Synaptic input–output properties in pyramidal, SP, and WM cells. A–C, Representative examples of input–output curves in pyramidal (A), SP (B), and WM (C) cells. Gray lines indicate the half-threshold PSP amplitude and stimulus intensity for each cell. Insets are PSPs for each indicated cell type on top. D, Plot of average ± SEM half-threshold PSP amplitude in pyramidal (black bar; n = 6), SP (light gray bar; n = 6) and WM (dark gray bar; n = 4) neurons. E, Plot of the average ± SEM. PSC amplitude at threshold evoked in voltage clamp at a synaptic stimulating current amplitude that was used for that same cell in current-clamp mode to evoke a PSP that was just below spike threshold for pyramidal (black bar; n = 6), SP (light gray bar; n = 6), and WM (dark gray bar; n = 10) cells. Insets are PSCs for each cell type below. Statistical comparisons are between WM and the other cell groups. **p < 0.01.
