Glowing brain surrounded by faint sketched faces on a warm background

The Default Mode Network: What Your Brain Does When You're Not Doing Anything

The Default Mode Network: What Your Brain Does When You're Not Doing Anything In 2001, a neurologist at Washington University named Marcus Raichle was staring at brain scans and getting frustrated. His data had a problem. Certain brain regions kept lighting up when they weren't supposed

Brain split between a calm blue half and an inflamed red half

Neuroinflammation: When Your Brain's Immune System Attacks

Neuroinflammation: When Your Brain's Immune System Attacks Here's a question that would have seemed crazy twenty years ago: What if depression is an inflammatory disease? The classic explanation for depression is a neurotransmitter imbalance—not enough serotonin, not enough norepinephrine, circuits that aren't firing

Neuralink: Elon Musk's Bet on the Brain

Neuralink: Elon Musk's Bet on the Brain On January 28, 2024, Elon Musk tweeted: "The first human received an implant from Neuralink yesterday and is recovering well." That's it. That's how we found out that the most ambitious brain-computer interface project

Human and robotic hands touching with a spark before a glowing brain

The Line Between Brain and Machine Is Already Blurring

The Line Between Brain and Machine Is Already Blurring In 2012, a woman named Jan Scheuermann fed herself chocolate for the first time in nine years. Jan has spinocerebellar degeneration—a progressive disease that had taken away her ability to move anything below her neck. She couldn't scratch

Translucent blue brain connected to circuit-board traces

Neural Interfaces

Neural Interfaces The Line Between Brain and Machine Is Already Blurring The Core Insight Your brain is an electrical organ. Neurons communicate through voltage spikes—tiny electrical pulses that propagate across networks of billions of cells. Those spikes encode everything: perception, memory, intention, consciousness. We're learning to read

Glowing brain between neural fields with a symbol and downward arrows

Synthesis: What Neuroscience Actually Tells Us About Being Human

Synthesis: What Neuroscience Actually Tells Us About Being Human After seven articles exploring the frontiers of brain science—connectomics, optogenetics, glial cells, neuroinflammation, the default mode network, and predictive processing—it's time to step back and ask the harder question: What does any of this mean for understanding

Glowing brain linked by nerve threads to a robotic prosthetic arm

Motor Prosthetics: Restoring Movement

Motor Prosthetics: Restoring Movement In 2006, Matthew Nagle became the first human to control a computer cursor with an implanted brain electrode array. He had been paralyzed from the neck down after a stabbing four years earlier. Now, with 96 tiny electrodes in his motor cortex, he could move a
