Reliability analysis of event-related brain potentials to olfactory stimuli.
Olfactory event-related potentials (OERP) have been used to investigate olfactory processing in health and disease. However, the reliability of the OERP has yet to be established statistically. The present study examined test-retest reliability of the OERP over a 4-week interval. EEG was recorded from Fz, Cz, and Pz, using a single-stimulus paradigm with amyl acetate. Reliabilities for ERP comp...
متن کاملVisual event-related potentials to moving stimuli: normative data.
Visual cognitive responses (P300) to moving stimuli were tested in 36 subjects with the aim to find the normal range of P300 parameters. Concomitantly, the circadian intra-individual variability of the P300 was studied in a subgroup of 6 subjects. Visual stimuli consisted of either coherent (frequent stimulus) or non-coherent motion (random stimulus). The oddball paradigm was applied for record...
متن کاملEvent-related potentials to emotional stimuli in migrainous children.
The present preliminary study was aimed at investigating the electrocortical correlates of attentional allocation toward emotional stimuli in children and adolescents with migraine by means of the event-related potentials. The electroencephalogram was continuously recorded in 7 migrainous children and 8 healthy controls while they were looking at a series of pleasant, neutral, and unpleasant pi...
متن کاملHuman event-related brain potentials to auditory periodic noise stimuli.
Periodic noise is perceived as different from ordinary non-repeating noise due to the involvement of echoic memory. Since this stimulus does not contain simple physical cues (such as onsets or spectral shape) that might obscure sensory memory interpretations, it is a valuable tool to study sensory memory functions. We demonstrated for the first time that the processing of periodic noise can be ...
متن کاملEvent-related potentials to emotional and neutral stimuli in alcoholism.
Several studies have demonstrated that the emotional value of stimuli affects P300 amplitude. In the present study, the influence of alcohol-related stimuli in alcoholic patients was investigated. Subjects were 10 alcoholic inpatients (3 female) and 10 age- and sex-matched controls. Eight alcohol-related and 8 neutral words served as stimuli in a visual oddball paradigm. Acohol-related words we...
