Supplementary Figure 10: Features and principal component analysis for extracellular and juxtacellular recordings.
From: A novel pyramidal cell type promotes sharp-wave synchronization in the hippocampus
a) Summary statistics of features extracted from sorted extracellular units. b) Same as (a) but for features extracted from juxtacellular units. Note the higher burst index and number of spikes/burst afforded by the high signal-to-noise ratio of juxtacellular recordings. c) Principal component analysis of individual cellular features of extracellular sorted units (n = 203 cells). Eigenvectors related to each feature are superimposed (blue) with no clear segregation across the population. d) Principal component analysis of individual cellular features of juxtacellular units (n = 140 cells). Eigenvectors related to each feature are superimposed in blue. Note a segregation into two groups can now be observed (red dashed oval).
