Comparison of a single versus repeated magnetic facial nerve stimulation on cerebral blood flow in pigs. Repeated stimulation at 1.9 Tesla power for 2 min; single stimulation at 1.9 Tesla power for 2 min; 1.0 Tesla power for 1 min (“low stim”); and 0.1 Tesla power for 30 s (“sham stim”). BL, baseline. A paired t test demonstrated a significant effect of single and repeated stimulation at 1.9 Tesla power for 2 min versus sham and low stimulation (P < 0.01). Mean ± SE, n = 3 per group
