Previously, we demonstrated that DH stroke causes delayed ipsilateral cortical atrophy in 3-5 mo C57BL/6 mice at 8 weeks post-surgery, and that atrophy is correlated with a loss of neuronal specific nuclear protein (NeuN)+ cells in the peri-infarct cortex and external capsule [108]. This evidence concerns the gene RBFOX3 and Atrophy.
