Tablets and other mobile computing devices are part of everyday life, but using them can be difficult for people with paralysis. New research from the BrainGate* consortium shows that a brain-computer interface (BCI) can enable people with paralysis to directly operate an off-the-shelf tablet device just by thinking about making cursor movements and clicks. In

Why do we like the bitter taste of coffee? Bitterness evolved as a natural warning system to protect the body from harmful substances. By evolutionary logic, we should want to spit it out. But, it turns out, the more sensitive people are to the bitter taste of caffeine, the more coffee they drink, reports a

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
