Hello and welcome to Grey Matter Hour. I am Fiona Castellan, and for ten years my job was to put people to sleep in a lab and watch what their brains did with the day. This is the show where we take one ordinary thing your brain does and find out why. Today, names and smells. Why can you forget a name before the handshake ends, and yet one whiff of a certain soap puts you back in your grandmother's kitchen? The answer runs through a seahorse-shaped structure behind your ears, a direct wire from the nose, and a small trick I will teach you that genuinely helps with names. Later I will also tell you about a famous memory study that fell apart when people tried to repeat it. You are listening on Witspeak Podcasts. Let us begin.
