In jellyfish and sea anemones, neurons accumulate DNA damage while animals are awake and repair that damage during sleep.

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 ...

Some very diverse neurological systems have evolved in animals, like those carried by cephalopods, compared to those found in humans. But scientists have now found an interesting commonality: many ...

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 ...

When anxiety spikes, the nervous system can shift into fight-or-flight in seconds, but it can also be guided back toward ...

Many people are familiar with oncogenes - genes long known to be involved in cancers in humans, such as the gene "Src." What's less widely understood is that oncogenes didn't evolve just to cause ...

The first stem cell culture method that produces a full model of the early stages of the human central nervous system has been developed by a team of engineers and biologists at the University of ...

The autonomic nervous system (ANS) plays a pivotal role in regulating involuntary bodily functions that are essential for survival, including cardiovascular and respiratory control. In preterm infants ...

For hundreds of millions of years, pancake-shaped animals the size of a needle tip have been roving the seas with an appetite for tasty microbes and algae. They’re called placozoans, and are among the ...

Your sympathetic nervous system is one of the branches of your autonomic nervous system. It controls functions under unconscious control related to “fight or flight.” Your nervous system plays a ...
