Maybe some green can help alleviate the migraine?

Green light reduces migraine headaches

Migraine headaches, or migraines, are defined as an intense throbbing or a pulsing sensation in one area of the head, usually with nausea, vomiting, and sensitivity to light and sound. Migraines are prevalent globally, as 30% or more people worldwide who struggle with headaches report suffering from migraines. Although migraines themselves are not lethal (if […]

Tylenol and other paracetamol painkillers may hinder the brain’s error-correction mechanisms




It’s been known for more than a century that acetaminophen (also known as paracetamol and marketed as Tylenol and Panadol) is an effective painkiller, but according to a new Canadian study it could also be impeding error-detection in the brain. The research appears in the journal Social Cognitive and Affective Neuroscience. “Past research tells us physical […]

fMRI data trove yields new insights into consciousness and abstract thought




Using 20 years of functional magnetic resonance imaging (fMRI) data from tens of thousands of brain imaging experiments, neuroscientists at the University of Massachusetts have created a geometry-based method for massive data analysis to reach a new understanding of how thought arises from brain structure. The research, appearing in the current issue of Nature Scientific […]

Brain inflammation linked to compromised reward circuits in depression




Around one third of people with depression have high levels of inflammation markers in their blood. Now, new research appearing in in Molecular Psychiatry shows that persistent inflammation affects the brain in ways that are connected with stubborn symptoms of depression, such as anhedonia (the inability to experience pleasure). The findings bolster the case that […]

New technique for thought-controlled data input almost as accurate as one-fingered typing




When we type or perform other precise tasks, our brains and muscles usually work together effortlessly. But when a neurological disease or spinal cord injury severs the connection between the brain and limbs, once-easy motions become difficult or impossible. In recent years researchers have sought to give people suffering from injury or disease some restored […]

Stimulant drug abuse appears to reduce brain volume in women but not men




Using MRI to study the brains of cocaine and meth users, researchers found that while the women demonstrated widespread brain differences when compared to their healthy control counterparts, the men demonstrated no significant brain differences. The findings from the study appear in the journalRadiology. “We found that after an average of 13.5 months of abstinence, […]

Blind human echolocators can recognize the shape, size, and material properties of objects, according to new study




New Canadian research into human echolocation suggests that as well as being able to locate objects, some blind people can also discern the shape and texture of those objects. The new findings, presented last week at the 9th Annual Canadian Neuroscience Meeting in Vancouver, build onprevious work from the UK that established some of the […]

Video game link to Alzheimer’s?




Video gamers spend a collective three billion hours per week in front of their screens. And while the average young person will have spent 10,000 hours gaming by the time they are 21, the effects of video gaming on the brain are only beginning to be understood. Now, a new study published in the journalProceedings […]

Premature birth alters key brain connections




New research from King’s College London sheds light on why premature birth is linked to a greater risk of neurodevelopmental problems, including autistic spectrum disorders and attention deficit disorders. The new work, published in the journal PNAS, used functional magnetic resonance imaging to establish that premature birth can alter connectivity between key areas of the […]

Mars astronauts will suffer significant brain damage




Scientists at the University of California, Irvine have been investigating what might happen to an astronaut’s brain during the long journey to Mars and found that constant exposure to highly energetic charged particles – much like those found in the galactic cosmic rays that bombard astronauts during extended spaceflights – cause significant damage to the […]
