the exercise had prompted increased production of the hormone.
Most of the animals also had a plethora of new neurons in the hippocampus, a portion of the brain associated with learning and memory. Unexpectedly, however, the animals in this experiment that could not use the DHT in their brains did not experience enhanced neurogenesis. They exercised just as the other animals did, but their brains did not benefit in the same way.
This tells us that the uptake of DHT in the brain after exercise “appears to be a necessary step in achieving adult hippocampal neurogenesis,” Dr. McEwen says.
In essence, exercise prompts the production of more DHT. And more DHT helps to create more new brain cells.

Something to note if our brains are unable to take in correct amounts of DHT we then struggle to achieve neurogenesis.
If you guys are able to jog like in the experiment then it could help PFS.
