Gjd2b −/− /Cx35.1−/− Light-ON VMR Hyperactivity is Reversed with Rod Photoreceptor Recruitment via Mesopic Light Exposure. (A) General overview of the mesopic VMR Assay. Zebrafish larvae were exposed to 5% light intensity to determine their sensitivity to mesopic vision. (B–C) Light-ON responses revealed that the recruitment of rod-PRC activity reversed the burst hyperactivity previously seen in gjd2b −/− /Cx35.1−/− Light-ON VMR responses. (D–E) Light-OFF responses were reduced in gjd2b −/− /Cx35.1−/− larvae. The statistical significance was determined by the Mann-Whitney test, p ≤ 0.05. The sample size (N) was 48 for WT and gjd2b −/− /Cx35.1−/− larvae.
