Fig. 5From: Peripheral and central compensatory mechanisms for impaired vagus nerve function during peripheral immune activationDopamine to DOPAC utilization index. CNT naive control, SH sham surgery, VG subdiaphragmatic vagotomy, NaCl single intraperitoneal vehicle injection, LPS single intraperitoneal LPS injection. Vagotomy itself elevate DOPAC/DA ratio in amygdala. Again this effect is not observed during inflammation. However, we observed an elevated DOPAC/DA ratio in hypothalamus of vagotomized rats during inflammation. Details in textBack to article page
