We previously showed that, epileptic rodents (a epilepsy model introduced by Kainic acids) display disturbed corpus callosum shown by reduced fractional anisotropy (FA) value with diffusion tensor imaging (DTI), however, we did not check the expression of RhoA or ROCK expression or activity in these rodents(Liu et al. 2016). The gene discussed is RHOA; the disease is epilepsy.
