Comparison of synaptic parameters in aged high frequency-repetitive transcranial magnetic stimulation (HF-rTMS) groups.
| Aged sham | 5 Hz rTMS | 25 Hz rTMS | |
|---|---|---|---|
| Number of counted synapses | 78 | 53 | 52 |
| Number and ratio of perforated synapse | 18 (23.08%) | 14 (26.42%) | 11 (21.15%) |
| Thickness of PSD (nm) | 48.131 ± 2.08 | 54.84 ± 1.25* | 52.82 ± 0.90 |
| Synaptic cleft width (nm) | 15.82 ± 0.85 | 14.88 ± 0.94* | 15.59 ± 0.54# |
| Synaptic curvature | 1.0634 ± 0.0084 | 1.0653 ± 0.0135 | 1.0674 ± 0.0047 |
Data were shown as mean ± SEM; *P < 0.05 vs. aged sham group, #P < 0.05 vs. 5 Hz rTMS group.
