Fig. 3: Orientation representation and behavioral performance in unimodal and audiovisual contexts.

a Go and NoGo stimuli used during the training and recording sessions (top left panel) for a second experimental group for which we alternated unimodal and audiovisual blocks. During audiovisual blocks, Go and NoGo cues were presented simultaneously with either a 5 kHz or a 10 kHz tone. Recording sessions ended with a tuning block (bottom panel). b Behavioral performance of the mice during the unimodal visual (light grey) and audiovisual (dark grey) blocks of the different recording sessions. Black lines indicate mean ± s.e.m. across sessions. Permutation test: *p < 0.05; ***p < 0.001. Circles indicate individual mice (thick lines indicate significant differences between unimodal and audiovisual performances; p < 0.05). Grey circles indicate sessions for which only the behavior data was used. c Same representation as in (b) for the FA rate. d Left panel: mean activity evoked in the orientation space by the Go (45°, blue) and NoGo (70°, red) cues during the two first seconds of the unimodal visual stimulus presentation. Right panel: mean activity evoked in the orientation space by the same Go (45°, green) and NoGo (70°, yellow) stimuli during the same period in the audiovisual context. Vertical colored lines indicate the orientation of the presented stimulus. Shaded areas indicate the s.e.m. e Violin plot of the distribution of the location in the orientation space of the peak of activity for unimodal NoGo (red) and audiovisual NoGo (yellow) pseudo-trials. Black stars indicate the orientations of the presented NoGo stimuli.
