Summary
[edit]DescriptionJPCA projections of the population responses.png |
English: Supplementary figure 4. The data contain multiple planes with rotations. Data are shown for two datasets (monkey
B and monkey J-array). Very similar findings were obtained for all datasets. Each column plots the first three jPCA planes (the top six jPCs) found within the top 10 PCs. All three planes contained rotational structure that was coherent (in the same direction and at a similar angular velocity) across conditions. However, rotations were slower (as expected) and less orderly for the higher-numbered jPCA planes. The top three jPCA planes (spanning six dimensions) captured 60% (monkey B) and 54% (monkey J-array) of the total variance in the data. |
