Abstract

Numerous studies have shown that transcranial magnetic stimulation (TMS) can improve cognitive function and symptoms in patients with major depressive disorder (MDD). However, little research has applied TMS to patients with stress disorder, and its mechanism remains to be elucidated. In this study, we established a stress model in non-human primates (NHP) to observe changes in memory and behavior following repetitive transcranial magnetic stimulation (rTMS) intervention, and further explored the effects of rTMS on neuronal firing. We found that rTMS promoted the recovery of memory and behavior in cynomolgus monkeys with stress disorder, which may be associated with alterations in neuronal firing frequency. Upon further exploration and research, we found that the 10 Hz protocol elicited a higher proportion of neurons with increased firing rates compared to the 1 Hz protocol. The 1 Hz protocol induced a significant relative increase in firing rates that was predominantly driven by putative excitatory neurons, in which the relative increase was significantly greater than that of the 10 Hz group.
