  • brain potentials
  • In the last decade it has become quite evident that eventrelated brain potentials not only reflect changes in the physical parameters of a stimulus but are also quite sensitive to psychol ogical variables. (springer.com)
  • Donchin, E., 1980, Event-related brain potentials: a tool in the study of human information processing. (springer.com)
  • neurologists
  • this book makes an enjoyable reading for those that use some form of auditory evoked potentials for their clinical or research work and are interested in learning about other aspects of such a widespread subject involving neurologists, physiologists, psychologists, neuro-otologists and other specialists and researchers in the field.

  • stimulation
  • visual evoked potentials, and somatosensory evoked potentials , which are elicited by electrical stimulation of peripheral nerve. (wikipedia.org)
  • By analogy with the steady-state response of a resonant circuit that follows the initial transient response he defined an idealized steady-state evoked potential (SSEP) as a form of response to repetitive sensory stimulation in which the constituent frequency components of the response remain constant with time in both amplitude and phase. (wikipedia.org)
  • J.P.C. de Weerd Evoked potentials are the electrical voltage fluctuations which can be recorded from parts of the nervous system in response to stimulation of sensory modalities. (springer.com)
  • As with any evoked-potential test involving unilateral stimulation, excessive symmetries between the measurements following left-sided stimulation and those following right-sided stimulation also may reveal abnormalities. (medscape.com)

  • Somatosensory evoked potentials following median nerve stimulation. (medscape.com)
  • Evoked potential monitoring is performed at the probe surface via stimulation energy delivered along the electrical pathway, and tissue/bone resection occurs with rotation of the cutting tip. (google.es)
  • Sensory evoked potentials studies measure electrical activity in the brain in response to stimulation of sight, sound, or touch. (nhrmc.org)
  • How reproducible are transcranial magnetic stimulation induced Motor Evoked Potentials in subacute stroke? (biomedsearch.com)
  • Motor evoked potentials (MEPs) and total motor conduction time (TMCT) induced by transcranial magnetic stimulation (TMS) are used to make assumptions about the prognosis of motor outcome after stroke. (biomedsearch.com)
  • Assessing the reproducibility of transcranial magnetic stimulation (TMS) measurements requires studies to investigate the test-retest reliability of TMS induced motor evoked potentials (MEPs) and total motor conduction time (TMCT). (biomedsearch.com)
  • mfVEPs
  • In order to assess the influence of optical factors on the multifocal visual evoked potential (mfVEP), we obtained mfVEPs with optimal refraction and compared them to recordings with various degrees of dioptrical defocus. (springer.com)
  • SSEP
  • Since a SSEP can be completely described in terms of the amplitude and phase of each frequency component it can be quantified more unequivocally than an averaged transient evoked potential. (wikipedia.org)
  • methods
  • This being the case, there is need for the EEG technician to become familiar with evoked-potential methods and to add a variety of new skills to his or her repertoire. (springer.com)
  • amplitude
  • 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. (wikipedia.org)
  • objective
  • Therefore, the objective of this study was to characterize the results of LLAEP obtained in children with phonological disorder and to investigate the development of the potential after Speech therapy as well as to correlate the development of potentials and the history of otitis and severity of the phonological disorder.
