Examining the Roots of Opioid Use Disorder

IRP Researchers Are Peering Into the Brain to Learn Why Opioid Drugs Are So Hard to Quit

Monday, March 13, 2023

The ancient Egyptians, despite their significant anatomical knowledge, thought the heart was the seat of intelligence. Over the millennia, that view changed as philosophers and scientists alike came to appreciate the extraordinary role of the brain. It is partly thanks to them that we celebrate Brain Awareness Week every March. In honor of this observance, we took the opportunity to talk with IRP senior investigator Yihong Yang, Ph.D., and postdoctoral fellow Ida Fredriksson, Ph.D., Pharm.D., about their investigation into how cravings for opioids build during a period of prolonged abstinence, often leading to relapse.

Moms’ Caffeine Consumption May Affect Babies’ Brains

Findings Could Explain Why Caffeine Exposure In-Utero Increases Kids’ Risk for Obesity

Between books, the media, and well-meaning friends and relatives, new parents are inundated with advice about how to set their kids up for a happy and healthy future. However, what parents do before their children are even born can also have a huge impact on how they turn out. For instance, new IRP research suggests that a pregnant woman’s caffeine consumption can rewire her baby’s brain in ways that put the child at increased risk for obesity later in life.

Neuroimaging Study Supports Two-Stage Theory of Recall

Results Suggest Dual Functions for Memory-Related Brain Area

Tuesday, August 16, 2022

Scientists studying memory have been closely scrutinizing a brain structure called the hippocampus ever since a man named Henry Molaison — better known as ‘patient H.M.’ — lost his ability to create new memories after surgeons removed that portion of his brain as a last-ditch treatment for his unrelenting epileptic seizures. For the most part, that research has treated the hippocampus as one homogenous structure. However, a recent IRP study lends support to the growing recognition that recall is a multi-stage process in which different parts of the hippocampus play different roles.

Ketogenic Diet May Soothe Alcohol Withdrawal

Human and Animal Studies Point to New Treatment Strategy

Tuesday, June 8, 2021

Interest in the low-carb ‘ketogenetic’ diet has exploded in recent years, with legions of enthusiasts jumping on the bandwagon. The popular dietary regimen has even caught the attention of scientists seeking new treatments for an array of health conditions. For instance, a recent IRP study suggests that a ketogenic diet might make it easier for people with alcohol use disorder to stop drinking.

Mirror Therapy Alters Brain Response in Phantom Limb Patients

Neuroimaging Could Help Tailor Treatment for Amputees

Tuesday, July 23, 2019

Our brains frequently cause us to perceive things that are not real, from high-pitched ringing in an empty room to dancing spots in our vision after staring at a bright light. Even more strangely, people with phantom limb syndrome feel sensations, including pain, in arms and legs that they no longer have. New IRP research into the brain mechanisms underlying phantom limb pain could help hone treatment for individuals living with the condition.

Brain Data Predicts Alcohol Disorder Symptoms

Study Results Could Help Improve Treatment for Alcohol-Related Problems

Tuesday, April 16, 2019

Your brain is always busy, even when you’re not thinking about anything. Scientists believe the way brain cells communicate with one another when the brain is in that ‘resting state’ might differ in individuals with certain diseases. In a recent study of this idea, IRP researchers found that resting state brain activity could effectively predict the severity of alcohol-related problems.

Urban Upbringing Flips Genes’ Effects on Brain Activity

It might seem easy to blame your parents for the way you turned out; after all, they raised you and gave you all of your DNA. But, before throwing blame around, consider saving some for the place where you grew up. According to new IRP research, being raised in an urban environment can dramatically alter how your genes influence your brain.1

Post-Postbac Poster Day Blog Post

Flashback to 2015...

So, it happened, the day the NIH community was waiting for: Postbac Poster Day. The Bethesda campus buzzed with anticipation, and the postbacs did not disappoint. With 580 poster presenters, a lot of research projects and science was shared.
