Please join BBI for a seminar and demonstration of Functional Near-Infrared Spectroscopy (fNIRS) by Dr. Afrouz Anderson on Wednesday, January 29, 2020 at 1 p.m. in 0215 Edward St. John Center.
Learning, language acquisition, sensory and motor functions, emotion, social interactions, and the influence of a host of disease processes can all be explored via the fNIRS signal. Dr. Anderson's talk will cover the core concepts of fNIRS, its applications in clinical research, experimental and analytical considerations as well as multimodal imaging.
The revised NIH Grants Policy Statement has been published, replacing the October 2018 version as a standard terms and conditions of awards. This revision applies to all NIH grants and cooperative agreements with budget periods beginning on or after October 1, 2019.
Funding decisions rely heavily on peer review scores, but there is more to the story. NIH Institutes and Centers weigh those scores together with ensuring their entire research portfolio addresses the wide array of diseases, conditions, or other research areas within its mission.
If 2020 has you looking for an opportunity to learn more about working with NIH extramural research, then consider an NIH seminar on program funding and grants administration. These seminars provide the latest policy and process information as well as guidance and resources from NIH and HHS experts.
You might think nutrient-sensing cells in the human GI tract would have no connection whatsoever to autism spectrum disorder (ASD). But these GI cells, called neuropods, could one day help provide a direct link to understanding and treating some aspects of autism and other brain disorders. One researcher recently discovered that cells in the intestine, previously known for their hormone-releasing ability, form extensions similar to neurons, and these extensions connect to nerve fibers in the gut that relay signals to the vagus nerve and onward to the brain.
When you think camouflage, you probably don’t imagine a gleaming turquoise bug that might be mistaken for a fancy brooch. But that’s the surprisingly perfect disguise for the jewel beetle. Scientists previously assumed that iridescent creatures such as dragonflies and some butterflies developed their majestic coloration to attract mates or to warn predators not to eat them because they are poisonous. But a counterintuitive theory first proposed 100 years ago posits that iridescence might instead be a form of camouflage, and a recent study confirms now this theory.
To investigate how the brain processes the distinct basic component of emotional states, researchers asked a group of 15 volunteers to express, define, and rate their emotions while watching the movie Forrest Gump. The volunteers reported scene by scene their feelings and their respective strength on a scale from 1 to 100. Then their answers were compared to those of 15 other persons who had watched the same movie during a fMRI study. The scientists found that the entire set of our emotions is topographically represented in a small region of the brain, a three-centimeter area of the cortex.
Understanding the array of neural signals that occur as an organism makes a decision is a challenge. To tackle it, the authors of a study published last week in Cell imaged large swaths of the larval zebrafish brain as the animals decided which way to move their tails to avoid an undesirable situation. Finding patterns in the data, they were then able to use imaging to predict—10 seconds in advance—the timing and direction of the fish’s movement. The size of the larval zebrafish allowed researchers access to the entire brain of the transparent vertebrae with single-cell resolution.
A team of researchers visited a half dozen multi-day arts and music festivals in the United States and United Kingdom and asked attendees who were not then under the influence of psychedelics about their recent social experiences, mood, and substance use. By surveying them, the researchers were able to characterize the psychological effects of the “afterglow” of psychedelic experiences. The team found that people who had recently used psychedelics such as psilocybin reported a sustained improvement in mood and feeling closer to others after the high had worn off.
Researchers have identified a protein complex that both attracts and repels neurons during brain development. The three proteins Teneurin, Latrophilin, and FLRT hold together and bring neighboring neurons into close contact, enabling the formation of synapses and the exchange of information between the cells. However, in the early phase of brain development, the interaction of the same proteins leads to the repulsion of migrating nerve cells. The detailed insight into the molecular guidance mechanisms of brain cells was possible due to the structural analyses of the protein complex.
Anyone who has desperately searched their kitchen cabinets for a piece of forgotten chocolate knows that the desire for palatable food can be hard to control. But is it really addiction? A study that imaged the brains of minipigs before and after consuming sugar water has drawn comparisons between sugar's effect on the brain and that of addictive drugs. The study was based on experiments done using seven pigs receiving two liters of sugar water daily over a 12-day period. After just 12 days of sugar intake, the researchers saw major changes in the brain's dopamine and opioid systems.
A new study demonstrates that the balance between the neurotransmitters serotonin and dopamine may affect whether or not a person develops social anxiety disorder. Previous studies have focused on either the serotonin or the dopamine system individually, but now researchers argue that an imbalance between serotonin and dopamine transporters in the amygdala and other brain areas important for fear, motivation, and social behavior contribute to the development of social anxiety.
A professor finishes a lecture and checks his computer. A software program shows that most students lost interest about 30 minutes into the lecture—around the time he went on a tangent. The professor makes a note to stop going on tangents. While the technology for this fictional classroom scene doesn’t yet exist, scientists are working toward making it a reality. In a paper published this month, researchers described an artificial intelligence system that analyzes students’ emotions based on video recordings of the students’ facial expressions.
