Fig. 5. Quantification of dendritic parameters of multipolar interneurons from layers II/III, V and VI after overexpression of EGFP, BDNF/EGFP and NT4/5/EGFP during the later time window, DIV 5-10. For direct comparison, dendritic parameters of biocytin-filled multipolar interneurons from adult spontaneously active OTC were included. The neurotrophin transfectants at 10 DIV displayed number of segments and maximum branch orders close to adult interneurons, whereas dendritic length was still far from being mature. *=P<0.05; **=P<0.01; ***=P<0.001. The numbers in the bars represent the number of dendrites analyzed.
