The claims behind it
AAV-retro-Cre injected into the caudolateral PAG together with a Cre-dependent fluorophore in the amygdala labelled cell bodies in the central-medial boundary zone, showing these neurons project to the PAG; about 92% of them expressed VGAT.

tdTomato/ChR2 labelling of PAG-projecting amygdalar central-medial boundary neurons revealed dense axon terminal fields in the caudolateral PAG overlapping those of POAPAG neurons.

Cre-dependent tdTomato injected into the amygdala of Esr1-Cre mice revealed labeled axons in the caudolateral PAG region containing PAG-USV neurons.

Injecting AAVretro-Cre into caudolateral PAG plus Cre-dependent virus in the amygdala labeled PAG-projecting neurons in the AmgC/M but not the CeA of female mice; these neurons were all VGAT-positive.
