Lecture with Shelley Halpain, Ph.D., University of California, San Diego
Just as recent advances in whole-brain imaging now allow us to watch our minds at work, advances in cellular imaging now enable scientists to watch how the brain wires itself up during development. There is surprisingly a lot going on in there, as brain cells (“neurons”) harness their internal machinery to create movements from subtle to supersize.
Physical changes in brain architecture not only underlie learning and memory, but occur throughout the lifespan. Witness time-lapse “movies” of living neurons engaged in building neural circuits.
