How the Brain Creates a Timeline of the Past

The brain can’t directly encode the passage of time, but recent work hints at a workaround for putting timestamps on memories of events.

The Brain Maps Out Ideas and Memories Like Spaces

Emerging evidence suggests that the brain encodes abstract knowledge in the same way that it represents positions in space, which hints at a more universal theory of cognition.

A Math Theory for Why People Hallucinate

Psychedelic drugs can trigger characteristic hallucinations, which have long been thought to hold clues about the brain’s circuitry. After nearly a century of study, a possible explanation is crystallizing.

To Remember, the Brain Must Actively Forget

Researchers find evidence that neural systems actively remove memories, suggesting that forgetting may be the default mode of the brain.

To Make Sense of the Present, Brains May Predict the Future

A controversial theory suggests that perception, motor control, memory and other brain functions all depend on comparisons between ongoing actual experiences and the brain’s modeled expectations.
