From symptoms to biology: shifting definitions of Alzheimer’s disease

As a neuroscientist studying Alzheimer’s, I’m reminded of its far-reaching impact each time a barista, cashier, or Lyft driver makes small talk by asking what I do for a living. Unfortunately, this devastating disease needs no introduction. Considering its ubiquity, it’s surprising that a debate broke out recently among leaders in the field over the […]

Conscious in Dreamland: The Neuroscience of Lucid Dreaming

Left Brain, Right Brain, Red Brain, Blue Brain

[En español] With the first presidential debate of 2016 quickly approaching, it’s a good time to consider whether your brain has already cast its vote. There is no shortage of articles that imply your political leanings are reflected in your brain’s structure and function (e.g. Is your brain liberal or conservative?—Fox News, Experts say liberal […]

Forget About It

[En español] In the midst of studying for finals, forgetting is the enemy. You can easily remember the lyrics to your favorite 90s hit, but the names of the 12 cranial nerves elude you. We often think about forgetting as something pathological. We become frustrated by that all too familiar tip-of-your-tongue feeling and in extreme […]

What can your tongue see?

Picture this: you’re riding your bike on a cool fall afternoon. You’re blind but have no difficulty navigating through the streets without the aid of your eyes. Rather, the world comes into view through waves of sound bouncing off nearby objects in response to the bursts of clicking noises you create with your tongue. Since […]
