Unfortunately, after publication of this article [1], it was noticed that Fig. 1b (Fig. 1 here) is incorrect. The corrected figure can be seen below.

Time course of MRI changes following intrastriatal microinjection of 100 ng/μl IL-1β. ADC changes determined by thresholding. Mean ADC (error bars indicate a 1 SD) within the ipsilateral or contralateral striatum. Statistical significance indicated by *** p < 0.001, * p < 0.05; paired t-test, † p < 0.05; unpaired t-test and ▲▲▲ p < 0.001, ▲▲ p < 0.01; one-way ANOVA, post-testing using Bonferroni multiple comparisons test, with respect to the ADC of the IL-1β-injected hemisphere at 2.5 h
