Bigger brains led to bigger bodies in our ancestors

New research suggests that humans became the large-brained, large-bodied animals we are today because of natural selection to increase brain size. The work contradicts previous models that treat brain size and body size as independent traits. Instead, …

Brain caught ‘filing’ memories during rest

Memories formed in one part of the brain are replayed and transferred to a different area of the brain during rest, according to a new study in rats.The finding suggests that replay of previous experiences during rest is important for memory consolidat…
