The synchronization of theta activities between the ACC and the BLA increased following VNS.
(a) Two minutes colored power spectra of LFPs in the ACC and the BLA show synchronized theta oscillations after VNS. (b) The averaged cross-correlograms before and after VNS. (c) The second positive peaks of the cross-correlograms which are shown in (b), which corresponds to the theta band activity. (d) Histograms showing the averaged cross correlation value before and after VNS during spontaneous activity. Theta band correlation increased following VNS. Results are presented as mean ± SEM, n = 6. Statistical significance was determined by student t-test, ***p < 0.0001.
