How Much of Your Brain Do You Actually Use?

The video explores the complexity of the human brain, debunking the myth that we only use 10% of it. It traces the historical understanding of the brain from ancient times to modern neuroimaging techniques like CT, MRI, EEG, PET, and fMRI. These techniques have shown that we use 100% of our brain, just not all at once. The video concludes by suggesting future research directions in neuroplasticity and memory.
