Projections from LH (lateral hypothalamus) to DRN (dorsal raphe nucleus). (A) Schematics of the experimental design for retrograde labeling of LH neurons projecting to the DRN. (B) Coronal section of a mouse brain at the level of the LH shows tdTomato expression following PRV-cre injection in the DRN. (C) Distribution of the tdTomato expressing somata in the LH. AP: anteroposterior. (D) Immunohistochemical labeling of GABAergic neurons.
