High impact information on Evoked Potentials

  • Significantly lower doses of deferoxamine were being taken by patients without abnormalities than by those with visual symptoms, abnormal audiograms, or prolonged evoked potentials (P less than 0.001, less than 0.006, and less than 0.04, respectively) [11].
  • Task-relevant late positive component of the auditory event-related potential in monkeys resembles P300 in humans [12].
  • Work on brain event-related potentials (ERPs) suggests that people with high IQ test scores: (1) show faster responses in some test conditions; (2) have ERP waveforms that can be distinguished from those of people with lower IQs; and (3) might have less variability in their ERPs [13].
  • To better understand the triggering elements of visual stimuli and cortical mechanisms of hyperexcitability, we examined eleven patients with idiopathic photosensitive epilepsy by recording visually evoked potentials (VEPs) in response to temporally modulated patterns of different contrast [14].
  • This caused marked potentiations of both quantal and action potential-evoked EPSCs mediated by alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) or N-methyl-D-aspartate (NMDA) receptors [15].

Associations of Evoked Potentials with chemical compounds

  • In contrast, DALA reduces the amplitude of action potential-evoked, GABA-mediated IPSCs, as well as decreases their frequency [31].
  • Within 30 min of contact, action potential-evoked calcium accumulation was reversibly augmented from 228 +/- 82 nM to 803 +/- 212 nM, an action that was blocked by H-7 (40-100 microM) [32].
  • Cognitive function (latency of P300 evoked potentials) deteriorated to the same extent in both studies at this glucose level [33].
  • Similarly, thiocyanate and perchlorate were the only chaotropic ions tested that increased the initial slope and amplitude of the extracellularly recorded potentials evoked in CA1 dendritic field [34].
  • The pharmacological properties of action potential-evoked NE release paralleled those of N-type Ca2+ channels: Release was completely blocked by Cd2+ or omega-conotoxin GVIA, reduced 50% by 10 microM NE or 62% by 2 microM UK-14,304, an alpha2-adrenergic agonist, and reduced 63% by 10 microM oxotremorine M (Oxo-M), a muscarinic agonist [35].

Gene context of Evoked Potentials


Analytical, diagnostic and therapeutic context of Evoked Potentials

  • Averaged event-related potential (ERP) data recorded from the human scalp reveal electroencephalographic (EEG) activity that is reliably time-locked and phase-locked to experimental events [41].
  • Here, we propose a simple and robust way to integrate functional MRI (fMRI) with single trial event-related potentials (ERP) to provide a more complete spatiotemporal characterization of evoked responses in the human brain [42].
  • Functional neuroimaging studies have implicated the fusiform gyri (FG) in structural encoding of faces, while event-related potential (ERP) and magnetoencephalography studies have shown that such encoding occurs approximately 170 ms poststimulus [43].
  • Some of these waveforms were derived from barrages of postsynaptic potentials evoked by visual stimulation recorded in vivo; others were artificially created and contained various amounts of gamma range fluctuations; finally, others consisted of swept-sinewave current (ZAP current) functions [44].
  • After injury, the spinal cord evoked potentials showed greater recovery of both amplitude and latency in the vitamin E-supplemented group than in the control group [45].
