CHAPTER 1 Fig. 2 Changes in PCC in the ipsilateral and contralateral side of both striatum (St) and ventral midbrain (VM) after stereotaxic, unilateral (right), intrastriatal injection of 6- OHDA (6 �g in 5 �l of sterile saline containing 0.2% ascorbic acid) to rats. Each point represents the mean ± SD from five animals (n = 5). Asterisks denote values significantly different from the corresponding control (LSD test; p < 0.05). 98
