What’s my (brain) age again?

What does it mean to age? Is it a purely time-based process, with each passing moment bringing our bodies along an invariant trajectory of decline? Or is it a function of our behavior, dependent on our daily activities and the damage inflicted upon ourselves over time? Clearly, there is a bit of truth in each […]

The Blob

Beware! The Blob   Imagine you are on a trip to Paris. There is so much to see and do, but you decide to go to the local zoo. You are walking around, admiring all the interesting animals. There are beautiful big cats lounging about. There are enormous giraffes feeding on plants. You feast your […]

Open Borders: Remapping the Brain

While reading articles online, you may occasionally stumble across headlines like “Scientists find fear center of the brain,” or “Could this really be where the mind resides?” You might have also heard a TED talk where the speaker discusses how they discovered a part of the brain that makes decisions. Such expressions can take more […]

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 […]

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 […]

Where does Alzheimer’s disease begin?

Sometimes I forget what day of the week it is, where I put my keys, or when a friend’s birthday is- but I never stop to wonder if these brief moments of forgetfulness are normal or a sign of something more serious. For many, occasional short-term memory loss is a normal part of getting older, […]

The Rise and Fall and Rise of Genetic Memory

We are all products of our past, for better or for worse. At first glance, such a statement seems so obvious it hardly bears mentioning; our earlier experiences, both our successes and our failures, shape our current behavior.  But dig just a bit deeper, and it becomes far murkier. What can you call your past? […]

Baby I Swear it’s Déjà Vu

It’s one of the most bizarre sensations in the world: feeling like you’ve entered some sort of time loop and are re-experiencing something that’s already happened before. The rational part of you knows that this is a new experience, and yet, you can’t shake the feeling that you’re somehow reliving a brief moment of your […]

The Neurogenesis Saga: Are new neurons born in the adult human brain?

One of neuroscience’s most heated debates during the past 50 years has been whether or not new neurons are born (a process called neurogenesis) in the adult mammalian brain. Before the late 1990s, we believed that we were born with all the neurons we would have throughout our lives. However, evidence of adult neurogenesis from […]

Remember Tomorrow?

  We humans have an impressive ability to plan for the future — lapsed New Year’s resolutions and overambitious project planners notwithstanding. We can make decisions in the present (like bringing an umbrella) that make our lives easier in the future (we stay dry). Among the animal kingdom, this capacity is distinctly rare. Even animals […]
