Science by the Numbers: Modeling Complex Biological Processes

Monday, December 17, 2018

computer microchip with binary code

Science is a process of trial and error. Most successful research publications are preceded by at least a few false starts and perhaps weeks or even months of tinkering to get experiments to work. For IRP senior investigator Carson Chow, Ph.D., this process of testing and throwing out one potential solution after another is an essential part of his research, so much so that he may go through thousands of iterations before arriving at one that works. However, rather than test each approach himself, he leverages the IRP’s considerable computing power to considerably accelerate the process of sorting the wheat from the chaff.

Neuronal Building Block Underlies Alcohol Addiction

Tuesday, July 31, 2018

3D structure of the NMDA receptor

While many people can easily stop after a beer or two, for others one drink begets many more, ultimately leading to an addiction that drives continuously increasing alcohol consumption over time. New IRP research has identified a specific type of neuronal receptor involved in the development of alcohol dependence in mice, suggesting a possible approach to curbing problematic drinking behaviors in humans addicted to alcohol.

Which Neurons Are Responsible for Anxiety-Related Behaviors?

Tuesday, May 8, 2018

Most people experience anxiety at some point in their lives, whether it’s pre-speech jitters or sweaty palms when their plane takes off. While mild feelings of nervousness are completely normal and can even be beneficial, anxiety can also have negative repercussions if it causes somebody to completely avoid situations like social encounters or taking a flight to visit distant family.

Summertime Brains: Jason Mazique

Tuesday, December 12, 2017

Jason Mazique, who is currently a freshman at Williams College in Williamstown, Massachusetts, spent his 2017 summer working in the lab of NIH IRP Senior Investigator Dr. Harish Pant. During his time at the NIH, Mazique investigated how a particular protein affects neurons in the brain, with implications for neurological conditions like ALS and Alzheimer’s disease

Little Fish in a Big Pond Reveal New Answers to Old Questions

Thursday, April 27, 2017

Reblogged from The NICHD Connection.

Studying the neural control of behavior is a challenge. Researchers must consider an animal’s environment, past experiences, and motivations. Work in relatively simple organisms, for example the invertebrate C. elegans, has teased apart the neural circuitry of highly stereotyped behaviors, like foraging. But in mammals, very little is known, “and that’s surprising given just how important behaviors like this are,” said Dr. Eric Horstick, who studies the molecular mechanisms underlying animal behavior.

Four NIH IRP Researchers Elected to National Academy of Medicine

Monday, October 24, 2016

NIH National Academy of Medicine 2016

This year, members of the National Academy of Medicine elected four NIH Intramural researchers to their ranks, one of the highest honors in science. Learn a bit about each of their research and follow the links to their IRP profiles for more information.

Untangling Alzheimer’s Disease — September is Alzheimer’s Awareness Month

Thursday, September 15, 2016

brain slices - healthy brain compared to severe alzheimers

Inspired by September’s World Alzheimer's Awareness Month and driven by my interest in cognitive aging and dementia, I'm asking my fellow IRP postdoctoral researchers about which approaches they believe hold promise for advancing our understanding of Alzheimer’s disease.

Exercise Releases Brain-Healthy Protein

Thursday, June 30, 2016

Reblogged from the NIH Director's Blog.

Five images of different exercise activities

We all know that exercise is important for a strong and healthy body. Less appreciated is that exercise seems also to be important for a strong and healthy mind, boosting memory and learning, while possibly delaying age-related cognitive decline. How is this so? Researchers have assembled a growing body of evidence that suggests skeletal muscle cells secrete proteins and other factors into the blood during exercise that have a regenerative effect on the brain.

Tracing the Neural Circuitry of Appetite

Wednesday, May 20, 2015

Reblogged from the NIH Director's Blog. Originally posted by Dr. Francis Collins, NIH Director, on May 5, 2015.

If you’ve ever skipped meals for a whole day or gone on a strict, low-calorie diet, you know just how powerful the feeling of hunger can be. Your stomach may growl and rumble, but, ultimately, it’s your brain that signals when to start eating—and when to stop. So, learning more about the brain’s complex role in controlling appetite is crucial to efforts to develop better ways of helping the millions of Americans afflicted with obesity.
