The use of 5-Bromo-2'-deoxyuridine (BrdU), a thymidine analog, permits the following of recently formed cells because it is incorporated into the DNA of dividing cells amid the S stage of the cell cycle. The immunocytochemical examination uncovered a 67% increase in BrdU-labeled cells within the running group, meaning upgraded neurogenesis, which is factually noteworthy as shown by the p-value of 0.0001. The observation that the runner group effectively utilized the running wheels given in their cages relates to the increment in BrdU-labeled cells.
