Summary: New findings indicate that flies use predictive processing in their visual system to execute rapid evasive maneuvers, suggesting prediction may be a widespread strategy across animal nervous systems for supporting fast behavioral responses. Source: University of Chicago Researchers at the University of Chicago report that flies anticipate changes in their visual environment to carry … Read more

Summary: Unexpected sensory events — such as a sudden sound — make people more likely to stop an ongoing action than when no such cue is present. New research explains how surprising cues speed the brain’s communication with the motor system, improving the ability to halt movements rapidly. Source: University of Iowa. Imagine reaching to … Read more

Summary: Researchers report that couples who frequently hug or hold hands show lower cortisol levels, fewer physical symptoms, and better sleep. Source: Northwestern University. Would it surprise you to learn that simple acts like holding hands while walking, embracing when you return home, or resting your hand on your partner’s shoulder can improve both partners’ … Read more

Summary: A large study of British young adults finds a clear link between loneliness and poorer sleep quality — lonelier participants were more likely to feel tired and have trouble concentrating during the day. Source: King’s College London New research from King’s College London connects loneliness with reduced sleep quality among young adults. Researchers analyzed … Read more

Summary: Researchers are conducting an online study to evaluate whether omega-3 supplements can improve children’s behaviour, mood and mental wellbeing. The trial responds to evidence that most children in the UK consume less than half the recommended amount of omega-3 fats and aims to test whether supplementation can address dietary shortfalls and support cognitive and … Read more

Summary: Advanced neuroimaging shows that people with bipolar depression display reduced left amygdala activity and weaker connectivity with other brain regions compared with those who have unipolar major depression—findings that could improve diagnostic accuracy. Source: Westmead Institute Neuroimaging study identifies amygdala activity and connectivity differences that may help distinguish bipolar disorder from major depression Researchers … Read more

Summary: Researchers have created a “traumatic brain injury (TBI) on a chip” to investigate how concussions might trigger processes linked to Alzheimer’s disease. Using clusters of neurons grown from embryonic mouse cortex, the team exposed these miniature, functioning neural networks to g-forces comparable to those experienced in high-impact sports. The model revealed an immediate spike … Read more

Summary: By learning to accept and channel frustration, people can tap into greater creative potential—using irritation and fatigue as catalysts for fresh ideas and problem-solving approaches. Source: Jacobs University Response inhibition is a cognitive skill that allows people to suppress automatic or habitual reactions in order to act more deliberately. This capacity helps individuals pause, … Read more

Summary: A large multisite study has mapped structural white matter networks in people with bipolar disorder, revealing subtle but widespread differences in how brain regions communicate. Researchers harmonized diffusion MRI data from 449 individuals with bipolar disorder and 510 healthy controls across 16 international sites through the ENIGMA Bipolar Disorder Working Group to identify system-level … Read more

Summary: Researchers identify the genetic cause of intellectual disability in four male patients in record time. Source: Baylor College of Medicine. In a study published today in PLoS ONE, researchers report a rapid discovery linking small deletions on the X chromosome to a previously unrecognized cause of intellectual disability. Using modern genomic databases and rapid … Read more
