Few things can delight an adult more easily than the uninhibited, effervescent laughter of a baby. Yet baby laughter, a new study shows, differs from adult laughter in a key way: Babies laugh as they both exhale and inhale, in a manner that is remarkably similar to nonhuman primates. The research will be described by

In order to learn about the world, an animal needs to do more than just pay attention to its surroundings. It also needs to learn which sights, sounds and sensations in its environment are the most important and monitor how the importance of those details change over time. Yet how humans and other animals track

Artificial intelligence can help us to better understand the causes of religious violence and to potentially control it, according to a new Oxford University collaboration. The study is one of the first to be published that uses psychologically realistic AI — as opposed to machine learning. The study published in The Journal for Artificial Societies

Neurons in the human brain receive electrical signals from thousands of other cells, and long neural extensions called dendrites play a critical role in incorporating all of that information so the cells can respond appropriately. Using hard-to-obtain samples of human brain tissue, MIT neuroscientists have now discovered that human dendrites have different electrical properties from

A team of scientists has uncovered the neural processes mice use to ignore their own footsteps, a discovery that offers new insights into how we learn to speak and play music. The research is reported in the journal Nature. “The ability to ignore one’s own footsteps requires the brain to store and recall memories and

We make snap judgments of others based not only on their facial appearance, but also on our pre-existing beliefs about how others’ personalities work, finds a new study by a team of psychology researchers. Its work, reported in the journal Proceedings of the National Academy of Sciences, underscores how we interpret others’ facial features to

A team of researchers at the University of Minnesota have, for the first time, fully 3D printed an array of light receptors on a hemispherical surface. This discovery marks a significant step toward creating a “bionic eye” that could someday help blind people see or sighted people see better. The research is published today in

One of the most intriguing questions about the human brain is also one of the most difficult for neuroscientists to answer: What sets our brains apart from those of other animals? “We really don’t understand what makes the human brain special,” said Ed Lein, Ph.D., Investigator at the Allen Institute for Brain Science. “Studying the

You don’t focus as well as you think you do. That’s the fundamental finding of a team of researchers from Princeton University and the University of California-Berkeley who studied monkeys and humans and discovered that attention pulses in and out four times per second. “Our subjective experience of the visual world is an illusion,” said

The desire for revenge can be the consequence of a feeling of anger. But is this the case at the cerebral level? What happens in the human brain when injustice is felt? To answer these questions, researchers from the University of Geneva (UNIGE), Switzerland, have developed an economic game in which a participant is confronted
