It was previously thought that learning behaviours only applied to animals with complex brain and nervous systems, but a new study has proven that this may also occur in individual cells. As a ...

Researchers propose that placozoans, one of the simplest kinds of animals, may contain the blueprint for the neurons of more complex creatures.

But their mostly see-through bodies cloak a nervous system unlike that of any other known animal, researchers report in the April 21 Science.

New animal family tree raises questions about the origin of nervous systems Sponges are more closely related to us than some animals with a nervous system.

Robots are useful tools for studying the nervous system and its control of body mechanics because they can be used to perform experiments that would be difficult to perform with an animal. For example ...

Strange sea creatures called ctenophores have a fused nerve net where scientists expected to see synapses. Did they evolve their nervous system separately from other animals?

These fossils include representatives of the early-evolving Scalidophora, a subgroup of Ecdysozoa, offering a rare glimpse into the nervous system architecture of ancient animals.

Almost all eukaryotic organisms, from plants and animals to fungi, can't survive without mitochondria, which generate chemical energy using oxygen. However, a new study by Lukáš Novák and ...

Almost all eukaryotic organisms, from plants and animals to fungi, can’t survive without mitochondria – the “powerhouses of the cell,” which generate chemical energy using ...
