Comparisons with amphioxus and tunicates have indicated that the vertebrate brain and peripheral nervous system were elaborated from those of an ancestral chordate with a bipartite brain ...

Researchers from the European Molecular Biology Laboratory (EMBL) in Heidelberg now reveal that the vertebrate nervous system is probably much older than expected. The study, which is published in ...

Ultimately, Hale believes that in addition to illuminating the unexpected ways an invertebrate species might design a nervous system, understanding these systems can aid in the development of new ...

But scientists have been keen to find out just how far back they can trace key developments, such as the signals that spurred our central nervous system to develop. "The vertebrate brain is really ...

But unlike their vertebrate cousins ... bypassing the parts of the nervous system connected with the conscious perception of pain. When we scald our hand, for example, we immediately — and ...

In the nervous system, WNT signalling also regulates neuronal ... dendrite morphogenesis and synapse formation. Studies, from invertebrates to mammals, have led to a considerable understanding ...

Previously, scientists were unsure exactly how the ventral nerve cord (a vital component of invertebrates’ central nervous system) developed in ecdysozoans. However, a close look at Cambrian-age (541 ...

The hydra is a tiny freshwater invertebrate, which is related to ... can regrow all tissue types and even a new central nervous system. Humans, on the other hand, struggle to repair any tissue ...
