Arthritis pain processed in parts of brain concerned with emotions and fear

Researchers at The University of Manchester have discovered that arthritis pain, unlike that induced as part of an experiment, is processed in the parts of the brain concerned with emotions and fear.

Role of emotions in how patients feel arthritis pain

How does the brain process the experience of pain? Thanks to advances in neuroimaging, we now know the answer lies in a network of brain structures called the pain matrix.

Glimpse into early brain development shows how nerve cells move into position

Tucked into the lower, rear portion of the brain, the cerebellum plays key roles in motor learning, motor memory and sensory perception. It's also where the majority of metastatic childhood brain tumors are located. Yet scientists still know very little about its early growth.

Chemical cues turn embryonic stem cells into cerebellar neurons

Embryonic stem cells have shown a great deal of promise for alleviating heart disease and regenerating organs. But for some of the conditions for which people hold out the most hope - Alzheimer's and Parkinson's, for example - there's been little evidence to date that stem cells can work.

Clinical and imaging evidence of Zolpidem effect in hypoxic encephalopathy

A new study reported that zolpidem, a drug normally used to treat insomnia, temporarily improved brain function in a patient suffering from akinetic mutism, a condition in which the person is alert but cannot speak or move.

Scientists answer brain mystery

The taste of champagne, the sound of a train, the flash of a pop fly into left field - indeed all of human perception ' begins in the brain's center. That's where sensory information passes from the thalamus to the neocortex for processing.

Rare cell prevents rampant brain activity

One of the mysteries of the brain is how it avoids ending up in a state of chaos, something which happens only on exceptional occasions, when it can lead to epileptic fits.

Bionic eye offers light at the end of the tunnel for the blind

Researchers in the United States have been given the green light by the Food and Drug Administration (FDA) to trial a bionic eye implant in blind patients.

Nicotine addiction depends on a healthy insula

Smokers with a damaged insula - a region in the brain linked to emotion and feelings - quit smoking easily and immediately, according to a study in the Jan. 26 issue of the journal Science.

HRT shows promise in helping visual memory of postmenopausal women

Many women experience declines in their memory during and after menopause, a change thought to be due, in part, to the rapid hormonal changes they weather during that time.

Scientists spot mechanism behind promising new sleep drug

An experimental drug called gaboxadol may soon help millions of bleary-eyed insomniacs get to sleep, and a multi-center team of U.S. scientists believes they've pinpointed just how the drug works.

Implantable chip to establish new nerve connections in brain area that controls movement

Researchers at the University of Washington (UW) are working on an implantable electronic chip that may help establish new nerve connections in the part of the brain that controls movement.

Parkinson's disease affects more than just motor control

Although Parkinson's disease is most commonly viewed as a "movement disorder," scientists have found that the disease also causes widespread abnormalities in touch and vision - effects that have now been verified using functional magnetic resonance imaging (fMRI) of the brain.

Researchers find areas in the brain that indicate bilingualism

The finding sheds new light on decades of debate about how the human brain's language centers may actually be enhanced when faced with two or more languages as opposed to only one.

Scans reveal differences in autistic brains

Researchers at the University of Washington's Autism Center have found new evidence that some regions in the brains of people with the developmental disorder autism may not communicate with each other as efficiently as they do in other people.

Cocaine addicts have an altered perception of reward

People addicted to cocaine have an impaired ability to perceive rewards and exercise control due to disruptions in the brain's reward and control circuits, according to a series of brain-mapping studies and neuropsychological tests conducted at the U.S. Department of Energy's Brookhaven National Laboratory.

Food like an addictive drug for some people

Researchers in the U.S. have found that the same brain circuits are involved when obese people fill their stomachs as when drug addicts think about drugs and the discovery they say suggests an association between overeating and addiction.
