Ants store long- and short-term memories on different sides of their brains

Researchers were not right about left brains

"The theory of “universal grammar” proposes that children are born with an instinctive knowledge of the language rules common to all humans. Upon exposure to a specific language, such as English or Arabic, children simply fill in the details around those rules, making the process of learning a language fast and effective.

The other theory, known as the “critical period hypothesis”, posits that at around the age of puberty most of us lose access to the mechanism that made us such effective language learners as children. These theories have been contested, but nevertheless they continue to be influential.

Despite what these theories would suggest, however, research into language learning outcomes demonstrates that younger may not always be better.

Why Animals Evolved to Favor One Side of the Brain

Most left-handers can rattle off a list of their eminent comrades-in-arms: Oprah Winfrey, Albert Einstein, and Barack Obama, just to name three, but they may want to add on cockatoos, "southpaw" squirrels, and some house cats. "Handed-ness" or left-right asymmetry is prevalent throughout the animal kingdom, including in pigeons and zebrafish. But why do people and animals naturally favor one side over the other, and what does it teach us about the brain's inner workings?
