The Stars in Our Brains: The Role of Astrocytes in Alcohol Use
By Mariam Melkumyan What are those star-shaped cells doing in our brains? Astrocytes are rightly named for their stellate shape, and in my opinion, they are the star of the show when it comes to the functioning of the brain. Astrocytes are important for the blood-brain barrier, for giving support to neurons by supplying the … Continue reading The Stars in Our Brains: The Role of Astrocytes in Alcohol Use
Brainstorming a Way to Conquer Death
Credit: Skeeze from Pixabay Scientists’ jobs depend upon answering thought-provoking questions, but as a consequence of working in niche research areas, the answers they discover often lack lasting impact on the wider scientific community. However, once in a while, a study will exceed the standard and provoke profound and universal ethical questions. Vrselja et al.’s … Continue reading Brainstorming a Way to Conquer Death
What is Déjà Vu?
By: Jordan Gaines Lewis, 5th year student in the Neuroscience Graduate Program What is déjà vu? Many of us know the feeling. You'll be going about your day, minding your own business, folding some laundry...nothing out of the ordinary. Suddenly a sensation of familiarity washes over you, and you're completely aware that it's happening. I've been here … Continue reading What is Déjà Vu?
Humans are Wired for Prejudice, but That Doesn’t Have to be the End of the Story
By: Caitlin Millett, 3rd year PhD candidate in the Neuroscience Graduate Program Humans are highly social creatures. Our brains have evolved to allow us to survive and thrive in complex social environments. Accordingly, the behaviors and emotions that help us navigate our social sphere are entrenched in networks of neurons within our brains. Social motivations, such as … Continue reading Humans are Wired for Prejudice, but That Doesn’t Have to be the End of the Story
How Fancy Labels Fool Us: The Neuroscience Behind Bias

With each passing season, finding the perfect gift for loved ones seems to become more and more difficult—a phenomenon not unrelated to the seemingly exponential growth in buying options each year. So … Continue reading How Fancy Labels Fool Us: The Neuroscience Behind Bias
Smells Ring Bells: How Smells Can Trigger Emotions and Memories
By: Amanda White, Research Technologist in the Department of Psychiatry Autumn has arrived, bringing with it some of my favorite scents: bonfire smoke, pumpkin spice (DON’T JUDGE!), and, most of all, crisp autumn air. Stepping outside on an October morning and breathing instantly transports me back in time. I’m at Penn State. It’s a cool, … Continue reading Smells Ring Bells: How Smells Can Trigger Emotions and Memories
NFL Players Sue over Painkillers—Because They’re Addicted
By: Andrew Huhn, 4th year PhD candidate in the Neuroscience Graduate Program America loves football. Brutal, high-flying, smash-mouth football. The players seem like gladiators from another era. Chiseled out of stone, they feel no pain as they run, jump, and catch with a grace that appears super-human. The reality is, however, that they do feel pain—and often … Continue reading NFL Players Sue over Painkillers—Because They’re Addicted
A Prosthesis to Fix Broken Memories
By: Daniel Hass, 2nd year PhD candidate in the Neuroscience Graduate Program The Defense Advanced Research Projects Agency (DARPA) has been a major funding source for the development of unique and innovative technologies under its motto of “driving technological surprise.” Some of DARPA’s current projects include designing bullets that can adjust their course in-flight, novel techniques to … Continue reading A Prosthesis to Fix Broken Memories
What’s it like to get an MRI?
By: Jordan Gaines Lewis, 3rd year PhD candidate in the Neuroscience Program During my first year at Penn State College of Medicine, I participated in an MRI research study. I laid in an MRI machine for 45 minutes and looked at pictures of chocolate while smelling chocolate odors. Tough life, right? (Hershey really is the sweetest place … Continue reading What’s it like to get an MRI?
