Abstract
This study investigates the spatial and directional
tuning of Multi-Unit Activity (MUA) in mouse primary visual
cortex and how MUA can reflect spatiotemporal structures
contained in moving gratings. Analysis of multi-shank laminar
electrophysiological recordings from mouse primary visual
cortex indicates a directional preference for moving gratings
around 180 , while preferred spatial frequency peaks around
0.02 cycles per degree, which is similar as reported in single-unit
studies. Using only features from MUA, we further achieved a
significant performance in decoding spatial frequency or direction
of moving gratings, with average decoding performances
of up to 58.54% for 8 directions, and 44% correctly identified
spatial frequencies against chance level of 16.7%.
