Figure 4

A loss of whisker inputs leads to plastic changes in the apical and basal dendrites of pyramidal neurons in the barrel cortices. A) Top panels show the images of apical dendrites (left) and basal dendrites (right) on pyramidal cells from mice without whisker trimming, i.e., control (Con). Bottom panels show the images of apical dendrites (left) and basal ones (right) on pyramidal neurons from mice with whisker trimming (WT). B) Statistical analysis illustrates primary processes per 100 μm on apical dendrites from whisker-trimmed mice and controls (n=18, p<0.05). C) illustrates primary processes on basal dendrites from whisker-trimmed mice and control (n=18, p<0.05). D) shows secondary processes on basal dendrites from whisker-trimmed mice and controls (n=18, p<0.01).
