For over half a billion years, evolution has sculpted the nervous systems of bilaterian animals, equipping them with ...

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 ...

The nervous system has two major parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The central system is the primary command center for the body, and is comprised of the ...

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 ...

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 ...

In order for your body to work properly, your nervous system needs to be working properly. Your nervous system is responsible for helping your brain communicate with your body and helping your body ...

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 ...
