Tmaze movie

Video of worms in a T-maze. Favored/superior food is at the end of the left arm. Non-favored/inferior food is at the end of the right arm. The video shows 15 min of real-time behavior in 5 sec, so time is speeded-up by a factor of 180. Most worms are immediately drawn to superior food, but some try the inferior before settling on the superior food. Credit: Aaron Schatz (CC BY-SA)
