which technique measures the electrical activity of brain cells directly
Electroencephalography ( EEG )
Electroencephalography Electroencephalography (EEG) is an electrophysiological monitoring method to record electrical activity of the brain. It is typically noninvasive, with the electrodes placed along the scalp, although invasive electrodes are sometimes used such as in electrocorticography. EEG measures voltage fluctuations resulting from ionic current within the neurons of the brain. In clinical contexts, EEG refers to the recording of the brain's spontaneous electrical activity over a period of time, as recorded from multiple electrodes placed on the scalp. Diagnostic applications generally focus either on event-related potentials or on the spectral content of EEG. The former investigates potential fluctuations time locked

as a complete, unbiased attention to the current moment. Electroencephalography (EEG) has been used in many studies as a primary method for evaluating the meditating brain. Electroencephalography uses electrical leads placed all over the scalp to measure the collective electrical activity of the cerebral cortex. Specifically, EEG measures the electric fields of large groups of neurons. EEG has the benefit of excellent temporal resolution and is able to measure aggregate activity of portions or the entire cortex down to the millisecond scale. Unlike other imaging based methods, EEG does not have good spatial resolution and is more appropriately used to

Brain fingerprinting Brain fingerprinting is a lie detection technique which uses electroencephalography (EEG) to determine whether specific information is stored in a subject's brain. The technique consists of measuring and recording a person's electrical brainwaves and brain response when asked questions about a crime, attempting to elicit a "P300 response" that indicates familiarity with the details of the crime. The technique is controversial, unproven and of questionable accuracy. Comparison of brain fingerprinting with polygraphy showed mixed results consistent with "a mix of proven techniques and dangerously exaggerated benefits". Brain fingerprinting was invented by Dr. Lawrence Farwell. In 2001, the technique

advancement with the discovery of the P3 component. Over the next fifteen years, ERP component research became increasingly popular. The 1980s, with the introduction of inexpensive computers, opened up a new door for cognitive neuroscience research. Currently, ERP is one of the most widely used methods in cognitive neuroscience research to study the physiological correlates of sensory, perceptual and cognitive activity associated with processing information. ERPs can be reliably measured using electroencephalography (EEG), a procedure that measures electrical activity of the brain over time using electrodes placed on the scalp. The EEG reflects thousands of simultaneously ongoing brain processes. This

'brainwaves' in common parlance. The technique of recording neural electrical activity within the brain from electrochemical readings taken from the scalp originated with the experiments of Richard Caton in 1875, whose findings were developed into electroencephalography (EEG) by Hans Berger in the late 1920s. The functional role of neural oscillations is still not fully understood; however they have been shown to correlate with emotional responses, motor control, and a number of cognitive functions including information transfer, perception, and memory. Specifically, neural oscillations, in particular theta activity, are extensively linked to memory function, and coupling between theta and gamma activity is

James Heidinger. The movement has been very successful in maintaining doctrinal standards and traditional United Methodist positions on theology and practice at the General Conferences in Cleveland (2000), Pittsburgh (2004), and Ft. Worth (2008). At the 2008 conference for instance delegates voted to retain language in the Social Creed defining marriage as a union between one man and one woman. They also maintained the traditional teaching, that although homosexuals "are individuals of sacred worth", homosexual practice is "incompatible with Christian teaching." Other organizations aligned with The Confessing Movement within The United Methodist Church include Concerned Methodists, Good News, United Methodist

The Frutiger family was released publicly in 1976 by the Stempel type foundry in conjunction with Linotype. Frutiger's simple and legible yet warm and casual character has made it popular today in advertising and small print. Some major uses of Frutiger are in the corporate design of Raytheon, PharMerica, O, the British Royal Navy and British Army, the London School of Economics and Political Science, Deutsche Post and its subsidiary DHL Express, the Canadian Broadcasting Corporation, the Conservative Party of Canada, the Banco Bradesco in

