Note: The “Animal identifier” column lists our identifying code for a particular animal. “Number of stimuli” indicates the number of different orientations that were used for collecting OI response maps. In several cases (animals 2303, 1206, 1606, 1906, and 2006), more than one recording session was used for analysis. The total number of single-condition maps collected for an animal is indicated in brackets. The exact age in weeks was not available for animals 2806 and 0408. “Imaging technique” lists the type of imaging used to record the cortical response. Area 17 (primary visual cortex) was imaged in all animals.
