During electrophysiology recordings, two PS3 Eye cameras were used to capture video of the mouse’s eye and whiskers. The whisker camera was positioned below the mouse’s head and recorded at 125 fps. The eye camera was positioned on the right side of the face and recorded at 60 fps. The OpenEphys Bonsai program was used to record video. Pupil size was measured from video offline using custom MATLAB code.

eLife Assessment This study presents a valuable finding on how the sensorimotor control system deals with redundancy within our body, based on a novel bimanual task. The evidence supporting the authors' claims is convincing, as demonstrated over four different experiments.

Our results indicate that, in naive mice, sound-evoked responses in S1 encode almost no information about the identity of auditory or audio-tactile stimuli. Nevertheless, there are reasons to believe a priori that experience and plasticity could alter this multisensory response profile.
