Extended Data Fig. 4: Categorization of cell types from unit features and tone response by cell type.

a. The tone response was significant in a larger proportion of interneurons than pyramidal cells (pyramidal cells: 46.7% responders; interneurons: 73.6% responders; p = 0.0142, chi-squared test). In the tone/oddball experiment (Figs. 2 and 3), we classified 45.3% of cells as pyramidal cells, 51.2% of cells as narrow interneurons, and 3.5% of cells as wide interneurons using conventional analysis tools (CellExplorer) based on their spike waveform and autocorrelogram features. In the language analysis (Fig. 4), we classified 65.3% of cells as pyramidal cells, 24.6% of cells as narrow interneurons, and 10% of cells as wide interneurons. b. Each subplot shows the plots the firing rate over time (mean ± SEM across cells) in response to tones. Vertical box: duration of the tone response. Shaded area is the mean ± SEM across all cells.
