The aim of the project is to investigate the roles of optic flow, locomotion, visual landmarks, and contextual cues on retrosplenial cortex (RSC) neural activity. Calcium fluorescence signals of neuronal pupulation were collected in the superficial agranular RSC in mice running with head-fixed in a virtual reality (VR) and treadmill belt assay.

Calcium time courses of RSC neural activity in the reference frames of VR and treadmill belt. VR track length: 90 cm, treadmill track length: 150 cm.
Calcium time courses of RSC neural activity during closed-loop VR and open-loop VR
Calcium time courses of RSC neural activity in VR (random square pattern) with different gains between optic flow and locomotion: 1x, 2x, 0.5x, and 1x'
Calcium time courses of RSC neural activity in VR (blinking square pattern) with different gains between optic flow and locomotion: 1x, 2x, 0.5x, and 1x'
Calcium time courses of RSC neural activity in VR with 4 visual landmarks located at 9, 31.5, 54, 76.5 cm.
Calcium time courses of RSC neural activity in a triangle VR with 3 connected tunnels. Distinct contextual cues were presented at 3 vertices. Tunnel length: 100 cm.
