Like Dumbledore’s wand, a scan can pull long strings of stories straight out of a person’s brain — but only if that person cooperates.
Once the researchers knew which brain activity patterns matched the words in the stories, the team could work backward, using brain patterns to predict new words and ideas. The process inched along in an iterative way. A, then used the brain activity patterns to help pick a winner and ultimately land on the gist of an idea.
A new brain decoding effort gets at the idea of what a person hears, but doesn’t get the exact wording right.A new brain decoding effort gets at the idea of what a person hears, but doesn’t get the exact wording right.Such responses made it clear that the decoders struggle with pronouns, though the researchers don’t know why. “It doesn’t know who is doing what to whom,” Huth said in an April 27 news briefing.
“This study is very impressive, and it gives us a glimpse of what might be possible in the future,” says Sarah Wandelt, a computational neuroscientist at Caltech who wasn’t involved in the study.

Best of Last Week—New mammalian tree of life, an AI to generate food recipes and trialing retinitis pigmentosa therapyIt was a good week for the biological sciences, as a team of neuroscientists at Duke University discovered electrical activity within cells that could change the way scientists think about biological chemistry—they found that imbalanced electrical charges between air and microdroplets of water in nerve cells also exist around other types of cells. Also, an international team of geneticists used the genomes of 241 species to redefine the mammalian tree of life—the work provided a definitive view of the evolutionary timeline of mammals throughout the last 100 million years. And another international team studying a blinking fish found clues that shed light on how our ancestors evolved from water to land—the amphibious mudskipper was found to blink for the same reasons as humans.

Caltech’s Enzyme Discovery Enables New Mechanism for Crossing the Blood–Brain BarrierCaltech researchers discovered an enzyme that enables viral vectors to cross the blood-brain barrier, potentially aiding brain disorder drug development and research. The blood–brain barrier (BBB) is a stringent, nearly impenetrable layer of cells that guards the brain, protecting the vital organ
