Audtiory Input to the Dorsal Longitudinal Flight Motor Neurons of a Noctuid Moth

Part of the NATO ASI Science book series (NSSA, volume 156)


The motor neurons (mn) innervating the dorsal longitudinal muscles (dlm) receive synaptic inputs activated by auditory pathways. Quiescent mn’s in a “non-flying” preparation receive either subthreshold depolarizing or hyperpolarizing synaptic inputs in response to ultrasound. On the other hand, sound stimuli presented to a “flying” preparation can modulate motor neuronal responses in different ways depending of some unknown state of the nervous system. Sound intensity is the stimulus parameter that triggers responses. The modulation of neuronal responses has significance for the insect’s avoidance behavior to bats.
