Transcranial direct current stimulation (tDCS) sounds scary, but it's actually pretty gentle. You run a tiny electrical current through the brain via electrodes stuck to the scalp. We're talking 1-2 milliamps, not the dramatic electroshock therapy you've seen in movies. And it can actually help...
The amygdala is crucial for fear learning - but it's not one thing. GABAergic interneurons (the inhibitory cells) come in multiple flavors, and a study in Cell Reports systematically compares their wiring and activity during fear and extinction learning.
The idea of boosting your memory with non-invasive brain stimulation sounds like something from a late-night infomercial. "Zap your brain, remember everything!" Except scientists have actually been trying to make this work for years, with results that have been, let's say, underwhelming. Modest...
The blood-brain barrier is your brain's bouncer, a highly selective gatekeeper that keeps toxins, pathogens, and general blood weirdness out while letting nutrients through. It's the reason your brain doesn't get infected every time you have a cold, and it's why most drugs can't reach your brain...
Ever filled out one of those psychological questionnaires that tells you you're an "emotional eater" or a "restrained eater" or whatever fancy label captures your complicated relationship with food? Congratulations, you've participated in one of psychology's messiest measurement problems. A review...
In your healthy brain, tau protein is a team player. It helps stabilize the little highways inside neurons that transport cargo around. But in Alzheimer's disease and other tauopathies, tau goes rogue. Specifically, it gets snipped at a particular spot, position 421, and this broken version starts...
Urban data is a nightmare. Cities are constantly changing: new highways redirect traffic, subway extensions shift ridership patterns, policy changes alter behavior overnight. AI models trained on yesterday's city keep getting blindsided by today's reality. By the time they've learned the new...
Deep in your brain, there's a structure called the pulvinar that neuroscientists have been side-eyeing for years. It's the largest nucleus in the thalamus, it connects to basically everywhere in the cortex, and for a long time, nobody could quite figure out how to make sense of it. It's like that...
Small cell lung cancer was already one of the scariest diagnoses you could get. Aggressive, fast-spreading, and fatal for over 200,000 people annually, with more than half of cases already metastasized by the time they're caught. The brain is one of its favorite places to set up shop.
If you've ever taken a neuroscience course, you've probably heard of the Morris water maze. It's the classic memory test: put a mouse in a pool, hide a platform under the water, and see if the little guy can remember where the escape route is. If the mouse finds the platform faster over repeated...
