There is a book. It is somewhat outdated, but for people who are interested in some of the growth factor adaptations related to exercise like release of brain drive, neurotrophic factor, and things like that, there is a book.

Why people recommend it

Spark by John J. Ratey and Eric Hagerman is a non-fiction book exploring the connection between exercise, the brain, and neuroplasticity. The book was discussed extensively across several podcast episodes. On The Tim Ferriss Show, Tim Ferriss mentioned the title during conversations with guests like Chris Palmer and in a prior episode with Tony Robbins, noting that while it is somewhat older and parts are outdated, it serves as a valuable resource covering growth factor adaptations, brain-derived neurotrophic factor, and the specific role of physical activity in education and learning. Similarly, on the Huberman Lab podcast, Andrew Huberman frequently cited the work. He highlighted John Ratey as a Harvard psychiatrist and noted that the text stands as an early academic contribution explaining how movement relates to brain plasticity and cognitive function. Huberman also pointed to the author's insights regarding the vital role that play exerts in neuroplasticity and recommended reading from physical books rather than screens to broaden the visual window and improve focus. Additionally, guest Coleman Ruiz referenced Ratey's anecdotes from the volume while discussing physical and emotional challenges during an appearance on Huberman Lab. Overall, the speakers characterized the publication as an influential, albeit aging, roadmap linking cardiovascular health to cognitive vitality.

“There is a bit dated probably, but there's a book called Spark, which also goes into a lot of BDNF, and a lot of the circuitry and biochemical reasons for exercise for this explicit purpose.”
