Author’s contributions: BD, TM and T.-PS designed the project and designed the experiments. LC performed most of the in vivo experiments and analyses. CD, MD and MR performed visual motor response experiments. NC took care of the zebrafish. AD and SP performed in vitro experiments on aequorin and hippocampus. YY and SC performed biochemical and histological experiments. AD, SP and PP performed in vitro experiments and analyses. J.-CL performed zebrafish injections. T.-PS allowed access to S1R KO and NG-108 cells. BD and TM performed part of the in vivo experiments on mice, prepared the figures and wrote the manuscript. EMR implemented the manuscript.
