Data for the paper, "Locomotion selectively enhances visual speed encoding in mouse medial higher visual areas". These data include electrophysiology recordings from different mouse visual areas collected using multiple NeuroPixel high-density electrodes. Data were collected in awake head-restrained mice viewing visual stimuli and able to run over a treadmill. Data uploaded here is processed data from the Allen Institute dataset, and the orginal dataset was published here: Siegle, J. H. et al.
