People can make better choices when it benefits others
Humans are often motivated by self-interest. Participants in one study, for example, learned a game faster when they earned money for themselves as opposed to another person. However, this pattern changes when physical harm enters the equation. As social beings, we need to learn to avoid actions that hurt others and it turns out that […]

How the brain’s internal states affect decision-making
Matthew Smith and Byron Yu, along with former Ph.D. student Ben Cowley (Ph.D., SCS ’18), have studied the neural basis through which internal states in the brain affect decision-making over an extended period of time. Through recording the activity of populations of neurons simultaneously in two brain areas, they were able to gain unprecedented insight […]

Autism-Cholesterol Link
Researchers at Harvard Medical School, Massachusetts Institute of Technology and Northwestern University have identified a subtype of autism arising from a cluster of genes that regulate cholesterol metabolism and brain development. The researchers say their findings, published Aug. 10 in Nature Medicine, can inform both the design of precision-targeted therapies for this specific form of […]

Sleepiness can have a negative impact on your social life
Sleepiness affects cognitive performance, motivation and behaviour. More and more people are suffering from sleep disorders, but the effects of sleepiness on social activity, which plays an important role in one’s overall health and well-being, have remained relatively unknown. In order to increase our understanding in this area, researchers at Stockholm University and Karolinska Institutet […]

Targeting a Chronic Pain Gateway Could Bring Relief
Something like a quarter of the world’s population suffers from chronic pain at some point in their lives. As opposed to acute pain – for example, the feeling after hitting your finger with a hammer – chronic pain may not even have a clear cause, and it can linger for years or lifetimes. The burden […]

Is Risk of Alzheimer’s Linked to Specific Sleep Patterns?
Disturbed sleep patterns do not cause Alzheimer’s disease but people who are at high genetic risk of developing Alzheimer’s disease may be more likely to be a “morning person,” have shorter sleep duration and other measures of sleep disturbance and are less likely to have insomnia, according to a study published in the August 19, […]

Study finds that sleep restriction amplifies anger
Feeling angry these days? New research suggests that a good night of sleep may be just what you need. This program of research comprised an analysis of diaries and lab experiments. The researchers analyzed daily diary entries from 202 college students, who tracked their sleep, daily stressors, and anger over one month. Preliminary results show […]

Hope for 500 000 insomniacs in Norway
Approximately 500 000 Norwegians suffer from chronic sleep disorders, also called insomnia. Researchers have long known that cognitive behavioural therapy for insomnia is the best documented treatment, but few people have access to such therapy. A fully automated digital version of this treatment has proven effective for many patients and can reduce the use of […]

Circadian Rhythms Help Guide Waste from Brain
New research details how the complex set of molecular and fluid dynamics that comprise the glymphatic system – the brain’s unique process of waste removal – are synchronized with the master internal clock that regulates the sleep-wake cycle. These findings suggest that people who rely on sleeping during daytime hours are at greater risk for […]
