Retooling Our Brains

The transcript discusses how tool use, such as tennis rackets, affects brain representation, making tools feel like extensions of the body. Experiments show athletes perceive tools as part of their body. Avatars in experiments also alter brain representation. Smartphones have become integral to culture, affecting brain adaptation. The internet and other media have significantly influenced brain evolution.
