizing a nearby sound source, but also in facilitat- ing the recognition of conspecific signals.
The coding of airborne-sound and vibration signals in bimodal ventral-cord neurons of the grasshopper Tettigonia cantans
