Title

The impact of repetitive transcranial magnetic stimulation and fluoxetine on the brain lipidome in a rat model of chronic unpredictable stress

Overall design

In this study, the antidepressive effects of repetitive transcranial magnetic stimulation (rTMS) and fluoxetine treatments were assessed using a chronic unpredictable stress (CUS) model in rats. Changes in lipid composition in the hippocampus and prefrontal cortex (PFC) were evaluated using a mass spectrometry-based lipidomic approach. Sprague-Dawley rats were divided into the following 4 groups (n = 8 in each group): (1) control group (no stress, sham rTMS and vehicle injections), (2) CUS group (stress, sham rTMS and vehicle injections), (3) CUS + rTMS group (stress, real rTMS treatment and vehicle injections), and (4) CUS + fluoxetine group (stress, sham rTMS treatment and fluoxetine injections, 10 mg/kg). The CUS stress procedure lasted for 4 weeks, and rTMS and fluoxetine were administered for a week after stress.
