A ‘Self-Aware’ Fish Raises Doubts About a Cognitive Test

A report that a fish can pass the “mirror test” for self-awareness reignites debates about how to define and measure that elusive quality.

New AI Strategy Mimics How Brains Learn to Smell

Machine learning techniques are commonly based on how the visual system processes information. To beat their limitations, scientists are drawing inspiration from the sense of smell.

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.

Her Key to Modeling Brains: Ignore the Right Details

Being able to think like a physicist helps Carina Curto, a mathematician-turned-neuroscientist, pull insights about the human brain out of theoretical models.

Brains May Teeter Near Their Tipping Point

In a renewed attempt at a grand unified theory of brain function, physicists now argue that brains optimize performance by staying near — though not exactly at — the critical point between two phases.
