Morphology and physiology of auditory interneurons of the bushcricket Gampsocleis gratiosa.
Seven types of auditory interneurons were characterized from the prothoracic ganglion of the bushcricket. They are sensitive in the range of 7-18 kHz and fire with distinct discharge patterns. They encode sound intensity and temporal parameters in various way. They show significant directional sensitivity, dependent on sound frequency. The acoustic tracheal system can partly account for the directional hearing of the bushcricket.
