Figure 10

Location of electrode tip at 5 months postinjury without prior MRI analysis. Photomicrographs of thionine-stained coronal brain sections of 4 animals; (A) #1019, (B) #1139, (C) #1158 and (D) #1036 in the MRI cohort with electrode implantations at 5 months after TBI. Left panels: MRI-guided placement of the posterior cortical electrode. Note that all electrodes are within the perilesional cortex. Right panels: The location of the electrode tip (arrow), if the electrode was implanted according to the targeted atlas-based coordinates (−7.56 mm from bregma, 4 mm from midline, 1.8 mm from the surface of the brain). Note that in all rats except 1019, the electrode tip ended in the lesion cavity. Table 2 summarizes the locations for all cases. Scale bar = 2 mm.
