Researchers attached electrodes to neurons in monkeys, showed them pictures of faces, and then reconstructed the faces reading brain waves.
After decades of work, scientists at Caltech may have finally cracked our brain’s facial recognition code. Using brain scans and direct neuron recording from macaque monkeys, the team found specialized “face patches” that respond to specific combinations of facial features.
Like dials on a music mixer, each patch is fine-tuned to a particular set of visual information, which then channel together in different combinations to form a holistic representation of every distinctive face.
There are so many ways this could be used irresponsibly, but to be honest, tech-enhanced photographic memory sounds kind of awesome.

Using functional magnetic resonance imaging, researchers monitored brain activity in seven people while the subjects listened to two hours of stories from the Moth Radio Hour. The researchers then used that data to map words to parts of the brain. An interactive viewer by Alexander Huth lets you see what words lit up parts of the brain for one of the subjects.
Colors represent semantic categories such as numeric, social, and violent. Just click on a part of the brain to see which words most associated with an area (or a voxel they’re called). Pan, zoom, and rotate for various angles. [via @wattenberg]

This week, Science for the People is trying to better understand our human brain, it’s quirky ways and unexpected processes, so we can use it better in daily life. We’ll speak with Guy Harrison, author of Good Thinking: What You Need to Know to be Smarter, Safer, Wealthier, and Wiser, about how to cope with our brain’s built-in pitfalls. And we’ll speak to Ben Lillie about The Story Collider, a podcast that blends science and storytelling to show how science touches everyone, scientist and layperson alike.
Don’t forget to support the Science for the People on Patreon to keep the sciencey goodness flowing toward your ear holes.
