Medial septal cholinergic mediation of hippocampal theta rhythm induced by vagal nerve stimulation
Fig 6
The effect of MS atropine injection on VNS-induced HPC field potential and related power-frequency (FFT) histogram.
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 atropine (control), 15 and 180 min post-injection of atropine during 10 s VNS. Calibration: 1s, 150 μV.
