“…In rats, peripheral administration of LiCl induces cFos neuronal activity in the IPBN, the AP and the NTS [726,729] with remarkable overlap in the cFos activity pattern induced by centrally administered GLP-1 [726]. Apart from inducing cFos activity in the same brain areas [696,726,730], LiCl and central GLP-1R agonism both decrease locomotor activity [668,731], slow GI motility and gastric emptying [573,732], reduce body temperature [732,733], and induce adverse gastrointestinal effects including nausea, emesis, and taste avoidance [696,[724], [725], [726],[734], [735], [736], [737]]. Selective ablation of NTS PPG neurons prevents stress-induced hyperphagia in mice but has no effect on long-term ad libitum food intake, body weight, or glucose tolerance [90].…”
