Gizmodo: Your brain tries to change focus four times per second, study finds

By the time you’re finished reading this sentence, your brain will have rapidly assessed your surroundings 14 times to see if you should focus on something else. At least, that’s what new research suggests. This is a departure from the way we typically think our brains hold attention—neuroscientists have suggested that neurons fire in a […]

USA Today: The decoy effect: Why your brain chooses what you don’t really want

Picture this: You’re at the movie theater concession stand loading up on snacks. You have a choice of a small, medium or large soda. The small is $3.50 and the large is $5.50. It’s a tough decision: The small size may not last you through the whole movie, but $5.50 for some sugar and carbonation […]

Science Daily: How the brain suppresses the act of revenge

Researchers have developed an economic game in which a participant is confronted with the fair behavior of one player and the unfair provocations of another player. They observed which areas were activated as the participant experienced unfairness and anger. Then scientists gave the participant the opportunity to take revenge. They thus identified the location in […]

SciTechDaily: New study shows dehydration alters human brain shape and activity

When dehydration strikes, part of the brain can swell, neural signaling can intensify, and doing monotonous tasks can get harder. With the help of brain scans and a simple, repetitive task to test responsiveness, exercise physiologists at the Georgia Institute of Technology studied volunteer subjects who sweated a lot and did not hydrate. The fluid […]

Science Daily: New information on brain areas linked to tactile sense and metacognitive ability

Sense of touch provides information about textures, objects and physical forces acting on our body. Tactile information is also needed for successful execution of motor tasks such as grasping objects. The aim of Juha Gogulski’s doctoral thesis was to dissect the neural mechanisms underlying different levels of tactile processing in healthy subjects. (August 20, 2018) […]

Wired: Scientists are developing a unique identifier for your brain

Michaela Cordova, a research associate and lab manager at Oregon Health and Science University, begins by “de-metaling”: removing rings, watches, gadgets and other sources of metal, double-checking her pockets for overlooked objects that could, in her words, “fly in.” Then she enters the scanning room, raises and lowers the bed, and waves a head coil […]

Futurity: How our brains predict where speedy objects will go

New research may explain why some people—like sports stars—anticipate and react to fast-moving objects much quicker than others. When Serena Williams returns a lightning-quick tennis serve—most of us marvel at her skill and speed. Considering what the human brain overcomes to make it happen, these kinds of feats are nothing short of miraculous. (August 15, […]

Health Imaging: Yale researchers link genetics, imaging to improve analysis of brain’s molecular activity

Yale University researchers have developed a new approach that can provide more information about molecular function inside the brain through linking gene expression patterns to brain signals captured by MRI-derived T1-weighted/T2-weighted mapping. The study, published online Aug. 6 in Nature Neuroscience, details how the pattern of gene expression across the cerebral cortex flows from sensory […]

Medical Xpress: It’s okay when you’re not okay: Study re-evaluates resilience in adults

Research on how adults deal with adversity has been dominated by studies claiming the most common response is uninterrupted and stable psychological functioning. In other words, this research suggests that most adults are essentially unfazed by major life events such as spousal loss or divorce. These provocative findings have also received widespread attention in the […]

UW News: Men and women show surprising differences in seeing motion

Humans’ ability to notice moving objects has always been a useful skill, from avoiding an animal predator in ancient times to crossing a busy street in the modern world. That evolutionary success attests to the importance of visual motion processing, and why there may be specialized regions of the brain specifically dedicated to this function, […]
