Neural sleep patterns emerged at least 450 million years ago

Researchers at the Stanford University School of Medicine have found that neural signatures in sleeping zebrafish are analogous to those of humans, suggesting that the brain activity evolved at least 450 million years ago, before any creatures crawled out of the ocean. Scientists have known for more than 100 years that fish enter a sleeplike state, but until now they […]

Proofs of parallel evolution between cognition, tool development, and social complexity: A study analyses the selective attention processes that determine how we explore and interact with our environment

Researchers examined the visual response of 113 individuals when observing prehistoric ceramics belonging to different styles and societies. The ceramics analysed cover 4,000 years (from 4000 B.C. to the change of era) of Galician prehistory (north-west Iberia), and are representative of ceramic styles, such as bell-beaker pottery, found throughout Europe. The results indicate that the visual behaviour follows the same […]
