AI Researchers Fight Noise by Turning to Biology
Tiny amounts of artificial noise can fool neural networks, but not humans. Some researchers are looking to neuroscience for a fix.
To Be Energy-Efficient, Brains Predict Their Perceptions
Results from neural networks support the idea that brains are “prediction machines” — and that they work that way to conserve energy.
The Brain Processes Speech in Parallel With Other Sounds
Scientists thought that the brain’s hearing centers might just process speech along with other sounds. But new work suggests that speech gets some special treatment very early on.
Medicine Nobel Prize Goes to Temperature and Touch Discoveries
David Julius and Ardem Patapoutian were awarded the 2021 Nobel Prize in Physiology or Medicine for their discoveries of how we detect heat and touch.
The Brain Doesn’t Think the Way You Think It Does
Familiar categories of mental functions such as perception, memory and attention reflect our experience of ourselves, but they are misleading about how the brain works. More revealing approaches are emerging.
Secret Workings of Smell Receptors Revealed for First Time
Researchers have finally seen how some smell receptors bind to odor molecules. The work yields new insights into one of the most mysterious and versatile senses.
The Brain ‘Rotates’ Memories to Save Them From New Sensations
Some populations of neurons simultaneously process sensations and memories. New work shows how the brain rotates those representations to prevent interference.
Deep Neural Networks Help to Explain Living Brains
Deep neural networks, often criticized as “black boxes,” are helping neuroscientists understand the organization of living brains.
How Your Heart Influences What You Perceive and Fear
The heartbeat and other bodily processes play a surprising role in shaping perception and cognition.
