Have you ever wondered why you can forget where you put your shoes, but you never forget how to ride a bike? Your brain is the ultimate supercomputer! In fact, it can hold about 2.5 million gigabytes of information—that is like recording three million hours of your favorite TV shows! Join Mira and Finn on Science is Not Boring as they uncover the amazing secrets of how our memories actually work. Did you know that every time you learn something new, your brain literally grows new physical branches? We will explore how a clever scientist used a giant, squishy sea slug to prove it! You will also meet the most famous patient in neuroscience history, Patient H.M., who helped doctors discover that we actually have two completely different memory systems. Plus, find out the sneaky biological reason why a simple smell, like baking cookies or rain on the sidewalk, can instantly transport you back in time! Get ready to build some brand new brain connections and discover the incredible science happening right inside your very own head!
