Math Can Hurt You—Physically

Just thinking about it hurts, say researchers

(Newser) - Thanks to Barbie, we've long known that math class is tough. But now scientists say just the thought of math can be downright painful, reports Stuff . Researchers used MRIs to measure subjects' brain activity in a variety of hypothetical situations, including "walking to math class" and "receiving... More »

MRI Machines Go Super-Size for Chubbier US

Accommodating obesity 'a design requirement'

(Newser) - As the US gets heavier, makers of MRI machines and other medical scanners are rushing to cope—by literally enlarging their equipment. But for some Americans, the process isn't going fast enough. The Wall Street Journal recounts the story of a 630-pound Maryland mechanic who's been out of... More »

Doctors: Chill With All the MRIs, EKGs

With so much unnecessary testing, doctors try to rein in excess

(Newser) - US doctors need to scale back on 45 of the most common testing procedures and treatments—such as EKGs for physicals when there's no sign of heart trouble, MRIs for routine back pain, and antibiotics for mild sinusitis. A panel of nine medical specialty boards is to make the... More »

Mushrooms May Light Way to Depression Treatment

Psilocybin dampens areas of brain linked to depression, studies suggest

(Newser) - Far out. Hallucinogenic mushrooms' effect on the human brain may provide valuable clues for scientists seeking treatments for depression. Two studies into the effects of psilocybin, the active ingredient in "magic mushrooms," reveal that it suppresses activity in the same areas of the brain dampened by anti-depressant treatments,...

'Silent Strokes' May Damage Memory

About 25% of seniors have had them

(Newser) - "Silent strokes" may be taking a toll on seniors' memory. A new study shows that seniors who have suffered such strokes—they don't have obvious symptoms but leave behind dead brain cells—do worse on memory tests, reports USA Today . It's no small thing: An estimated 1... More »

Women: This Is Your Brain During Orgasm

Bran scan video is first to reveal female fireworks

(Newser) - Here, finally, is a female orgasm in living, gasping color, delivered in a mesmerizing video of brain scans.

Scientists Recreate Movies From Brain Activity

Process could someday let us look in on dreams

(Newser) - Scientists at UC Berkeley have made a major advancement in the field of mind reading, reconstructing YouTube videos based on brain scans from people who’d seen them. Researchers would put subjects into an MRI machine and track their brain activity as they viewed videos. Once they’d build a... More »

Om My! Meditation Changes Brain Structure

Brain scans indicate permanent, positive development

(Newser) - This might already be obvious to enlightened souls, but researchers are discovering that meditation may permanently change the physical structure of the brain. Neural circuits linked to focus, happiness and empathy may be strengthened through long-term meditation, effectively rewiring the brain and "lighting up" certain sections with a life-long... More »

Computers Diagnose Autism From Scans

Program like facial recognition software recognizes signs of disorder

(Newser) - Scientists have taught a computer to recognize autism from a brain scan, and believe that from now on they could use a scan to diagnose the disorder with 90% accuracy.
