Event-related potentials in schizophrenics
Electroencephalography and Clinical Neurophysiology, 1980Fifteen schizophrenics and 15 age-matched controls were compared on 3 auditory event-related potential (ERP) paradigms that elicited a variety of components. In one paradigm, tones were given at 0.75, 2.25 and 6.75 sec interstimulus intervals; in another, infrequently occurring targets in a reaction-time task were interspersed with frequent background ...

Event-Related Potentials in Hypertriglyceridemia
International Journal of Neuroscience, 1995Event-related potentials (ERPs) of twenty-three hypertriglyceridemic (HTG) patients and twenty-three age-matched healthy controls were recorded in two different experimental conditions that the target stimulus was counted (Test 1) or uncounted (Test 2). Latencies of each wave were inside normal limits in all patients.

Detection of Event Related Potentials
International Journal of Neuroscience, 1989A statistical approach is presented which provides efficient procedures to detect both Event Related Potential (ERP) and its spectral structure. Situations where undesirable signal or "artifact" is present, are considered. In these cases, a "noise" sample can be used which complements the insufficient knowledge given for the sample where we expect to ...

Event-Related Potentials in Psychiatry
Clinical EEG and Neuroscience, 2007Electrophysiological assessments of psychiatric disorders have produced a number of promising, highly replicable findings and thus carry the potential of becoming clinically utilizable in the diagnostic or prognostic evaluation of psychopathological conditions.

A `passive' event-related potential?
International Journal of Psychophysiology, 1998Event potentials (ERPs) were recorded in response to visual patterns in two conditions: (1) where no instructions were given to subjects; and (2) where subjects pressed a button whenever a rare stimulus was detected. P3 amplitudes for the No Instructions condition were smaller than for the Active condition, but the latency of the P3s did not differ ...

In most event-related potential (ERP) studies, the averaging technique is used twice for ERP extraction. First, the trials are averaged separately for each experimental condition and for each participant. We can call this procedure average within subject; through this step, we get the averaged file.

Event related potentials in hypothyroidism.
Electromyography and clinical neurophysiology, 2008Central nervous system (CNS) dysfunction is an important consequence of thyroid hormone deficiency Several studies using objective behavioral measures reported that cognition is impaired in patients with hypothyroidism. The aim of the present study is to evaluate objectively the functional changes in the nervous system and possible cognitive effects of

Movement-Related Potentials and Event-Related Potentials
2016Movement-related cortical potentials (MRCPs) are EEG potentials that occur with movement and are recorded using surface scalp electrodes. A technique termed “EEG-EMG back-averaging” is used to obtain MRCPs. The earliest recordable MRCP is the Bereitschaftspotential or readiness potential.

Abstract From a historical perspective, the realization that schizophrenia is a brain disorder has been fairly recent (Kraepelin, 1899); even more recent has been the development of the tools and methodologies that have allowed investigations into the nature of brain dysfunction in schizophrenia.

Event-related potentials (ERPs) can be elicited by a variety of stimuli and events in diverse conditions. This chapter covers the methodology of analyzing and quantifying ERPs in general. Basic models (additive, phase modulation and resetting, potential asymmetry) that account for the generation of ERPs are discussed. The principles and requirements of
