Laminar input to class II neurons.A, Percentage of class II neurons of each cell type receiving significant input from each layer. *A smaller percentage of type IIA neurons received significant layer 2/3 input than type IIB and IIC neurons (p = 0.045; Fisher's Exact test). **A smaller percentage type IIB neurons received significant layer 4Cα input than the other types (p = 0.02; IIA vs IIB, p = 0.04; IIC vs IIB,p = 0.04). B, Mean ± SEM of NEIs from each cortical layer for each cell type. ***Type IIC neurons received stronger layer 2/3 input than type IIA neurons (p = 0.046; Rank Sum test). ****Type IIB neurons received weaker layer 4C input than type IIA or IIC neurons (p = 0.01 for both comparisons). Gray bars represent type IIA neurons, black barsrepresent type IIB neurons, and open bars represent type IIC neurons. Conventions are the same as for Figure 3.
