Rotating Brain Waves Help Mind Refocus After Distraction
Neuroscientists have discovered that when the brain is distracted, coordinated “rotating” waves of neural activity help it steer back to focus. Using electrical recordings in animals, the team found that neurons in the prefrontal cortex synchronize in circular patterns—like starlings in flight—to recover from cognitive interruptions.
Human Mind Prefers Simple Explanations Over Complex Truths
New research shows that people tend to prefer simple explanations even when complex ones are more accurate. The study found that individuals focus mainly on visible or known causes while neglecting hidden or absent ones, leading to oversimplified reasoning.
How Chemo Triggers Nerve Damage and How to Stop It
A new study reveals that chemotherapy-induced nerve pain arises from a stress response in immune cells that triggers inflammation and neurotoxicity. Researchers found that activating a cellular stress sensor called IRE1α causes nerve damage and pain during chemotherapy, but blocking it prevents both in mice.
$2 Saliva Test To Help Detect Depression and Schizophrenia
Scientists have developed a portable biosensor that can detect levels of BDNF, a protein linked to mental health conditions such as depression, schizophrenia, and bipolar disorder. The flexible, low-cost device analyzes a drop of saliva in under three minutes, offering a fast, affordable, and noninvasive diagnostic tool.
CBD’s Unseen Effects on the Teenage Brain
Cannabidiol, or CBD, is found in a variety of products, including candies, seltzers, and vapes. It’s pitched to teenagers as a safe way to relieve stress and improve sleep. But animal studies show that CBD can interfere with adolescent brain development, prompting concern about the lack of regulation.
