Fig. 9From: Stress-induced microglial activation occurs through β-adrenergic receptor: noradrenaline as a key neurotransmitter in microglial activationa A schematic depiction of the α-blocker treatment protocol with prazosin and yohimbine. b Plasma corticosterone levels (ng/mL) of saline- and α-blocker-treated rats in acute RS. The asterisks indicate a statistical difference between saline- and yohimbine-treated rats following acute RS at each time point (*p < 0.05, **p < 0.01, n = 4).
