| Type | MGI:General | Description | dendrites from pyramidal neurons have an abnormal pattern with poor alignment and are wavier in appearance than the straight apical dendrites of wild-type mice the mean linearity index for apical dendrites is 1.3 +/- 0.05 compared to 1.06 +/- 0.01 the number of branches on apical dendrites of CA1 pyramidal cells is decreased by about 25% for primary dendrites and by about 50% for secondary dendrites total dendritic length is also reduced by about a third lengths of mushroom and finger spines of pyramidal cells is significantly reduced |
