Effects of olanzapine and haloperidol on neurogenesis in the dentate gyrus of the hippocampus after the Morris water maze test. (A) Representative photomicrographs of control, MK-801, MK-801+olanzapine, and MK-801+haloperidol groups. The majority of bromodeoxyuridine (BrdU)-labeled cells are located in the subgranular zone of the hippocampal dentate gyrus in the region between the granule cell layer and hilus. (B) Effects of olanzapine and haloperidol on the MK-801-induced decrease in the number of BrdU-labeled cells. Data are expressed as mean±standard error of mean; *p<0.01 vs. control group, ^†p <0.05 vs. MK-801-treated group.
