Extended Data Fig. 6: PCA with k-means clustering.
From: Large-scale neural recordings with single neuron resolution using Neuropixels probes in human cortex
PCA with k-means clustering. a. Percent variance explained by each principal component calculated across the first 6 channels per unit. b. Silhouette values for each k-means cluster number for the first 40 principal components after re-running the k-means clustering analyses 20 times (including 1000 iterations). Error bars indicate SEM over the repeated clustering analyses. c. Scatter plot of seven clusters (using k-means clustering) in the first three principal components. Color coding reflects different clusters.
