RBFOX3 and ischemia: In the ND-ischemia group, NeuN+ CA1 pyramidal cells were not significantly altered until 2 days after tGCI (Figure 2Ab,Ac); however, a significant loss of NeuN+ CA1 pyramidal cells was observed 5 days after tGCI (Figure 2Ad): the mean number of the NeuN+ pyramidal cells was 82.3 ± 2.2 cells/250 × 250 μm (Figure 2C).
