Male crickets with both cervical and abdominal connectives cut failed to sing spontaneously. If only the cervical connectives were cut, spontaneously produced songs appeared within a few days after the operation (Fig. 1). Analysis of the time sequences of the chirps and pulses clearly reveal calling songs (Fig. 2) as well as transitions to courtship and rivalry songs. It is therefore clear that the cricket can produce songs even in the absence of neural commands from the head ganglia.
