For over half a billion years, evolution has sculpted the nervous systems of bilaterian animals, equipping them with remarkable capabilities to process information, coordinate movements, and respond ...

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 ...

Octopuses are not much like humans — they are invertebrates with eight arms, and more closely related to clams and snails. Still, they have evolved complex nervous systems with as many neurons as in ...

Starfish, also known as sea stars, are equipped with an almost alien-like anatomy. Despite lacking a brain, blood, and ...

The authors noted symmetrical stains along the creature's midline that resembled nervous system structures found in some modern arthropods, including horseshoe crabs, spiders and scorpions. "The ...

Injured axons instruct Schwann cells to build specialized actin spheres to break down and remove axon fragments, thereby starting the regeneration process. Damaged peripheral nerves can regenerate ...

Glial cells, also known as neuroglia, are non-neuronal cells that play a crucial role in various neurophysiological processes. They not only support nervous system structures but also contribute to ...

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 ...

Interpretation of clinical findings of BPI in newborns depends on knowledge of peripheral nervous system (PNS) structures and physiology. All nervous system structures originate from the embryonic ...
