Functional neuroimaging
Functional neuroimaging is the use of neuroimaging technology to measure an aspect of brain function, often with a view to understanding the relationship between activity in certain brain areas and specific mental functions. It is primarily used as a research tool in cognitive neuroscience and neuropsychology. Common methods include positron emission tomography (PET), functional magnetic resonance imaging (fMRI), multichannel electroencephalography (EEG) or magnetoencephalography (MEG), and near infrared spectroscopic imaging (NIRSI). PET, fMRI and NIRSI can measure localized changes in cerebral blood flow related to neural activity.

Jan. 18, 2026 Researchers have identified OTULIN, an immune-regulating enzyme, as a key trigger of tau buildup in the brain. When OTULIN was disabled, tau vanished from neurons and brain cells remained healthy. The findings challenge long-held assumptions about ...
Jan. 18, 2026 While social media continues to circulate claims linking acetaminophen to autism in children, medical experts say those fears distract from a far more serious and proven danger: overdose. Acetaminophen, found in Tylenol and many cold and flu ...
Jan. 18, 2026 When scientists sent bacteria-infecting viruses to the International Space Station, the microbes did not behave the same way they do on Earth. In microgravity, infections still occurred, but both viruses and bacteria evolved differently over time. ...
Jan. 18, 2026 A long-running Swedish study has followed adults for nearly five decades, uncovering when physical decline truly begins. Fitness and strength start slipping around age 35, then worsen gradually with age. The encouraging twist: adults who began ...

Jan. 16, 2026 Bamboo shoots may be far more than a crunchy side dish. A comprehensive review found they can help control blood sugar, support heart and gut health, and reduce inflammation and oxidative stress. Laboratory and human studies also suggest bamboo may ...
Jan. 16, 2026 Moderate video gaming appears harmless, but heavy gaming may take a toll on young people’s health. Researchers found that students gaming more than 10 hours a week had worse diets, higher body weight, and poorer sleep than lighter gamers. Below ...
Jan. 16, 2026 A new study warns that a widely used eye ointment can damage a popular glaucoma implant. Researchers found that oil-based ointments can be absorbed into the implant’s material, causing it to swell and sometimes break. Patient cases showed damage ...
Jan. 16, 2026 A vitamin A byproduct has been found to quietly disarm the immune system, allowing tumors to evade attack and weakening cancer vaccines. Scientists have now developed a drug that shuts down this pathway, dramatically boosting immune responses and ...
Jan. 15, 2026 Tryptophan does far more than help us sleep—it fuels brain chemistry, energy production, and mood-regulating neurotransmitters. But as the brain ages or develops neurological disease, this delicate system goes awry, pushing tryptophan toward ...
