Power of alpha wave increases just before the distracter

Alpha waves were long ignored, but gained interest of brain researchers recently. Electrical activity of groups of brain cells results in brain waves with different amplitudes. The so called alpha wave, a slow brain wave with a cycle of 100 milliseconds seems to play a key role in suppressing irrelevant brain activity. The current hypothesis is that this alpha wave is associated with pulses of inhibition (every 100 ms) in the brain.

Anesthetics and protein interactions: an interview with José A. Fernández

For a long time there was a controversy about how anesthetics work. The large number of molecules that have anesthetic properties (from benzodiazepines to nitrous oxide) and their very different structures...

CIB2 gene responsible for progression and severity of Usher syndrome

Usher syndrome is a hereditary disease in which affected individuals lose both hearing and vision. The impact of Usher syndrome can be devastating. In the United States, approximately six in every 100,000 babies born have Usher syndrome.

Lasers manipulate neurons in worms' brains

In the quest to understand how the brain turns sensory input into behavior, Harvard scientists have crossed a major threshold. Using precisely-targeted lasers, researchers have been able to take over an animal's brain, instruct it to turn in any direction they choose, and even to implant false sensory information, fooling the animal into thinking food was nearby.

St. Jude Medical’s Eon family of neurostimulators receives European CE Mark approval

St. Jude Medical, Inc., a global medical device company, today announced it has received European CE Mark approval of its Eon family of neurostimulators for patients with intractable chronic migraine. Unveiled at the European Headache and Migraine Trust International Congress in London, this approval includes the Eon Mini neurostimulator, which is the world's smallest rechargeable neurostimulator with the longest-lasting battery in its class, and the Eon and EonC neurostimulators.

'Deep sleep' intimately involved in complex control of pubertal onset

Slow-wave sleep, or 'deep sleep', is intimately involved in the complex control of the onset of puberty, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology and Metabolism (JCEM).

OptiMedica Catalys Precision Laser System for creating corneal incisions receives FDA 510(k) clearance

Global ophthalmic company OptiMedica Corp. has announced U.S. Food and Drug Administration 510(k) market clearance of its Catalys Precision Laser System for creating single-plane and multi-plane arc cuts/incisions in the cornea during cataract surgery.

Deep-brain stimulation may stop uncontrollable shaking in patients with Parkinson's

Deep-brain stimulation (DBS) may stop uncontrollable shaking in patients with Parkinson's disease and essential tremor by imposing its own rhythm on the brain, according to two studies published recently by University of Alabama at Birmingham researchers in the journal Movement Disorders.

Neurally-interfaced hand prosthesis re-establishes communication between nervous systems

Amputation disrupts not only the peripheral nervous system but also central structures of the brain. While the brain is able to adapt and compensate for injury in certain conditions, in amputees the traumatic event prevents adaptive cortical changes. A group of scientists reports adaptive plastic changes in an amputee's brain following implantation of multielectrode arrays inside peripheral nerves.

Pulvinar regulates communication between clusters of brain cells

A mysterious region deep in the human brain could be where we sort through the onslaught of stimuli from the outside world and focus on the information most important to our behavior and survival, Princeton University researchers have found.

Biomedical engineer devises new noise model that is closer to the biological reality

Biomedical engineer Muhammet Uzuntarla from Bulent Ecevit University, Turkey, and his colleagues present a biologically accurate model of the underlying noise which is present in the nervous system.

Novel device provides retina's neural code to restore normal vision

Two researchers at Weill Cornell Medical College have deciphered a mouse's retina's neural code and coupled this information to a novel prosthetic device to restore sight to blind mice.

Protein folding: Nobel laureate Ahmed H. Zewail summarizes his insights

Living subjects are very complex systems and, at the same time, stunningly robust and accommodative. The secret of success are their proteins which build up the cells of the organisms, act as cleaners, messengers, transporter, motors, and fulfill much more jobs. How proteins are genetically coded and how their linear chains of amino acids are put together, is in principle well known.

Photoacoustics limited in its ability to identify multiple types of cancer

One person dies every hour from melanoma skin cancer in the United States, according to the American Cancer Society. A technique, known as photoacoustics, can find some forms of melanoma even if only a few cancerous cells exist, but a recent study by MU researchers found that the technique was limited in its ability to identify other types of cancer.

New laser technology can non-invasively destruct cancerous tumors

Researchers at the Center for Laser Applications at the University of Tennessee Space Institute in Tullahoma have developed a technology that goes on a "seek and destroy" mission for cancerous tumors. They have harnessed the power of lasers to find, map and non-invasively destruct cancerous tumors.

Second Sight’s Argus II Retinal Prosthesis System scheduled for FDA panel review

Second Sight Medical Products Inc., the world's leading developer and manufacturer of retinal prostheses, today announced that a U.S. Food and Drug Administration (FDA) Ophthalmic Devices Advisory Panel has been scheduled to review the data presented in the company's Humanitarian Device Exemption (HDE) market approval application for its Argus II Retinal Prosthesis System (Argus II prosthesis) on September 28, 2012 in Gaithersburg, Maryland.

Scientists capture high-quality images of immune cell trafficking in a beating heart

Blood flow to the heart often is interrupted during a heart attack or cardiac surgery. But when blood flow resumes, the heart may still falter. That's because collateral damage can occur as blood re-enters the heart, potentially slowing recovery and causing future cardiac troubles.
