Fig. 4 Neurons in the posterior tuberculum respond to changes in illumination.

a Raster plot of mean calcium responses (mean of three trials) from GCaMP6s expressing PT neurons. Color scale denotes standardized change in fluorescence intensity (ΔF/F). Illumination conditions as indicated on the X axis (light ON, orange; dark, gray). Only a subset of no-response neurons are included. b Location of light OFF-responsive neurons in the rostral PT. Scale bar indicates fluorescence (ΔF/F) change over baseline. c Mean and standard error for response of light OFF- (green, N = 46) and light ON- (purple, N = 14) responsive neurons. d Mean and standard error for response of light OFF- (green, N = 8) responsive neurons during the 3-min dark period. e Peak change in fluorescence for neurons that respond to light OFF in the left (PTL) and right (PTR) PT for larvae classified as left (red) and right (blue) motor-biased. f Location of light OFF-responsive neurons within the PT for larvae behaviorally identified as left- (red) or right- (blue) biased. Error bars represent standard error of the mean. Box plots show median and quartiles with whiskers indicating 10–90%. Source data are provided as a Source Data file.
