What Your Brain Is Doing When You’re Not Doing Anything
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.
Why the Human Brain Perceives Small Numbers Better
The discovery that the brain has different systems for representing small and large numbers provokes new questions about memory, attention and mathematics.
What a Contest of Consciousness Theories Really Proved
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.
Is It Real or Imagined? How Your Brain Tells the Difference.
New experiments show that the brain distinguishes between perceived and imagined mental images by checking whether they cross a “reality threshold.”
Self-Taught AI Shows Similarities to How the Brain Works
Self-supervised learning allows a neural network to figure out for itself what matters. The process might be what makes our own brains so successful.
The Computer Scientist Challenging AI to Learn Better
Christopher Kanan is building algorithms that can continuously learn over time — the way we do.
