Desynchronized theta activities between the BLA and ACC in cisplatin rats. a Representative traces of spontaneous theta band field potential in the BLA (black line) and ACC (blue line) in control (left) and cisplatin (right) rats. b Time-varying power spectra of BLA (upper) and ACC (bottom) LFPθs in control and cisplatin rats. c The averaged cross-correlograms of control and cisplatin rats for both spontaneous activity and during visceral pain stimulation (60 mmHg CRD). d Statistical analysis revealed that the cross-correlation value (the second positive peak) was decreased in spontaneous theta activity in cisplatin-treated rats compared with control group. Meanwhile, in control rats, CRD significantly enhanced the correlation value when compared with spontaneous activity. In cisplatin rats there was no changing during CRD stimuli compared with resting state. Data are expressed as mean ± SEM. *, # p < 0.05
