There is considerable evidence to suggest that amphetamine can improve functional outcome in animal model of stroke, which is involved in the mechanisms of induced axonal growth and reinnervation of brain tissues. In this study we used DTI to assess changes in perilesional tissue integrity after amphetamine treatment in a rat stroke model. We found that FA showed a significantly higher increase under the influence of amphetamine after 25 days.
