Authors disagree on real cost of screening While ensuring the safety of high school and college athletes is hardly controversial, the method and associated costs of doing so are hotly debated. Conducting electrocardiographic (ECG) screenings of all young competitive athletes in the United States would cost up to $69 billion over 20 years and save about 4,813 lives, making the cost per life saved over $10 million, according to a study published online today in the Journal of the American...

Brain Waves And The Neural Basis Of Consciousness
2012-11-22 07:00:49

April Flowers for redOrbit.com - Your Universe Online How our brains encode thoughts, such as perceptions and memories, at the cellular level is one of the biggest puzzles in neuroscience today. One theory suggests that ensembles of neurons represent each unique piece of information. No one knows, however, just what these ensembles look like, or how they form. A new study, published in a recent issue of Neuron, sheds light on how neural ensembles form thoughts and support the...

Synthetic Membrane Channels Built Out Of DNA
2012-11-21 08:03:43

Technische Universitaet Muenchen Nanotech structures mimic nature's way of tunneling through cell walls As reported in the journal Science, physicists at the Technische Universitaet Muenchen (TUM) and the University of Michigan have shown that synthetic membrane channels can be constructed through "DNA nanotechnology." This technique employs DNA molecules as programmable building materials for custom-designed, self-assembling, nanometer-scale structures. The researchers present evidence...

Brain Waves Translated Into Music
2012-11-15 21:48:46

Brett Smith for redOrbit.com — Your Universe Online Chinese researchers at the University of Electronic Science and Technology in Chengdu, China have developed a method to transform brain waves into music that closely resembles something a human composer would write. According to their report in the open access journal PLOS ONE, they were able to use an electroencephalogram (EEG) to create the pitch and duration of a note, and functional magnetic resonance imaging (fMRI) to...

Researchers Investigate The Listening Brain
2012-11-15 12:27:25

Max-Planck-Gesellschaft Listening abilities depend on rhythms in the brain Naturally, our brain activity waxes and wanes. When listening, this oscillation synchronizes to the sounds we are hearing. Researchers at the Max Planck Institute for Human Cognitive and Brain Sciences have found that this influences the way we listen. Hearing abilities also oscillate and depend on the exact timing of one´s brain rhythms. This discovery that sound, brain, and behavior are so intimately...

Brain Shuts Down During Anesthesia
2012-11-06 13:41:09

Lee Rannals for redOrbit.com - Your Universe Online Surgeons have been using general anesthesia since the 19th century, but until now physicians and neurologists didn´t know exactly how brain activity correlates to the loss of consciousness. A new study from Massachusetts General Hospital (MGH) and Massachusetts Institute of Technology (MIT) that was recently published in the journal PNAS demonstrated how distinctive brain activity patterns are associated with the loss of...

Brain's code for visual working memory deciphered in monkeys -- NIH-funded study The brain holds in mind what has just been seen by synchronizing brain waves in a working memory circuit, an animal study supported by the National Institutes of Health suggests. The more in-sync such electrical signals of neurons were in two key hubs of the circuit, the more those cells held the short-term memory of a just-seen object. Charles Gray, Ph.D., of Montana State University, Bozeman, a grantee of...

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
2012-12-31 11:47:45

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...

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.
