Spider Cognition: How Tiny Brains Do Mighty Things

An in-depth look at spider cognition, how they filter information, and how they do seemingly brilliant things with only a handful of neurons. To explore the mysteries of spider brains, I interviewed Dr. Ximena Nelson and Dr. Massimo de Agro, who have both studied spider cognition. I discuss spider eyes, spiders' numerical ability, navigation, and recognition of living things - among other topics.
