A better understanding of neuroimmune communication is crucial for identifying conserved and divergent mechanisms across ...

What did the very first complex vertebrate brain look like? To find out, scientists turned to an unlikely time traveler: the ...

Archaea are often mistaken as bacteria, given that both are small, single-cell organisms. However, archaea are as genetically different from bacteria as humans are from bacteria. While archaea are ...

Vertebrates have extremely different brain sizes: even with the same body size, brain size can vary a hundredfold. As a rule, mammals and birds have the largest brains in relation to their body size, ...

The researchers from the HiLIFE Institute of Biotechnology, University of Helsinki compared two central bearded dragon lizards (Pogona vitticeps): a normal one and a mutant with no body scales. They ...

Researchers report that ancient viruses may be to thank for myelin -- and, by extension, our large, complex brains. The team found that a retrovirus-derived genetic element or 'retrotransposon' is ...

Researchers have long assumed that a tube in the famous Pikaia fossil ran along the animal’s back. But a new study turned the fossil upside down. By Carl Zimmer Over the past 500 million years, ...

Walking is a complex mechanism involving both automatic processes and conscious control. Its dysfunction can have multiple, sometimes extremely subtle causes, within the motor cortex, brain stem, ...
