CIS increases dendritic arborization in BLA pyramidal neurons. A, Median values (horizontal line within each vertical bar) of total dendritic length for each successive 20 μm segment as a function of the radial distance of the corresponding segment from the soma (control cells, n = 18; CIS cells, n = 22). Inter-quartile ranges are represented by the lower (25th percentile) and upper (75th percentile) bounds of each vertical bar. B, Camera lucida drawings of representative Golgi-impregnated BLA pyramidal neurons from control and CIS-treated animals. Scale bar, 50 μm. C, Plots of median values and inter-quartile ranges for total dendritic length (top) and total number of branch points (bottom) for control (n = 18) and CIS (n = 22) neurons. *p < 0.05, **p < 0.01; randomized Mann–Whitney test.
