Perceptions of Musical Octaves Are Learned, Not Wired in the Brain
Singing experiments with residents of the Bolivian rainforest demonstrate how biology and experience shape the way we hear music.
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 Power Law Keeps the Brain’s Perceptions Balanced
Researchers have discovered a surprising mathematical relationship in the brain’s representations of sensory information, with possible applications to AI research.
Your Brain Chooses What to Let You See
Beneath our awareness, the brain lets certain kinds of stimuli automatically capture our attention by lowering the priority of the rest.
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.
