Life in Technicolor II
"Life in Technicolor II" (properly spelled and written as "Life in Technicolor ii"), is a song by British alternative rock band Coldplay and the first single from the band's 2008 EP, Prospekt's March. The song is the full, vocal version of the instrumental song "Life in Technicolor" from Coldplay's fourth studio album, Viva la Vida or Death and All His Friends. A promo CD single for the song was released in December 2008. The official single was released on 2 February 2009 on 7" vinyl and digital download. The single includes the previously unreleased and unheard track "The Goldrush", one of the few Coldplay songs featuring lead vocals by drummer Will Champion. It was nominated for two Grammy Awards for the 52nd Grammy Awards; "Best Rock Performance by a Duo or Group with Vocal" and "Best Short Form Music Video".
"Life in Technicolor ii" starts with a loop consisting of a yangqin accompanied by tabla-like percussion. The loop is then repeated through the verses and part of the chorus.
Evoked potential
An evoked potential or evoked response is an electrical potential recorded from the nervous system of a human or other animal following presentation of a stimulus, as distinct from spontaneous potentials as detected by electroencephalography (EEG), electromyography (EMG), or other electrophysiological recording method.
Evoked potential amplitudes tend to be low, ranging from less than a microvolt to several microvolts, compared to tens of microvolts for EEG, millivolts for EMG, and often close to a volt for ECG. To resolve these low-amplitude potentials against the background of ongoing EEG, ECG, EMG, and other biological signals and ambient noise, signal averaging is usually required. The signal is time-locked to the stimulus and most of the noise occurs randomly, allowing the noise to be averaged out with averaging of repeated responses.
Signals can be recorded from cerebral cortex, brain stem, spinal cord and peripheral nerves. Usually the term "evoked potential" is reserved for responses involving either recording from, or stimulation of, central nervous system structures. Thus evoked compound motor action potentials (CMAP) or sensory nerve action potentials (SNAP) as used in nerve conduction studies (NCS) are generally not thought of as evoked potentials, though they do meet the above definition.
