In vivo DTI detected brain structural changes in cocaine administered mice. Our findings indicated demyelination in white matter structures in chronic administration in mice. Results also indicated the involvement of gray matter. 
Figure 3: Change in DT measures at different time points. Blue, green, and orange colors denote values at week 0, week 1, and week 4 respectively. Statistically significant change is represented by symbol as ●: (W0~W1), ◆: (W1~W4), *: (W0~W4).
