Sensory determinants of behavioral dynamics in Drosophila thermotaxis.
Complex animal behaviors are built from dynamical relationships between sensory inputs, neuronal activity, and motor outputs in patterns with strategic value. Connecting these patterns illuminates how nervous systems compute behavior. Here, we study Drosophila larva navigation up temperature gradients toward preferred temperatures (positive thermotaxis). By tracking the movements of animals res...
متن کاملAn antennal carboxylesterase from Drosophila melanogaster, esterase 6, is a candidate odorant-degrading enzyme toward food odorants
Reception of odorant molecules within insect olfactory organs involves several sequential steps, including their transport through the sensillar lymph, interaction with the respective sensory receptors, and subsequent inactivation. Odorant-degrading enzymes (ODEs) putatively play a role in signal dynamics by rapid degradation of odorants in the vicinity of the receptors, but this hypothesis is ...
متن کاملMolecular basis for the behavioral effects of the odorant degrading enzyme Esterase 6 in Drosophila
Previous electrophysiological and behavioural studies implicate esterase 6 in the processing of the pheromone cis-vaccenyl acetate and various food odorants that affect aggregation and reproductive behaviours. Here we show esterase 6 has relatively high activity against many of the short-mid chain food esters, but negligible activity against cis-vaccenyl acetate. The crystal structure of estera...
متن کاملGroup Behavior: Social Context Modulates Behavioral Responses to Sensory Stimuli
A new study reveals an unanticipated role for social context in driving group behavior of a solitary species to a sensory stimulus and is mediated by mechanosensory neurons signaling touch interactions among individuals.
متن کاملAmino acid polymorphisms for esterase-6 in Drosophila melanogaster.
High-resolution electrophoresis has revealed 10 allozymes of esterase-6 (EC 3.1.1.1) in Drosophila melanogaster. The sequences of 13 isolates of the Est6 gene covering all 10 allozymes were obtained and 52 nucleotide differences were found. Sixteen of these cause amino acid replacements, of which three result in charge differences whose size and direction are consistent with the electrophoretic...
