Descending control of motor sequences in Drosophila

Curr Opin Neurobiol. 2023 Dec 13;84:102822. doi: 10.1016/j.conb.2023.102822. Online ahead of print.ABSTRACTThe descending neurons connecting the fly's brain to its ventral nerve cord respond to sensory stimuli and evoke motor programs of varying complexity. Anatomical characterization of the descending neurons and their synaptic connections suggests how these circuits organize movements, while optogenetic manipulation of their activity reveals what behaviors they can induce. Monitoring their responses to sensory stimuli or during behavior performance indicates what information they may encode. Recent advances in all three approaches make the descending neurons an excellent place to better understand the sensorimotor integration and transformation required for nervous systems to govern the motor sequences that constitute animal behavior.PMID:38096757 | DOI:10.1016/j.conb.2023.102822
