Additionally, non-secretory PVN neurons may participate in ghrelin effects on other physiological functions such as anxiety-like behavior (Currie et al., 2012; Wauson et al., 2015) and feeding (Wren et al., 2001; Melis et al., 2002; Olszewski et al., 2003; Shrestha et al., 2004) which are increased by intra-PVN administration of ghrelin. Here, GHRL is linked to Anxiety.
