Transcutaneous Auricular Vagus Nerve Stimulation Triggers Melatonin Secretion and Is Antidepressive in Zucker Diabetic Fatty Rats
Figure 4
Correlation of melatonin concentration and immobility time in FST on day 35.
Linear regression analysis found a strong negative correlation between the plasma melatonin concentration and the immobility time in forced swimming test in ZDF (R = −0.544) but not ZL rats (R = 0.254, also see Table 3).
