Figure 3. STN contains distinct subpopulations.

A, Three activity vectors that were constructed based on theoretical predictions in Figure 1B and used as seeds for k-means clustering (see Methods). B, Each panel shows the average activity of neurons in a cluster, same format as Figure 2A. The numbers indicate the cluster size. C, Visualization of the clusters using the t-distributed stochastic neighbor embedding (t-SNE) dimension-reduction method. D, Average activity of clusters identified using random-seeded k-means clustering. Same format as Figure 3B. E, Visualization of the random-seeded clusters in the same tSNE space.
