Randomized trial identifies distinct sleep states in Drosophila, suggesting genetic regulation mechanisms.

This research aims to uncover the genetic mechanisms underlying various sleep states in Drosophila melanogaster.
Analyzed locomotor activity data from 10,130 Drosophila flies across 168 genotypes using hidden Markov models (HMMs).
Determined optimal sleep/wake state models based on statistical and information theory criteria.
Performed genome wide association analysis with 2,189,692 polymorphisms to identify candidate genes related to sleep states.
Achieved over 99% accuracy in classifying sleep/wake states using a 4-state HMM with 1000 iterations.
Identified 989 SNPs in 505 candidate genes associated with various sleep states, with 376 having human orthologs.
Noted significant heritability (0.27-0.50) impacting the duration of sleep states observed in flies.

Ghosh et al. (2026) studied this question.
