CT_max precedes the brain-wide depolarization in freely swimming zebrafish larvae. (A) Schematic overview of the experimental setup for calcium imaging in freely swimming, 5-d-old Tg(elavl3:GCaMP6s) zebrafish larvae. (B) Top view of setup with color-coded time projection of a heat-ramp fish’s movements in the setup for 3 min (34 to 35 °C). (C) Representative images of brain fluorescence in the same fish as in B, before (Left) and during (Right) the brain-wide depolarization. (D) CT_max and depolarization-onset temperatures measured in heat-ramp fish (black circles; n = 7) (SI Appendix, Table S5). The bars and error bars indicate the mean and SE.
