Neomycin-treated whole-brain responses to water flow. A, Normalized distribution of the r² values from the linear regression of each fluorescence trace for every ROI to the water flow stimuli, WT in orange and neomycin-treated, with their lateral line ablated, fish in blue (n = 3). B, Clustered responses, after filtering on the r² values as we did in Figure 2 from the neomycin-treated fish, average responses (left), and heatmaps (right). Colored rectangles at the bottom indicate the timing of the stimuli (magenta for h-t, green for t-h).
