Jellyfish show how you don ’t need a brain to learn, say researchers

Adjustment of behaviour shown in study suggests learning is integral function of neuronsJellyfish change their behaviour based on past experiences, researchers have revealed, in a study that suggests learning could be a fundamental property of the way nerve cells work.Unlike humans, jellyfish do not have a central brain. However, box jellyfish have clusters of neurons associated with the creatures ’ eye-like structures, known as rhopalia, with this system acting as the visual information processing centre.Continue reading...
