Effects of paired associative stimulation (PAS) on the ultra-structure and synaptic structure parameters in the hippocampal CA1 area of rats with cerebral ischemia.

(A) Ultra-structure of hippocampal CA1 area (transmission electron, ×15,000). (B–E) Synaptic structure parameters in the hippocampal CA1 area. The results are expressed as the mean ± SD (n = 30 pieces in each group). *P < 0.05, vs. sham group; #P < 0.05, vs. tMCAO group (one-way analysis of variance followed by Fisher’s least significant difference test). tMCAO: Transient middle cerebral artery occlusion.
