A model of the locust visual system under diverse stimuli highlights functionality of various mechanisms and suggests a parsimonious structure

The paper develops a model of the locust visual system to examine how different mechanisms interact with various stimuli, showing that inhibition plays key roles in shaping responses.

Background optic flow modulates responses of multiple descending interneurons to object motion in locusts

This study shows that background optic flow delays and shortens the response of motion-sensitive neurons in locusts to looming stimuli without affecting the number of responding units.

Complex motion trajectories are represented by a population code from the ensemble activity of multiple motion-sensitive descending interneurons in locusts

The paper investigates how locusts encode complex visual motion using neural recordings and dynamic factor analysis, finding that looming motion activates more neurons than translation.
