Understanding the Brain: From Ancient Drawings to Modern Neuroscience

The video explores the evolution of understanding the brain's structure and function, from ancient diagrams to modern neuroscience. It highlights the development of the Golgi stain, which allowed the visualization of neurons, and compares it to modern techniques like green fluorescent protein and Brainbow mice. The use of antibodies to study specific brain molecules is also discussed, emphasizing the natural origins of these scientific tools.
