Dueling Brain Waves Anchor or Erase Learning During Sleep
While we sleep, one kind of slow brain wave helps to reinforce memories, but a competing wave weakens them.
A Mathematical Model Unlocks the Secrets of Vision
Mathematicians and neuroscientists have created the first anatomically accurate model that explains how vision is possible.
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.
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.
You Are Getting Sleepy — Tagged Proteins May Point to Why
The identification of SNIPPs, a set of proteins found primarily at the brain’s synapses, brings science closer to understanding why we need to sleep.
‘Functional Fingerprint’ May Identify Brains Over a Lifetime
A unique neurological “functional fingerprint” allows scientists to explore the influence of genetics, environment and aging on brain connectivity.
