Number of DOR labeled cells in dentate gyrus

CIS Group	Total hilus	crest	central	Dorsal blade
Male Sal	23.5 ± 1.72	20.8 ± 4.73	20.0 ± 7.53	21.1 ± 4.77
Male Oxy	27.5 ± 2.80	22.5 ± 4.23	21.7 ± 2.11	22.2 ± 4.36
Female Sal	25.8 ± 3.11	20.8 ± 5.23	15.8 ± 4.36	22.2 ± 1.41
Female Oxy	24.8 ± 3.33	22.5 ± 3.82	14.2 ± 3.52	22.8 ± 3.80

The area of the hilus was measured using the granule cell layer and CA3 pyramidal cell layer as borders, and the number of cells per mm² was then calculated. The number of cells in the crest, central hilus and dorsal blade of the hilus was determined by randomly placing a 200 μm² rectangle over these regions, using the granule cell layer as a guide.
