Picture this: a patient walks into my clinic complaining about constipation that's been getting worse for fifteen years. No big deal, right? Happens to a lot of people. Then, a decade later, that same patient comes back - this time with a tremor in their right hand. Two very different complaints,...
Think of your brain as a sprawling metropolis. The prefrontal cortex is downtown - the business district where rational decisions get made and executive orders flow to the rest of the city. The amygdala? That's the 24-hour alarm center, always monitoring for threats. Between them run information...
Here's something that'll flip your bedtime lecture on its head: some teenagers who sleep less than eight hours a night are doing just fine. Their brains are basically shrugging and saying, "We got this." Meanwhile, other short-sleeping teens are quietly collecting neurological IOUs that come due...
In five years, this discovery might mean your doctor runs a quick genetic test before prescribing medication for alcohol use disorder, and instead of the current coin-flip odds of treatment success, you get a therapy tailored to your brain's specific wiring. That future got a lot closer thanks to a...

You know that feeling when someone you love gently strokes your arm and your entire nervous system seems to exhale? Turns out your body has an entire class of nerve fibres dedicated to precisely that moment - and science is only now working out how the whole operation runs.

Your body runs on a schedule more precise than any Swiss railway, and at the heart of this temporal machinery sits cortisol - the hormone that gets you out of bed in the morning and (mostly) lets you sleep at night. Cortisol surges at dawn, tapers through the afternoon, and hits its lowest point...
Your ears need estrogen. Yeah, that hormone. The one typically associated with puberty, bone health, and about a thousand other biological processes. Turns out the cochlea - that snail-shaped hearing apparatus in your inner ear - has estrogen receptors just sitting there, waiting for their...
