Fig. 5.

Top, left. Autoradiograms and line graph showing the changing expression of BDNF after striatal injury. The line graph shows striatal BDNF mRNA expression (counts per minute/square millimeter) 0, 7, 30, and 120 d after injury in ipsilateral and contralateral striatum (n = 4 at each time point). All values are mean ± SEM. The autoradiographs are representative sections at key time points showing the changing expression of BDNF. Note that the expression of BDNF at 7 d is relatively widespread, whereas at 30 d it is restricted to the immediate periwound area. Increasing signal intensity is represented by color change fromblue to red. *p ≤ 0.0005; $p ≤ 0.05.
