Penn-led team develops microelectronic device to map brain activity A team of researchers co-led by the University of Pennsylvania has developed and tested a new high-resolution, ultra-thin device capable of recording brain activity from the cortical surface without having to use penetrating electrodes. The device could make possible a whole new generation of brain-computer interfaces for treating neurological and psychiatric illness and research. The work was published in Nature...

Ultrathin Flexible Brain Implant Offers Unique Look At Seizures
2011-11-14 05:19:10

Researchers funded by the National Institutes of Health have developed a flexible brain implant that could one day be used to treat epileptic seizures. In animal studies, the researchers used the device — a type of electrode array that conforms to the brain's surface — to take an unprecedented look at the brain activity underlying seizures. "Someday, these flexible arrays could be used to pinpoint where seizures start in the brain and perhaps to shut them down," said Brian...

The future of drug design lies in developing therapies that can target specific cellular processes without causing adverse reactions in other areas of the nervous system. Scientists at the Universities of Bristol and Liège in Belgium have discovered how to design drugs to target specific areas of the brain. The research, led by Professor Neil Marrion at Bristol´s School of Physiology and Pharmacology and published in this week´s Proceedings of National Academy of...

Scientists Achieve Precise Control Of Virtual Flight

Scientists have designed a novel, noninvasive system that allows users to control a virtual helicopter using only their minds, as reported in the online journal PLoS ONE on Oct. 26. The researchers, led by Dr. Bin He of University of Minnesota, created an EEG-based, noninvasive brain-computer interface that allowed users to accurately and continually navigate a virtual helicopter simply by thinking about where they wanted to craft to go. The task required users to direct their helicopter...

Potential mechanism for dazzling blue flashes of light in oceans identified It has long been known that distinctive blue flashes--a type of bioluminescence--that are visible at night in some marine environments are caused by tiny, unicellular plankton known as dinoflagellates. However, a new study has, for the first time, detailed the potential mechanism for this bioluminesence. The study, which was partially funded by the National Science Foundation, is reported by Susan Smith of Emory...

Rhythmic activity of neurons to code position in space Prof. Dr. Motoharu Yoshida and colleagues from Boston University investigated how the rhythmic activity of nerve cells supports spatial navigation. The research scientists showed that cells in the entorhinal cortex, which is important for spatial navigation, oscillate with individual frequencies. These frequencies depend on the position of the cells within the entorhinal cortex. "Up to now people believed that the frequency is...

Electrocardiography
2013-04-30 09:55:53

Electrocardiography, sometimes called ECG or EKG, is a measurement of the electrical activity of the heart as the linear process unfolds. With the use of electrodes that are attached to the skin, this non-invasive test can provide vast information as to the patient’s status. By leaving the electrodes attached, the patient’s status can be monitored over intervals of time and recorded on the device. This data can be sent electronically for consults about potential treatments without delay....

Electrooculography

Electrooculography, sometimes shortened to EOG, is the tracing of electricity used for operation of the retina in different phases, specifically the resting potential. The results are recorded on an electrooculogram. These are interpreted for opthalmological diagnosis and in recording eye movements. Eye movement measurements: Usually, pairs of electrodes are placed either above and below the eye or to the left and right of the eye. If the eye is moved from the center position towards one...

Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
