  • Values are means ± SD; n is the number of cells; > significantly greater with P ≤ 0.005; ≫ significantly greater with P ≤ 0.001; –not significantly different. Statistically significant differences were determined using the Mann–Whitney U test. Electrophysiological parameters were measured as described in methods. Cluster 2 L6 and cluster 3 L6 correspond to layer VI neurons from clusters 2 and 3, respectively.
