Behavioral responses in an object segmentation task and neural responses during passive viewing

The rodent visual system has attracted great interest in recent years due to its experimental tractability, but the fundamental mechanisms used by the mouse to represent the visual world remain unclear. In the primate, researchers have argued from both behavioral and neural evidence that a key step in visual representation is “figure-ground segmentation,” the delineation of figures as distinct from backgrounds [1–4]. To determine if mice also show behavioral and neural signatures of figure-ground segmentation, we trained mice on a figure-ground segmentation task where figures were defined by gratings and naturalistic textures moving counterphase to the background. Unlike primates, mice were severely limited in their ability to segment figure from ground using the opponent motion cue, with segmentation behavior strongly dependent on the specific carrier pattern. Remarkably, when mice were forced to localize naturalistic patterns defined by opponent motion, they adopted a strategy of brut..., Datasets were collected per methods in https://www.biorxiv.org/content/10.1101/2021.07.04.451059v1. , Instructions for loading data are included in README.MD
