Neurogenesis 101

What is Neurogenesis?

Neurogenesis is the process by which the brain creates new neurons. Neuroplasticity, on the other hand, refers to the formation of new pathways and connections between existing or newly formed neurons.

"While most brains have the ability to develop new cells, the current goal for science is to determine the best methods to enhance this process," says Dr. Rudolph Tanzi, a neuroscientist and co-director of the McCance Center for Brain Health at Harvard-affiliated Massachusetts General Hospital.

Why is Neurogenesis Important?

Neurogenesis is crucial because it is linked to key cognitive functions such as memory, mood regulation, and cognitive flexibility. It also helps increase resistance to neurodegenerative diseases.

How to Promote Neurogenesis?

Several aspects of daily life influence the production of new neurons. Key factors that promote neurogenesis include:

Following the Harvard SHIELD method can also help promote brain health.

The Role of Aerobic Exercise

Regular aerobic activity is particularly beneficial for inducing neurogenesis. But how can you tell if you’re engaging in aerobic exercise?Aerobic and anaerobic exercises differ in terms of intensity and muscle fibers used. Aerobic exercise, which means "with oxygen," involves activities that increase the heart rate (HR), boost blood flow, and enhance the delivery of oxygen to both muscles and the brain. This improves the heart’s output and the muscles' ability to utilize oxygen from the blood.

You can participate in aerobic activities using cardio equipment or by going for a walk or jog.
