Jellyfish Study Challenges Understanding of Brain Function

A new study from the University of Copenhagen suggests that jellyfish, specifically the poisonous Caribbean box jellyfish, have a much more advanced ability to learn than previously thought, despite having only 1,000 nerve cells and no centralized brain. The research challenges the prevailing scientific opinion that more advanced nervous systems equate to higher learning potential. The findings could provide insights into human cognitive functions and the process of dementia. The study also offers opportunities to study the precise changes that occur in nerve cells during advanced learning, potentially leading to a better understanding of memory and the development of treatments for dementia.
