Correlation Matrices: Precision Pull vs. Treadmill Walking

Caption

Mathematical visualizations, or matrices, of the correlations of neural activity in the same mouse during each of the two tasks. Top left: Matrix sorted so that neurons with similar patterns of activity were clustered together. This boxy structure is indicative of similarly active neurons. Top right: When ordering the neurons the same way during walking, the clusters disappear. Neurons that are similarly active during one behavior are not similarly active during the other. Bottom left and right: The same holds true when clustering similarly active neurons, this time during walking.
