(a) The hippocampal region of the adult human brain immunoperoxidase-stained for the neuronal marker NeuN. 
(b) The hippocampal dentate gyrus granule cell layer (GCL) visualized with immunoperoxidase staining for NeuN. 
(c) Differential interference contrast photomicrograph showing BrdU-labeled nuclei (arrows) in the dentate granule cell layer                             (GCL). 
(d) Differential interference contrast photomicrograph showing a BrdU-labeled nucleus (arrow) in the human dentate GCL. BrdU-positive nuclei have a rounded appearance and resemble the chromatin structure of mature granule cells and are found within the granule cell layer. 
(e) Differential interference contrast photomicrograph showing BrdU-positive cells (arrows) adjacent to the ependymal lining in the subventricular zone of the human caudate nucleus. Cells with elongated nuclei resembling migrating cells are in the rat subventricular zone (SVZ). 
(f) Differential interference contrast photomicrograph showing BrdU-positive cells (arrows) with round to elongated nuclei in the subventricular zone of the human caudate nucleus. 
All scale bars represent 50 microns.

Fig. II: Quantitation of newly generated cells in the adult human hippocampus. 

The density of BrdU immunoperoxidase-stained cells in the subgranular zone (SGC) (a) and the granule cell layer (GCL) (b) and the hilus (c) was determined in 5 to 7 sections per patient (mean number of BrdU-positive cells per mm3 sample volume  s.e.m.) The corresponding patient's age at the time of death and interval as BrdU infusion are given for each BrdU-treated patient (n = 5).

Methods: 
Postmortem tissue from the hippocampus and the subventricular zone of caudate nucleus was obtained from cancer patients (n = 5) who received one intravenous infusion (250 mg; 2.5 mg/ml, 100 ml) of bromodeoxyuridine (BrdU) for diagnostic               purposes. One patient diagnosed with a similar type and location of cancer, but without BrdU treatment, was included as a control.

**Notes:**
Running significantly increased cell proliferation/neurogenesis in the dentate gyrus of mice.

(a) Total number of BrdU-positive cells per dentate gyrus one day after the last BrdU injection, to estimate ongoing proliferation. Significantly more cells were labeled in the runners as compared to the other groups. * p < 0.02. 

Enrichment and running significantly increased the survival of newborn cells.

(b) Total number of BrdU-positive cells per dentate gyrus four weeks after the last BrdU injection, to estimate survival of labeled cells. Enrichment and running significantly increased the survival of newborn cells. *p < 0.02.
