Sea Slugs Inspire New Brain Implant Technology

Findings could apply to people with Parkinson's and spinal cord injuries

(Newser) - Sure, it’s a warty creepy-crawly that lurks at the bottom of the ocean, but the sea cucumber has inspired scientists to create a new material that could be used in implanted brain electrodes to help people with Parkinson’s disease, reports the BBC. The creature stiffens its skin when...

Mind-Reading Edges Closer to Reality

New computer can determine what you're looking at

(Newser) - Mind-reading has taken a step toward possibility with a new computer that can decode brain activity to determine what a person is looking at with up to 90% accuracy, the Independent reports. With improvements, the technology could be able to reconstruct any image a person could conjure up—and someday,...

A.I. Will Match Human Brain in 20 Years

But nanobots in our neurons will make us smarter, too

(Newser) - One engineer and futurist says it’s only a matter of time before machines are as smart as people, and people are part machine, the BBC reports. Ray Kurzweil claims that artificial intelligence will produce human-level smarts and even emotions by 2029. Humans, meanwhile, will inject nanobots into their brains...

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...

Top 10 Mysteries of the Mind

From memories to sleep to consciousness itself, scientists still can't agree

(Newser) - Debated for centuries, the human mind still holds a mystery or two in modern times. Here are LiveScience's top 10:
  1. Consciousness. Still the biggest human puzzle since Socrates.
  2. Cryonics. Can gray matter be revived from a 320-degree deep freeze?
  3. Aging. An unappreciated benefit, or simply cell decay with no purpose?

'Google Man' Never Forgets

Cal-Irvine researchers examining his remarkable recall

(Newser) - Give Brad Williams a date—say, Jan. 1, 1962. He’ll tell you on that Monday his mother worked on the calendar while he watched To Tell The Truth. Sound amazing? Williams’ very rare detailed memory is called hyperthymesia, and University of California at Irvine scientists are studying his brain...

Hospital Fined for Year's Third Botched Brain Surgery

Rhode Island state officials order new safety procedures

(Newser) - State health officials fined Rhode Island Hospital yesterday and ordered it to change procedures after a surgeon began operating on the wrong side of a woman's head, the Providence Journal reports. A patient died after a similar incident four months ago. Yesterday's incident is the third botched neurosurgical procedure this...

Gene Therapy for Parkinson's Delivers Major Results

Researchers find dramatic improvement

(Newser) - New evidence indicates that the first gene therapy for Parkinson's disease has achieved measurable success. Brain scans of patients receiving the treatment confirmed significant changes, supporting earlier anecdotal accounts of 65% improvements in mobility and other gains, according to a study published in the Proceedings of the National Academy of ...

Unruly Kids Don't Do Worse in School

Studies show many youngsters grow out of behavior problems

(Newser) - In what will surely be balm to desperate parents—and an annoyance to school administrators—the New York Times pairs two new studies that find kids with early behavior problems may be more likely to grow out of them than is commonly thought. In one, researchers looked at over 16,...

Brains of ADHD Kids Mature Later: Study

Cortex controlling action and attention lags three years behind

(Newser) - The brains of hyperactive children appear to develop more slowly than those of their peers,  researchers have discovered, with the cortex—the area that affects attention and action— maturing 3 years later than in other children. The finding accounts for the fact that many kids with ADHD grow out...

Scientists Find Eternal Sunshine Spot in Your Mind

Study: Brain section thinks happy thoughts

(Newser) - If you think the glass is half empty, you’re a pessimist—but if you think it’s half full, you have strong activity in your rostral anterior cingulate cortex. That’s the section of the brain, located right behind the eyes, that controls optimism, according to a new study...

Old Doesn't Mean Crotchety, Whippersnapper

Study finds 'negative bias' erodes with age

(Newser) - Aging might cause the memory to, er, lapse, but it also can create a more positive outlook, reports Science. We tend to have a "negative bias"—an inclination to pay more attention to bad news than good—which is reversed as we age. Young people's brain activity jumps...

Heart Meds May Work Against Alzheimer's

Anti-cholesterol drugs appear to combat brain disease

(Newser) - The best medicine for Alzheimer's disease may be a heart drug, researchers say, and the discovery may shed light on the way the devastating disorder acts on the brain. Subjects taking popular statin-based cholesterol meds developed fewer protein deposits in their brains, reports Time, possibly confirming suspicions that Alzheimer’s...

Brain Implant Shows Promise for Stroke Victims

Electrical stimulations helps organ rewire itself

(Newser) - Stroke patients have shown lasting, "extremely promising" results, even years after suffering a brain hemorrhage, from an experimental therapy that electrically stimulates the brain. The currents help the organ rewire itself to take over for stroke-damaged sections, Newsweek reports, and study participants have improved significantly beyond what they could...

Scientists Find Switch to Turn On Brain Cells

Breakthrough could treat mental disorders

(Newser) - Neuroscientists are experimenting with switching targeted groups of brain cells on and off using remote-controlled lasers, promising hope for treatment of mental disorders, reports the New York Times. The technique, using cells altered with a photo-sensitive protein called channelrhodopsin-2, could one day be used to treat a host of problems...

Woman Has Pencil Removed From Brain After 55 Years

Carry your pencils eraser-side up!

(Newser) - A German woman had a pencil removed from her brain after living with it for 55 years. Margret Wegner fell down while holding a pencil when she was four years old, jamming it into her brain and leading to a lifetime of headaches and nosebleeds. Surgeons finally removed most of...

2 Studies Tie Dopamine to ADHD

Low level of brain chemical connected to substance abuse, too

(Newser) - Levels of dopamine—a brain chemical associated with movement and emotion—may explain the occurrence of attention deficit and hyperactivity, two studies published yesterday concluded. The studies found decreased dopamine activity in the brains of individuals, both children and adults, diagnosed with ADHD. Doctors say these decreased levels could have...

Electric Stimulation Revives Man in Near-Coma

Case brings hope, raises questions

(Newser) - Electric stimulation may help improve the brain function of patients in a minimally conscious state, a case study reported in Nature reveals. A 38-year-old man who was mute and barely conscious for nearly 6 years is able to name objects, perform precise movements, and eat without the aid of a...

The Mind Thinks More Than It Knows

Subconscious works behind the scenes of decisions, judgments

(Newser) - After just handling a stranger’s coffee, people make subconscious judgments about personality, psychologists say.

The experiment is part of a body of research that leads...

No Tired Explanation: Yawning May Cool Brain

Evolutionary adaptation keeps the nervous system's motherboard cool

(Newser) - Yawning may be less a response to boredom than a natural mechanism for cooling off overheated brains, new research says. The human brain operates optimally when cool, much like a computer, and conditions like fatigue actually cause the organ to heat up, ABC News reports. A quick gulp of air...
