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...

Ion channels ensure the heart keeps time The heartbeat is the result of rhythmic contractions of the heart muscle, which are in turn regulated by electrical signals called action potentials. Action potentials result from the controlled flow of ions into heart muscle cells (depolarization) through channels in their membranes, and are followed by a compensating reverse ion current (repolarization), which restores the original state. If the duration of the repolarization phase is not just...

A gene that governs the flow of potassium in and out of cells in blood vessels could provide a new avenue for controlling blood pressure, said researchers from Baylor College of Medicine in a report in the current issue of the journal Hypertension. The gene, known as K2P6.1 or TWIK-2, is one of a family of potassium channel genes first discovered in the 1990s. In general, ion channels are tiny pores that, when opened, allow charged ions such as sodium, potassium or calcium to flow in and...

Today someone in a remote village in India is able to run an electrocardiogram (ECG) via their smart phone on a loved one having a potential heart attack and send to a doctor in New Delhi for analysis. Mobile technology is already bringing health care to places it has never been able to reach. However, there is still room for error that can lead to misdiagnosis. Xiaopeng Zhao, assistant professor in the Department of Mechanical, Aerospace and Biomedical Engineering at the University of...

As the gatekeepers of ion flow through cell membranes, ion channels are of key interest in numerous cellular processes. Now, a new study describes an innovative new computational model that realistically simulates the complex conditions found in biological systems and allows for a more accurate look at ion channel function at the level of individual atoms. The research, published by Cell Press in the August 17th issue of the Biophysical Journal, provides a remarkably detailed look at the...

An unexpected discovery has led scientists to open an intriguing new window into the human brain, via the visual system. Their finding may have implications for better understanding of states such as sleep, epilepsy and anaesthesia say the research team leaders Dr Sam Solomon and Professor Paul Martin of The Vision Centre and The University of Sydney. Potentially it could open up a new pathway for manipulating brain rhythms to manage disorders such as insomnia and epilepsy, the team speculate...

(Ivanhoe Newswire) -- A new technique that stimulates heart muscle cells with low-energy light raises the possibility of a future light-controlled pacemaker, according to this study. "Electronic cardiac pacemakers and defibrillators are well established and successful technologies, but they are not without problems, including the breakage of metal leads, limited battery life and interference from strong magnetic fields," Emilia Entcheva, Ph.D., senior author of the study and associate...

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...

attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
