Distinct associative learning abilities for colour and odour in the flower-feeding Drosophila elegans and the fruit-feeding Drosophila melanogaster

This study compares odour and colour associative learning in two Drosophila species, finding D. elegans has better colour learning but worse odour learning than D. melanogaster.

Mating status-dependent dopaminergic modulation of auditory sensory neurons in Drosophila

This study shows that dopaminergic signaling via Dop1R2 modulates auditory sensory neuron responses in Drosophila females based on their mating status, affecting song response behavior.

Neural-circuit basis of song preference learning in fruit flies

This study identifies reciprocal neural circuits between pC1 and pCd-2 neurons in Drosophila that mediate song preference learning through GABAergic and dopaminergic inputs.

Auditory experience prevents loss of the innate song preference as a selective cue in Drosophila

This study shows fruit flies have an innate preference for conspecific courtship songs, which requires auditory input and can be reacquired during aging.

A hybrid versatile method for state estimation and feature extraction from the trajectory of animal behavior

This paper introduces a hybrid machine learning method to estimate behavioral states and extract features from low-content animal trajectory data, validated across diverse species and environments.
