Ultrasound May Help Counter Brain Disease

Low frequency ultrasound shown to release neurotransmitters

(Newser) - Bombarding the brain with sound waves may not seem like the most logical way to repair damage, but a new study shows that ultrasound may have therapeutic uses, reports the Economist. While ultrasound technology has long been used to take images of human interiors, such as fetuses in the womb,...

Japanese Scientists Can Read Your Mind

They find a way to extract images directly from the brain

(Newser) - The Thought Police could eventually exist in reality, if they can just figure out how to harness new technology developed by Japanese researchers, the Daily Yomuri reports. The team managed to re-create images that people were looking at—using only subjects' recorded brain activity. This is the first successful display...

Vitamin Could Delay Onset of Alzheimer's

B3 pills caused big improvement in mice; human trials to begin

(Newser) - A simple dose of vitamin B3 may be one of the keys to combating the brain deterioration caused by Alzheimer’s disease, California scientists say. The team found that diseased mice given high levels of the vitamin retained normal memory ability over the four months of a study, and healthy...

Autism-Reversing Drugs Show Promise

MIT scientists stumbled onto workaround for misfiring brain system

(Newser) - MIT scientists have discovered one of the mechanisms of Fragile X Syndrome, one cause of autism, and are developing drugs to treat it, NPR reports. The disorder, triggered by a genetic mutation, interferes with the normal links between brain cells, making those networks something like a car without a brakes....

Brain Doesn't Remember Events—It Relives Them

Study records evidence supporting long-suspected memory pathway

(Newser) - Scientists for the first time have observed how brain cells drum up a memory, and the findings buttress the notion that our minds don't so much remember events as relive them. When recalling short film clips they had seen, patients' brains repeated the same pattern of neuron activity they experienced...

Study Yields More Clues About Autism

Scientists find genes needed for learning stuck in the off position

(Newser) - Scientists have found six new genes linked to autism, inching closer to a fuller understanding of the disorder and how to treat it, the AP reports. The genes in question are necessary for learning but are essentially stuck in the "off" position. The finding lends credence to the philosophy...

Chronic Pain Rewires the Brain

Researchers find suffering constant pain can cause permanent changes

(Newser) - Researchers studying the brains of people suffering from chronic pain have found that  an area of their cortex is permanently active when it should sometimes deactivate, Reuters reports. That part of the brain, usually associated with emotion, stays on "full throttle" at all times. Researchers say this could explain...
