FIG. 3.

(A) Low manganese ion (Mn²⁺) dose (group 2) T2 maps and T1-weighted images 2 h after traumatic brain injury (TBI) and 3 h after Mn²⁺ administration from the same animal. T2 maps showed no changes while T1-weighted images had sufficient signal enhancement similar to the high dose in the lateral ventricles (white arrows) and the apparent lesion (white box). (B) Group-averaged forelimb asymmetry and (C) foot fault scores at different time points. Error bars are standard error of the mean. N=6 for the low dose (group 2). N=6 for the vehicle (group 3). The scale bar indicates T2 of 0–100 msec. MnCl₂, manganese chloride.
