Can we learn without a brain?

(Image: Pixabay CC0) Some animals do not need a brain to be able to learn. This is what Professor Simon Sprecher of the University of Freiburg has revealed in a study that has just been published. With his team, the biologist taught a sea anemone to adapt its behavior according to past experiences . We spontaneously associate the faculties of learning and memorization with the existence of a brain. Indeed, science already knows a lot about the functions of the different brain areas in humans, mice or insects. But not all animals have a brain. Cnidarians, such as anemones, jellyfish and corals, have a rudimentary nervous system.
