This study investigates theÂ spatialÂ and directional tuning ofÂ Multi-UnitÂ ActivityÂ (MUA) inÂ mouseÂ primaryÂ visualÂ cortexÂ and how MUA can reflect spatiotemporal structures contained in moving gratings. Analysis of multi-shank laminar electrophysiological recordings fromÂ mouseÂ primaryÂ visualcortexÂ indicates a directional preference for moving gratings around 180Â°, while preferredÂ spatialÂ 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 decodingÂ spatialfrequency or direction of moving gratings, with average decoding performances of up to 58.54% for 8 directions, and 44% correctly identifiedÂ spatialfrequencies against chance level of 16.7%.
