Faculty research: Collision detection center in the tadpole brain

It was known for some time that Xenopus tadpoles try to avoid collisions with objects that approach them, but until now it was not quite clear what part of the brain detects potential collisions and makes the tadpole change its swimming trajectory. In this study Dr. Arseny Khakhalin shows that most likely this calculation happens in the midbrain region called the optic tectum.
