Abstract
The acoustic communication of crickets provides a model system for studying the mechanisms underlying sexual behavior. Female crickets walk toward a singing male. Two basic problems occur. Such phonotactic behavior is dependent upon recognition of the conspecific song and the localization of the sound source. Recognition is based upon the behavioral selectivity for the temporal pattern; neuronal correlates for this selectivity were found in the cricket brain. Localization is believed to be based on the excitatory difference between the two sides of the auditory pathway, even in animals with only one ear. By monitoring phonotaxis and simultaneously recording from identified auditory neurons one can clarify some causal relations between phonotaxis and neurons of the auditory pathway.
