Your Hippocampus Runs a Dual-Purpose Clock-and-Memory System

Your Hippocampus Runs a Dual-Purpose Clock-and-Memory System

Your brain loves a good efficiency hack. Why build two separate systems when one will do? This seems to be evolution's philosophy when it comes to how your hippocampus handles memory and timing. According to a study in Cell Reports, the same neurons that help you remember what happened are...

Your Hearing Brain Actually Sees Things (And No, It's Not a Mistake)

Your Hearing Brain Actually Sees Things (And No, It's Not a Mistake)

Scientists have been arguing about whether primary sensory cortices only handle their "assigned" sense or whether they moonlight with other senses too. A recent study threw a wrench in things by suggesting that visual signals showing up in unexpected brain regions were actually just face movement...

Your Gut Bacteria Apparently Want You to Skip Meals, and Your Brain Might Thank Them

Your Gut Bacteria Apparently Want You to Skip Meals, and Your Brain Might Thank Them

Here's a plot twist for your Tuesday: the path to clearer thinking might run through your intestines, and specifically through the trillions of bacteria living there. A study in Gut found that alternate-day fasting improves cognitive function in people with obesity, and the effect seems to work...

Your Gut Has Hundreds of Millions of Neurons and Nobody Can Agree How to Count Them

Your Gut Has Hundreds of Millions of Neurons and Nobody Can Agree How to Count Them

Picture this: you're at a party and three different guests describe the same person as "tall with brown hair," "medium height with auburn hair," and "lanky with reddish hair." Are they describing the same human? Different people? Impossible to say.

Your Dormant Memories Are Guarded by Specific Neurons (And Scientists Can Now Unlock Them)

Your Dormant Memories Are Guarded by Specific Neurons (And Scientists Can Now Unlock Them)

You know that frustrating experience where you're absolutely certain you know something, but you just can't access it? The name of that actor, the word for that thing, that fact you definitely learned in school? The memory is in there somewhere. You can feel it. But the door to it is locked.

Your Cells Have a Secret Handshake Between the Warehouse and the Front Door

Your Cells Have a Secret Handshake Between the Warehouse and the Front Door

Picture this: deep inside your neurons, there's basically a very needy storage warehouse constantly texting the front door. "Hey, we're running low on calcium over here!" And the front door, being a good sport, opens up to let more in. This molecular buddy system turns out to be way more...

Your Brain's Surface Is Like a Fingerprint, and AI Just Learned to Match Them

Your Brain's Surface Is Like a Fingerprint, and AI Just Learned to Match Them

Here's the thing about brains: they're all shaped differently. Like snowflakes, but wrinklier and way more opinionated about where they put their folds. This presents a real headache for neuroscientists who want to compare brain scans across different people. It's like trying to overlay a map of...

Your Busy Schedule Might Be a Dementia Risk Factor

Your Busy Schedule Might Be a Dementia Risk Factor

We know exercise reduces dementia risk. So does good sleep, social engagement, and healthy eating. But there's a catch: all of these take time. And time, according to a provocative commentary in The Lancet Healthy Longevity, is itself a social determinant of brain health that we've largely ignored.

Your Brain's Sugar Coating Is Tiny, Mysterious, and Probably More Important Than You Think

Your Brain's Sugar Coating Is Tiny, Mysterious, and Probably More Important Than You Think

If you were to catalog everything in your brain by weight, glycans would barely register. These complex sugar molecules, attached to proteins and lipids, make up less than 1% of brain mass. They're the molecular equivalent of that drawer in your kitchen that you never think about until you need...

Your Brain's Sensory Bouncer Is Stuck Letting Everyone In, And That's a Problem

Your Brain's Sensory Bouncer Is Stuck Letting Everyone In, And That's a Problem

You know that feeling when you're trying to work and there's construction noise outside, your coworker is humming, the fluorescent lights are buzzing, and somehow you can hear someone three cubicles over eating chips? Now imagine feeling that overwhelmed all the time. For many people with fragile X...
