A new collection of fly strains comprehensively targets the motor neurons of the proboscis, allowing separate control of every muscle to determine how this appendage achieves flexible, directed reaching.
Discovery of a novel neuropeptide signalling system in a deuterostome invertebrate reveals the evolutionary origin of prolactin-releasing peptide and its relationship with neuropeptides in protostome invertebrates.
Identification and functional characterization of the first non-chordate kisspeptin neuropeptide system in the sea cucumber indicates the ancient origin of the intracellular signaling and physiological functions of this molecular system.
Vps29 promotes retromer localization in the adult Drosophila brain, engaging Rab7 and TBC1D5, and its loss triggers age-dependent neuronal impairments in endolysosomal trafficking and synaptic transmission.
Demonstrating extreme diversity across crustaceans while contrasting with evolutionary stability in insects, mushroom body homologues further underpin the unity of Pancrustacea and shed new light on arthropod brain evolution.
