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 ...

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

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 and are capable of a wide ...

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 ...

A popular image shared by science-focused social media accounts is that of an image labeled as some variation on "the complete human nervous system dissection" or "a fully dissected nervous system." ...

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 ...

We’ve turned survival responses into a black-and-white idea: pathology or wisdom. This is what we miss when we do that, and ...
