Dive deep into the mysterious world of neuroscience in this mind-bending episode of What Is! We explore Nano-MIND, a technology that brings us closer to controlling the brain wirelessly and remotely. Imagine a future where emotions, decisions, and behaviors can be precisely modulated - without the need for implants. Join us as we discuss how this magnetogenetic approach could revolutionize treatments for neurological disorders, enhance brain-computer interfaces, reshape how we understand human autonomy, and also bring ethical dilemmas.
