Trained goldfish showed a remarkable ability to accurately estimate the distance that they had swam. The neural circuits that underpin spatial navigation in mammals, birds, and reptiles are well known ...

Humans use lots of different types of information to make sure we don't get lost. We can look out for familiar landmarks and use our sense of direction, but we can also estimate how far we have walked ...

The neural circuits that underpin spatial navigation in mammals, birds, and reptiles are well known, but it was unclear whether similar structures also existed in fish. This knowledge would allow us ...
