Astrocytes, the Underrated Stars

[En español] You usually hear the term “brain cell” referring to neurons, like they’re the only cell type present in the brain.

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 […]

Did you see that? The Mysteries of Sensory Deprivation

When I was a kid swimming in the neighbor’s pool, I loved to float on my back, eyes closed, with ears submerged so that I could only hear the muted sounds of the water around me.

Defining Cognitive Adulthood: When Neuroscience Influences Law

In 2006, a grand jury convicted Evan Miller in a homicide case, sentencing him to mandatory life imprisonment without the possibility for parole. At the time of his crime, Evan was 14-years-old. Years later, after a series of appeals, Evan’s case–Miller vs. Alabama–made it to the Supreme Court, which ruled that a sentence of life […]

The Neuroscience of Laughter

Think back to the last time you had a real, hearty laugh: mouth in a wide smile, eyes crinkled and tearing, breath leaving your body in short bursts if you could get any breath out at all. For humans, there are few more pleasurable experiences or greater expressions of joy as laughter. We use laughter […]

Snake Eyes: The Fear That Built Your Brain

Indiana Jones is a quintessential American hero, his fedora, satchel, and whip instantly recognizable around the world. He lives a double life, a scholarly professor of anthropology in public and a globetrotting treasure hunter in private. He defeats the Nazis and always gets the girl, displaying daring and fearlessness, with one notable exception. He has […]

A Neuroscience Perspective on the Lifelong Consequences of Detaining Kids at the Border

[En español] If you’ve been even partially tuned in to the news over the last few months, you’ve heard about the gut-wrenching separation of children from their parents at the United States border and the detainment centers where these children have been held. You may have seen pictures of young kids in cages, been watching when […]

Upload Complete: Transferring your brain to a digital format

Imagine a future in which your brain–conscious mind, memories, and emotions included–could be uploaded to a computer. Once running, the complex computer code would be able to perfectly reflect your mind: reacting as you would, showing your major personality traits, holding your unique knowledge from your life as a human. Maybe your personal code could […]
