Cognition

The brain’s astounding cellular diversity and networked complexity could show how to make AI better.

Complex neural pathways likely arose independently in birds and mammals, suggesting that vertebrates evolved intelligence multiple times.

Zero, which was invented late in history, is special among numbers. New studies are uncovering how the brain creates something out of nothing.

Neuroscience research into people with aphantasia, who don’t experience mental imagery, is revealing how imagination works and demonstrating the sweeping variety in our subjective experiences.

Research suggests that psychedelic drugs can reopen critical periods of brain development to create opportunities for re-learning and psychological healing. In this episode, co-host Janna Levin speaks with Gül Dölen, a neuroscientist studying the therapeutic potential of psychedelic substances.

Our brain waves can align when we work and play closely together. The phenomenon, known as interbrain synchrony, suggests that collaboration is biological.

When your mind is wandering, your brain’s “default mode” network is active. Its discovery 20 years ago inspired a raft of research into networks of brain regions and how they interact with each other.

The discovery that the brain has different systems for representing small and large numbers provokes new questions about memory, attention and mathematics.

A five-year “adversarial collaboration” of consciousness theorists led to a stagy showdown in front of an audience. It crowned no winners — but it can still claim progress.
