“…To elucidate which subpopulations in LH GABA neurons exclusively contribute to seeking and/or consummatory behaviours, several studies have been dedicated to identifying subpopulations and neural circuits 10,16,17,20 . LH leptin receptor expressing (LH LepR ) neurons are subpopulation of LH GABA neurons and has been reported to be associated with eating 10,16,[21][22][23] . However, the role of LH LepR neurons is controversial; no effect on eating 10,24 , decreased eating 16 , decreased eating after leptin treatment in the LH 22 , and increased eating by LH LepR -Ventrolateral Periaqueductal Grey (vlPAG) circuit 23 .…”
