Exploratory search during directed navigation in C. elegans and Drosophila larva
Many organisms-from bacteria to nematodes to insect larvae-navigate their environments by biasing random movements. In these organisms, navigation in isotropic environments can be characterized as an essentially diffusive and undirected process. In stimulus gradients, movement decisions are biased to drive directed navigation toward favorable environments. How does directed navigation in a grad...
متن کاملTwo Alternating Motor Programs Drive Navigation in Drosophila Larva
When placed on a temperature gradient, a Drosophila larva navigates away from excessive cold or heat by regulating the size, frequency, and direction of reorientation maneuvers between successive periods of forward movement. Forward movement is driven by peristalsis waves that travel from tail to head. During each reorientation maneuver, the larva pauses and sweeps its head from side to side un...
متن کاملReverse-correlation analysis of navigation dynamics in Drosophila larva using optogenetics
Neural circuits for behavior transform sensory inputs into motor outputs in patterns with strategic value. Determining how neurons along a sensorimotor circuit contribute to this transformation is central to understanding behavior. To do this, a quantitative framework to describe behavioral dynamics is needed. In this study, we built a high-throughput optogenetic system for Drosophila larva to ...
متن کاملEpsin potentiates Notch pathway activity in Drosophila and C. elegans.
Endocytosis and trafficking within the endocytosis pathway are known to modulate the activity of different signaling pathways. Epsins promote endocytosis and are postulated to target specific proteins for regulated endocytosis. Here, we present a functional link between the Notch pathway and epsins. We identify the Drosophila ortholog of epsin, liquid facets (lqf), as an inhibitor of cardioblas...
