Neuroscientist Reveals the Best Exercise for Growing New Brain Cells

For years, it was believed that once you reach adulthood, your brain becomes static without the formation of new brain cells. However, scientific research has revealed the opposite, according to the Times of India.

Dr. Robert Louv points out that modern neuroscience has turned this idea on its head. In fact, numerous published studies show that adult mammals (including humans, under certain conditions) can experience the growth of new neurons, particularly in an area called the hippocampus, which is crucial for memory formation, learning, and emotional regulation. With aging, neuron loss, synaptic pruning, and decreased plasticity in brain regions like the hippocampus significantly contribute to cognitive decline, increasing the risk of disorders like Alzheimer's disease.

Brain Fertilizer

When muscles and other tissues are active during exercise, the body releases a protein called brain-derived neurotrophic factor (BDNF). Brain-derived neurotrophic factor (BDNF) is sometimes called the "fertilizer" of the brain because it facilitates the growth of new neurons, supports dendritic branching (connections between neurons), and helps existing neurons survive and function properly. BDNF has been closely linked to the formation of healthy neurons in the hippocampus.

Exercise Matters

Exercise helps build muscle and can also promote neurogenesis. Dr. Love emphasizes that not all exercise is equal in promoting BDNF release and stimulating neurogenesis. Dr. Love says he recently attended a neuroscience conference where Dr. Austin Perlmutter presented evidence that resistance training (weight lifting, bodyweight exercises, etc.) may be superior to aerobic training in some respects when the goal is to release BDNF and protect neurons, especially in older adults or those at risk for Alzheimer's disease.

Resistance Training

Studies have also shown a positive effect of resistance training on overall cognitive development. A 2023 scientific review concluded that resistance training significantly increases levels of brain-derived neurotrophic factor (BDNF) in humans, although there is variability depending on training intensity, duration, and individual differences.

Alzheimer's Prevention

Higher levels of BDNF have been associated with a reduced risk of Alzheimer's disease and slower cognitive decline. Although BDNF does not "cure" Alzheimer's disease, boosting it through exercise is one of the most powerful non-drug strategies available.

Reducing Amyloid Burden

Resistance training is being specifically studied for its effects on reducing amyloid burden, improving neuronal survival, reducing inflammation, and preserving hippocampal volume. Incorporating strength training can improve mood regulation, increase resilience to stress, and support overall cognitive performance as we age. It also improves sleep, regulates blood sugar, improves metabolic health, supports cardiovascular function, and enhances long-term brain plasticity.
