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.
How Animals Map 3D Spaces Surprises Brain Researchers
When animals move through 3D spaces, the neat system of grid cell activity they use for navigating on flat surfaces gets more disorderly. That has implications for some ideas about memory and other processes.
Animals Count and Use Zero. How Far Does Their Number Sense Go?
Crows recently demonstrated an understanding of the concept of zero. It’s only the latest evidence of animals’ talents for numerical abstraction — which may still differ from our own grasp of numbers.
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.
Artificial Neural Nets Finally Yield Clues to How Brains Learn
The learning algorithm that enables the runaway success of deep neural networks doesn’t work in biological brains, but researchers are finding alternatives that could.
Reasons Revealed for the Brain’s Elastic Sense of Time
New research finds that the subjective experience of time is linked to learning, thwarted expectations and neural fatigue.
