a
GH cells: a diffuse population of neurons that were observed in the forebrain, lateral to the anterior olfactory nucleus and piriform cortex. This GH-IR-displaying region was designated as GH cells in our table because they did not fall into a predefined brain nucleus according to a published report (22).
