Why the Human Brain Perceives Small Numbers Better
The discovery that the brain has different systems for representing small and large numbers provokes new questions about memory, attention and mathematics.
Bats Use the Same Brain Cells to Map Physical and Social Worlds
New research in social bats raises the intriguing possibility that evolution can reprogram the brain’s “place cells,” which are typically associated with location, to encode all kinds of environmental information.
These Cells Spark Electricity in the Brain. They’re Not Neurons.
For decades, researchers have debated whether brain cells called astrocytes can signal like neurons. Researchers recently published the best evidence yet that some astrocytes are part of the electrical conversation.
The Hidden Brain Connections Between Our Hands and Tongues
Sticking out your tongue while doing delicate work with your hands reveals a history of evolutionary relationships.
How the Brain Protects Itself From Blood-Borne Threats
To buffer the brain against menaces in the blood, a dynamic, multi-tiered system of protection is built into the brain’s blood vessels.
How a Human Smell Receptor Works Is Finally Revealed
After decades of frustration, researchers have determined how an airborne scent molecule links to a human smell receptor.
Researchers Discover a More Flexible Approach to Machine Learning
“Liquid” neural nets, based on a worm’s nervous system, can transform their underlying algorithms on the fly, giving them unprecedented speed and adaptability.
