Fig 3. PV interneuron response half-width and amplitude do not vary with distance.

A. Half-width was uncorrelated with distance from stimulating electrode (R = 0.006, p = 0.854). B. Amplitude was uncorrelated with distance (R = 0.042, p = 0.170; Pearson’s product-moment correlation for both A and B). These results support the interpretation of single-cell responses, as half-width would be expected to increase, and amplitude would decrease with distance for population responses. Each point corresponds to one ROI identified by the procedure described in Methods. Linear regression best fit lines are shown in blue. N = 1086 cells from 52 slices.
