Treatment with GTA improved long-term neurological function after cerebral ischemia. A The representative image of TTC staining for infarct size on day 7 after cerebral ischemia. B Quantification of relative infarct size on day 7 after cerebral ischemia. C The neurological defect score on day 7 after cerebral ischemia. D Nissl staining on day 30 after cerebral ischemia. E Brain atrophy analysis based on D. F The recovery of forepaw strength over 30 days after cerebral ischemia. G and H Contact time and contact asymmetry over 30 days after cerebral ischemia. I and J, Removal time and removal asymmetry over 30 days after cerebral ischemia. n = 8, compared with MCAO, *P < 0.05, **P < 0.01. B and E were analyzed by Student t-test, C was analyzed by Kruskal–Wallis test, F–J were analyzed by two-way ANOVA and multiple comparisons corrected with Tukey method
