Supplementary Figure 1: Nicotine activates non-catecholaminergic neurons in rostral NTS.
From: GLP-1 acts on habenular avoidance circuits to control nicotine intake
(a) Graphical representation of relative distribution of tyrosine hydroxylase-positive (TH+) neurons in the rostral NTS (rNTS). (b) Representative micrographs of Fos (in red) and TH+ (in green) neurons in the cNTS after nicotine (0.25-1.5 mg/kg) injection. The majority of Fos-positive cells were in non=TH+ cells (identified by white arrows), with few TH+ cells demonstrated Fos immunoreactivity in response to nicotine (identified by yellow arrows).
