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.
The Usefulness of a Memory Guides Where the Brain Saves It
New research finds that the memories useful for future generalizations are held in the brain separately from those recording unusual events.
Why Insect Memories May Not Survive Metamorphosis
The reshuffling of neurons during fruit fly metamorphosis suggests that larval memories don’t persist in adults.
Memories Help Brains Recognize New Events Worth Remembering
Memories may affect how well the brain will learn about future events by shifting our perceptions of the world.
How the Brain Distinguishes Memories From Perceptions
The neural representations of a perceived image and the memory of it are almost the same. New work shows how and why they are different.
A Good Memory or a Bad One? One Brain Molecule Decides.
When the brain encodes memories as positive or negative, one molecule determines which way they will go.
Why and How Do We Dream?
Dreams are subjective, but there are ways to peer into the minds of people while they are dreaming. Steven Strogatz speaks with sleep researcher Antonio Zadra about how new experimental methods have changed our understanding of dreams.
The Computer Scientist Challenging AI to Learn Better
Christopher Kanan is building algorithms that can continuously learn over time — the way we do.
Scientists Watch a Memory Form in a Living Brain
While watching a fearful memory take shape in the brain of a living fish, neuroscientists see an unexpected level of rewiring occur in the synaptic connections.
