Jellyfish are not the 'simple creatures' once thought: New study may change an understanding of our own brains

Jellyfish could be much smarter than scientists previously thought, asserts a new study published in the journal Current Biology. Here's what researchers discovered about the workings of their brains.

Scientists say their findings change the fundamental understanding of the brain — and could reveal more about human cognitive functions and the process of dementia. "For fundamental neuroscience, this is pretty big news. It provides a new perspective on what can be done with a simple nervous system." "Jellyfish have a much more refined ability to learn — and they can actually learn from their mistakes." The findings contradict previous scientific perceptions of what animals with simple nervous systems are capable of.  Melissa Rudy is health editor and a member of the lifestyle team at Fox News Digital. 

Jellyfish have been around for over 500 million years — yet until now, they've been thought of as simple creatures with very limited learning abilities.
