Memory

New research finds that the memories useful for future generalizations are held in the brain separately from those recording unusual events.

The reshuffling of neurons during fruit fly metamorphosis suggests that larval memories don’t persist in adults.

Memories may affect how well the brain will learn about future events by shifting our perceptions of the world.

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.

When the brain encodes memories as positive or negative, one molecule determines which way they will go.

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.

Christopher Kanan is building algorithms that can continuously learn over time — the way we do.

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.

Researchers have mapped hundreds of semantic categories to the tiny bits of the cortex that represent them in our thoughts and perceptions. What they discovered might change our view of memory.
