Figure 3

Enriched environment (EE) improved the number of ipsilateral and contralateral synapses after permanent middle cerebral artery occlusion (pMCAO). (A) Electron microscopy images of hippocampus CA3 showing the ipsilateral and the contralateral synapses in the sham, standard housing (SH), and EE groups. (B) Bar graph indicates the number of bilateral synapses in the sham, SH, and EE groups. Data are expressed as mean ± SEM, n = 8 per group. *P < 0.05, the EE group vs. the SH group in the ipsilateral. #P < 0.05, the SH group vs. the sham group in the ipsilateral. **P < 0.05, the EE group vs. the SH group in the contralateral. ##P < 0.05, ipsilateral vs. contralateral in SH group.
