To Pay Attention, the Brain Uses Filters, Not a Spotlight
A brain circuit that suppresses distracting sensory information holds important clues about attention and other cognitive processes.
A Mathematical Model Unlocks the Secrets of Vision
Mathematicians and neuroscientists have created the first anatomically accurate model that explains how vision is possible.
In Brain’s Electrical Ripples, Markers for Memories Appear
Researchers found that elongating certain brain signals in rats improved their memory. The work revealed a new property to look out for in the hunt for “biomarkers” of learning.
Where We See Shapes, AI Sees Textures
To researchers’ surprise, deep learning vision algorithms often fail at classifying images because they mostly take cues from textures, not shapes.
Do Brains Operate at a Tipping Point? New Clues and Complications
New experimental results simultaneously advance and challenge the theory that the brain’s network of neurons balances on the knife-edge between two phases.
Brains Speed Up Perception by Guessing What’s Next
Your expectations shape and quicken your perceptions. A new model that explains how that happens also suggests it’s time to update theories about sensory perception and decision making.
Goals and Rewards Redraw the Brain’s Map of the World
Two new studies show that the brain’s navigation system changes how it represents physical space to reflect personal experience.
How the Brain Links Gestures, Perception and Meaning
Neuroscience has found that gestures are not merely important as tools of expression but as guides of cognition and perception.
Neuroscience Readies for a Showdown Over Consciousness Ideas
To make headway on the mystery of consciousness, some researchers are trying a rigorous new way to test competing theories.
