Journal Article: The role of the basal ganglia in category learning (2006)

Abstract:
C
ategorization is the act of responding differently to objects or events in separate classes or categories. It is a vitally important skill that allows us to approach friend and escape foe, to find food and avoid toxin. Every organism must have some categorization ability. Even bacteria categorize. For example, the bacterium e. coli tumbles randomly until it encounters a substance that it categorizes as a nutrient. It then suppresses its tumbling behavior and swims up the concentration gradient in search of the nutrient’s source.
