Researchers discover an 'all-body brain' in sea urchins
An international team of researchers, including scientists from the Museum für Naturkunde Berlin, has uncovered a surprisingly complex nervous system in sea urchins. The animals appear to possess an "all-body brain" whose genetic organization resembles that of the vertebrate brain. The team also identified light-sensitive cells distributed across the entire body—comparable to structures found in the human retina.
This Sea Creature Has a Brain in Every Part of Its Body
A groundbreaking new study has revealed that sea urchins, a fascinating sea creature, have a surprisingly complex nervous system, functioning like a brain spread all over their bodies. These creatures, along with other echinoderms like starfish and sea cucumbers, undergo major physical changes as they mature. While they start out symmetrical, they eventually develop a unique radial symmetry, setting them apart from most animals with bilateral sy…
Exercise: good for the body and brain
by Kerrie Meyler Exercise is good for the body – it tones the legs, can build bigger biceps, and strengthens the heart. But of all the body parts that benefit from a good workout, the biggest winner may be the brain. Older people who continue exercising regularly experience a slower rate of mental decline (National Institutes of Health, 2017). Physical fitness directly affects our minds, playing a crucial role in the way the brain develops and f…
