Fig 4. The effect of MS 0.9% NaCl injection on VNS-induced HPC field potential and related power-frequency (FFT) histogram.

Fig 4

(A) VNS is marked with a horizontal line. The parameters of VNS are marked below this line. Arrows indicate the power-frequency histograms calculated from the analog examples of hippocampal field potentials taken pre-injection of 0.9% NaCl (control) and 15 min post-injection of 0.9% NaCl during 10 s VNS. Calibration: 1 s, 150 μV. (B) Statistical analysis (Mann-Whitney U test) of mean ± SEM power and frequency (VNS(1) vs VNS(2)).
