The incubation period is about 100ms, the polarity was negative (N100), followed by the positive elements for the 2001TIS (P200ms). The greater the stimulus intensity, the higher the volatility, the shorter the incubation period. Repeated if the same intensity stimulus, the longer the interval, the higher the volatility of the same, the shorter the incubation period, therefore, is a habit with potential selection. vertexsharptransiet top wave has also been called the V wave slightly (not recommended), the Department of stimuli during sleep occur spontaneously or sharp waves, sustained 5O ~ 200ms, amplitude of 250V below, the total head at the top of the tracings to the volatility of the highest, hence the name. But in children, often at the top of the forehead is higher than volatility in general is a negative phase for the wave, but it is also positive is a negative phase of a wave or a single transient wave can be repeated, mainly seen in non-rapid eye movement sleep Ⅱ, and sometimes I can be found in or Ⅲ. Children's easy to see that the elderly are rare, but adults can also be found sleeping. Bipolar lead in the sagittal chain, in C. , C before and after phase inversion. Therefore,[link widoczny dla zalogowanych], the tracings of the night, do not be such a wave as the epileptic discharge. visualevokedpotential (VEP) visual evoked potential when given visual stimulus, recorded in the occipital series of potential changes. However,[link widoczny dla zalogowanych], because of stimulation intensity, stimulation frequency, the light color of change recorded by a great potential, coupled with this potential itself is not stable, individual differences, and the Othello disk format change evoked P100 wave, sub-field of vision stimulation on visual pathway function orientation useful. As for the meaning of a certain series of graphic color stimuli, are the event-related] O2 · potential scope of the study. visualevokedresponse (VER) VEP visual evoked response and synonymous priority VEP. voltage range of voltage in neural electrophysiology refers to the tracings of the potential difference between two electrodes, the specific level of the volatility reflected in the computer can be directly read out. wicketrhythm arches, also known as the arcuate-shaped rhythm rhythm rhythm comb, fence-like rhythm, but are not very precise, recommended mu (g) rhythm. writer refers to the monitor tracing paper record electrophysiological tracings part of the mechanical device. The principle is built on a permanent magnet cylinder front-line package, driven by the amplified electric signal line package from side to side, the line package also will be connected to swing around the axis, the axis of the rod (inking pen) around the paper plane swing up and down the baseline to draw a continuous wave map is a variety of electrophysiological signals map. Used to adjust the scanning pen is just to good contact with the paper and ink to draw lines to smooth. Pen on paper, the pressure too light, can break the line tracings, heavy blunt is the waveform distortion. Mostly currently used computerized equipment, through observation screen, the monitor is not that. zeropotentialreferenceelectrod zero potential reference electrode tracings of the electrophysiologic point of the two electrode potential difference between the relative change in practice is difficult to find a true zero potential point, there is no need to look for, so do not recommend using a qualifier, with the (Zhang Wenyuan compilation)
