Explore neuroscientist Michael Merzenich's groundbreaking research on brain plasticity in this 23-minute TED Talk. Discover how the brain's ability to actively rewire itself can be harnessed to enhance skills and recover lost function. Learn about the two great epochs of brain plasticity, the enlargement of specific brain surface zones induced by training, and learning-induced changes in spatial filters. Delve into the rehabilitative extensions of brain plasticity research, including advances in standardized language battery scores and large-scale improvements resulting from neuroscience-based training. Gain insights into how these findings relate to aging and potential applications for personal development.
