Can Consciousness Be Explained by Quantum Physics? New Research
One of the most important open questions in science is how our consciousness is established. In the 1990s, long before winning the 2020 Nobel Prize in Physics for his prediction of black holes, physicist...
Treating the Brain Through the Stomach: Tweaking the Gut Microbiome Slowed ALS in Mice
Ask any neuroscientist 20 years ago if gut bug excrement could slow down an untreatable brain disease, and they’d brush off the idea without a second thought.
Yet the gut-brain connection has emerged as one...
A Neuron’s Sense of Timing Encodes Information in the Human Brain
We like to think of brains as computers: A physical system that processes inputs and spits out outputs. But, obviously, what’s between your ears bears little resemblance to your laptop.
Computer scientists know the intimate...

As the rats ran down a short balance beam, stopping occasionally to poke their noses at a water fountain, their brains knew something was off.
Inside the hippocampus, a brain region that documents the stories...
A New Brain Implant Automatically Detects and Kills Pain in Real Time
Chronic pain is like a horror movie monster that sneaks up on you. It’s unpredictable, lingers silently, and when it strikes it’s often too late to tame. More diabolically, our best weapon against it—pain...
Is It Time to Give Up on Consciousness as ‘the Ghost in the Machine’?
As individuals, we feel that we know what consciousness is because we experience it daily. It’s that intimate sense of personal awareness we carry around with us, and the accompanying feeling of ownership and...
