There is a useful way of framing biological questions that makes familiar things strange, and sleep is the clearest case. The framing is to ask what a trait costs, and then ask what it must deliver to ...

Animal models have significantly increased our understanding of nervous system disorders. Yet, in spite of these advances, there still remains a large gap in treatment options that are high in ...

Researchers propose that placozoans, one of the simplest kinds of animals, may contain the blueprint for the neurons of more complex creatures. By Sam Jones For hundreds of millions of years, ...

Ask someone to think of an animal, and chances are they’ll come up with one of our relatives among the mammals. A few people might go further afield and mention other vertebrates, like birds and fish.

An international team of scientists has uncovered a fascinating piece of the evolutionary puzzle: how the ventral nerve cord, a key component of the central nervous system, evolved in ecdysozoan ...

Learn about the wide-ranging Ecdysozoa group of animals and how scientists solved the curious case of their nervous systems' structure. With so many elusive creatures occupying the forgotten corners ...

A new study has rewritten the conventionally understood evolutionary history of certain ion channels -- proteins critical for electrical signaling in the nervous system. The study shows that the ...
