Fig. 3. The later time window: quantification of dendritic length and number of
segments for apical and basal dendrites of pyramidal neurons in layers II/III,
V and VI after overexpression of EGFP, BDNF/EGFP and NT4/5/EGFP.
*=P<0.05; **=P<0.01, Mann-Whitney-U-tests versus EGFP
control. The numbers in the bars represent the number of dendrites analyzed.
For apical dendrites, they equal the number of neurons analyzed. See also
Table 1 for total basal
dendritic length and segment numbers.