when talkshow host Jerry Springer played some live footage of their song "Jerry Rules In The Land Of The Free". In this song, taken from their album SCHIZO, Heideroosjes voiced their opinion on (semi-reality) TV shows like "The Jerry Springer Show". Heideroosjes toured (mainly) Europe with familiar bands like The Offspring, Pennywise, The Misfits, Bad Religion and Less Than Jake. In 2004, the Heideroosjes tour bus was involved in a serious accident. Three roadies were wounded, and one roadie was seriously injured. The band cancelled their tour but continued a few weeks later. Later that year, Heideroosjes received some sort

quality forage, and with increasing body mass animals are less selective. Several theories attempt to explain and quantify the relationship between animals and their food, such as Kleiber's law, Holling's disk equation and the marginal value theorem (see below). Kleiber's law describes the relationship between an animal's size and its feeding strategy, saying that larger animals need to eat less food per unit weight than smaller animals. Kleiber’s law states that the metabolic rate (q) of an animal is the mass of the animal (M) raised to the 3/4 power: q=M Therefore, the mass of the animal increases at a

difficult situations they were in. Recalling the song in 2013, Mangeshkar stated that she never expected the song to be so successful saying, "Since it was not part of a film, I thought it would have a limited impact. "Ae mere watan ke logon" became my signature tune. No show of mine, no concert or event is complete until I sing it." She also stated that Pradeep was always sure of the song's success saying, "Only Pradeepji had faith in the song. He had prophesied to me, 'Lata, tum dekhna yeh gaana bahot chalega.

(i.e., surgical ablation of the globus pallidus) or thalamotomy (i.e., surgical ablation of the thalamus). Instead, a thin lead with multiple electrodes is implanted in the globus pallidus, nucleus ventralis intermedius thalami, or subthalamic nucleus, and electric pulses are used therapeutically. The lead from the implant is extended to the neurostimulator under the skin in the chest area. Its direct effect on the physiology of brain cells and neurotransmitters is currently debated, but by sending high-frequency electrical impulses into specific areas of the brain, it can mitigate symptoms and directly diminish the side effects induced by PD medications, allowing a

as brain electrical activity mapping or BEAM ) The heart is the muscle that pumps oxygenated blood to the whole body. As a very active muscle, it has peculiar electrical activity that can be measured and analyzed. Electrocardiography is the measurement of these signals. Electromyography is the measurement and analysis of the electrical activity in skeletal muscles. This technique is useful for diagnosing the health of the muscle tissue and the nerves that control them. EMG measures action potentials, called Motor Unit Action Potentials (MUAPs), created during muscle contraction. A few common uses are determining whether a muscle is active

this is the case for VMAT1. Heterotrimeric G-protein Gαo2 decreases VMAT1 activity in pancreatic and adrenal medulla cells, and activates heterotrimeric G-proteins inhibit VMAT2 activity in the brain, regardless of whether localised on small clear-core or large-dense-core vesicles. Activated heterotrimeric G-protein Gαq downregulates VMAT2 mediated serotonin transport in blood platelets, but this is not the case in the brain where Gαq inhibits VMAT2 activity completely. Although the exact signalling pathway for G-protein mediated regulation of VMATs is not known, it has recently been described that implicated G-proteins act directly on the VMATs themselves. VMAT2 has been shown to contribute to

Fetal EEG Fetal electroencephalography, also known as prenatal EEG includes any recording of electrical fluctuations arising from the brain of an unborn child. Doctors and scientists use EEGs to detect and characterize brain activity, such as sleep states, potential seizures, or levels of a coma. EEG captures the electrical activity in the vicinity of the recording electrodes. The majority of the neural electrical activity arises from the flow of current from the cell bodies of pyramidal neurons to their apical dendrites, which become depolarized by excitatory inputs from other neurons. To record the most accurate signals, scientists try to minimize

established itself as the most reliable laboratory method for counting a wide variety of cells, ranging from bacteria (< 1 micrometre in size), fat cells (~400 micrometre), plant cell aggregates (>~1200 micrometre), and stem cell embryoid bodies (~900 micrometre). The technique has become so standardized that ASTM International has published a procedure on the topic: "ASTMF2149-01(2007) Standard Test Method for Automated Analyses of Cells-the Electrical Sensing Zone Method of Enumerating and Sizing Single Cell Suspensions". The Coulter Principle has proved useful for applications well beyond cellular studies. The fact that it individually measures particles, is independent of any optical properties,
