Synaptic gradients transform object location to action

HIGHLIGHTS

  • who: Mark Dombrovski from the (UNIVERSITY) have published the article: Synaptic gradients transform object location to action, in the Journal: (JOURNAL) of 13/05/2022
  • what: The authors show through behaviour, physiology, anatomy and connectomics in Drosophila that visuomotor transformation occurs by conversion of topographic maps formed by the dendrites of feature-detecting visual projection neurons (VPNs)6,7 into synaptic weight gradients of VPN outputs onto central brain neurons. The authors demonstrate how this gradient motif transforms the anteroposterior location of a visual looming stimulus into the fly`s directional escape. For a second . . .
