abnormal dendrite morphology ( J:180581 )
• the basal dendrites of layer V pyramidal neurons grow to the apical side with curling and collaterals from apical trunks show disorientation and winding
• cortical neurons show an increase in the number of primary dendrites
• the highest number of dendrite crossings is found at about 40 um compared to 60-80 um in controls
• the basal dendritic field is further shifted to the apical part of the cell body and to the close part of cell body compared to mutant mice wild-type for Crmp1
