Recording sessions in naïve mice. (A) Schematic representation of the recording setup. (B) Stimuli presented during the unimodal, audiovisual, and tuning blocks. (C) Organization of the unimodal, audiovisual, and tuning blocks in a recording session. (D) Two-photon image of V1 neurons recorded in a naïve mouse. The preferred orientation of the segmented neurons is indicated by the color scale in inset. White contours indicate segmented neurons that were not estimated orientation selective by the algorithm. (E) Example of the activity of neurons indicated in panel (D) during the presentation of the visual stimuli of the audiovisual block. The neuronal activity was recorded simultaneously with the locomotion of the animal as well as the pupil size (bottom traces).
