High-Fat Diet Alters Brain’s Response to Food

Mouse Study Identifies Neurological Obstacle to Dietary Improvements

Tuesday, September 15, 2020

Every morning, thousands of Americans wake up intending to eat more healthfully, only to find themselves chowing down on a greasy burger at dinnertime. In addition to the many biological and socioeconomic obstacles to healthy eating, a salad can just plain seem unappealing compared to a plate of crispy fries. According to new IRP research, a high-fat diet can dramatically alter how the brain responds to food in ways that make a more wholesome meal less enticing and satisfying.

Let There Be Light!

Sunday, November 16, 2014

Optogenetics, a new technology used to control brain activity with light, has revolutionized the field of neuroscience in the past decade. The combination of two powerful tools, genetics and optics, has provided both temporal and spatial acuity in understanding how the brain works in response to sensory and motor cues in the environment. At the recent NIH Research Festival symposium titled “Optogenetic approaches to investigating the nervous system,” fellows and scientists from the NIH community presented their research encompassing topics that make use of this approach to study different systems.
