The telencephalon is the part of the brain responsible for executive functions in fish, according to an experimental study published in PNAS Nexus. Zegni Triki and colleagues used guppies (Poecilia ...

Researchers have provided the first experimental evidence that brain regions can evolve independently of each other during cognitive evolution. This so called mosaic brain evolution was verified ...

The telencephalon is the most anterior structure to arise from the neural tube, and its development — from a simple neuroepithelium to a highly complex structure consisting of cerebral cortex and ...

The telencephalon is the part of the brain responsible for executive functions in fish, according to an experimental study. Zegni Triki and colleagues used guppies (Poecilia reticulata) that had been ...

The relative sizes of specific parts of the guppy brain may explain why some fish are better at learning certain tasks than others. Zegni Triki, a biologist at Stockholm University, had an inkling ...

Different cell types have different functions. They are able to specialize in certain roles because they each express different genes. Understanding what types of cells are in the brain and what they ...

The prevalence of overweight and obesity is largely driven by the widespread availability of high-calorie and highly palatable foods. Even without feeling hungry, some people tend to eat food for the ...
