Neural Pathways for the Detection and Discrimination of Conspecific Song in D. melanogaster

Abstract: These results reveal a critical pathway for courtship hearing in male and female flies, in which both aLN(al) and aPN1 mediate the detection of conspecific song. The pathways arising from these neurons likely serve as a critical neural substrate for behavioral reproductive isolation in D. melanogaster.

“…The choice between courtship and aggressive behavior is biased by situation-dependent acoustic signals that enhance motivation for one behavior while reducing motivation for the other. In light of recent work describing responsiveness of specific classes of projection neurons and local interneurons in the AMMC to courtship songs in both males and females, our results suggest that other neurons in the AMMC could be responsive to aggression songs in Drosophila males and thus that distinct neural circuits may exist that jointly control responsiveness to sound (30).…”

“…3H); however, this feature did not impact behavioral predictions (rank correlation between duration of the positive lobe and decoder performance ρ=−0.01, p=0.96). The range of filter durations may thus serve other aspects of song processing or other acousticallydriven behaviors (Lehnert et al, 2013;Vaughan et al, 2014). The relative homogeneity in response properties in our data set also makes it unlikely that females rely on any single neuron type when processing male song.…”

“…Given that our knowledge of higher-order auditory neurons in the Drosophila brain is limited (Lai et al, 2012;Zhou et al, 2014), the utility of our decoder model is that it posits simple algorithms for transforming the auditory codes of AMMC/VLP neurons into behavioral responses to courtship song. We propose that an AMMC/VLP neuron is read out by two downstream neurons.…”

“…For example, the Drosophila JO contains about 500 mechanosensory cells, $75% of which (subgroups A, B and D) have been linked to auditory function [71], but the ascending mechanosensory pathways for conspecific song detection are likely to have substantially fewer neurons [71][72][73]. In insect auditory systems, individuali.e., unique -neurons can be identified, and in some species a single neuron alone can drive important behaviors, such as the bat-evasion reflex in noctuid moths [74].…”
