Recently, researchers at Washington University, St. Louis made a significant breakthrough in developing a blood test for early indications of Alzheimer’s disease. But what exactly is Alzheimer’s disease, how prevalent is it, and why do we seem to be so far away from a treatment or cure? In this post, I provide an overview of […]

Left- vs. Right-Brained: Why the Brain Laterality Myth Persists
Posted by | Perspectives in ResearchYou might have heard artists say they’re right-brained or mathematicians say they’re left-brained. Maybe when you were a kid someone noticed you were left-handed and told you that meant you were creative. The idea that some of us are “left-brained” and others are “right-brained” is extremely popular. But, like so many other appealing ideas, the […]
Why Do Students Pursue a Ph.D. in Neuroscience?
Posted by | A Day in the LifeAs a fourth-year neuroscience Ph.D. student, I appreciate the variety of topics that lie within the umbrella of the nervous system. Nowhere is this more evident than in the diverse backgrounds and passions of my fellow students. To provide a glimpse into the vibrant world of neuroscience research, and to provide insight to others considering […]
Drifting Through the Dark
Posted by | A Day in the LifeI have never wanted to be an astronaut. The idea of hurtling upward in a rocket ship, crashing through the Earth’s atmosphere, and launching into the weightless, densely black sky with the knowledge that you might never return makes me feel a certain loneliness. Yet when friends and family ask what it’s like to do […]
Fuggetaboudit: Is Forgetfulness a Vice or a Virtue?
Posted by | Perspectives in ResearchWhere are my keys? What’s the name of that actor again? Did she say 3 or 4 o’clock? Forgetfulness is a part of life, albeit often an inconvenient one. If you find yourself wishing you would never forget anything, you may want to reconsider. Neuroscientists are beginning to uncover the molecular mechanisms of forgetting. With […]
Discussing the NIH Mandate to Study Sex as a Biological Variable in Basic Biomedical Research
Posted by | Perspectives in ResearchIn one of my courses in the neuroscience Ph.D. program at Johns Hopkins, we recently discussed the 2016 National Institutes of Health (NIH) mandate requiring consideration of sex as a biological variable in grant applications to NIH agencies. Citing the success of the initiative to include both men and women in human clinical trials, the […]
Uncovering a Food Preference Signal in an Overlooked Brain Region
Posted by | Perspectives in ResearchThis October marks the publication of my first lead author scientific article, the culmination of my thesis work thus far. Simply put, I found a previously unknown brain signal in the ventral pallidum that reports how good a food outcome was relative to the other available options. What does this signal mean, and why might […]
A New Animal Model for Bad Decisions
Posted by | Perspectives in ResearchHumans are constantly making decisions about how to spend time, yet we are pretty terrible at doing so effectively. We sit through boring movies, stay in line at a crowded restaurant and continue to pursue low-return projects, because we simply cannot bear to see the time we have already invested in these activities go to […]
Recent Study Reveals How the Brain Learns from Others’ Mistakes
Posted by | Perspectives in ResearchLast month, my friend came back from Mount Kosciuszko with stunning photos and a seriously painful-looking sunburn. As I prepared to undertake the same hike based upon his enthusiastic recommendation, I decided to pack some SPF 50 and planned to reapply every 30 minutes. Without experiencing a sunburn firsthand, I knew to stay sun-safe, thanks […]
That’s Not Fair! — The Neuroscience of Injustice
Posted by | Perspectives in ResearchAs a kid you probably found some decisions by your parents utterly unjust. Perhaps you proclaimed, “That’s not fair!” when you were forced to eat spinach, or if your sibling got something you didn’t. As adults, we still experience intense sensations of injustice, sometimes in response to more serious issues such as human rights, health […]
