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.

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

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.

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 ...

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 ...

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 ...

Warp-averaging event-related potentials
Clinical Neurophysiology, 2001To align the repeated single trials of the event-related potential (ERP) in order to get an improved estimate of the ERP.A new implementation of the dynamic time warping is applied to compute a warp-average of the single trials. The trilinear modeling method is applied to filter the single trials prior to alignment.

Olfactory (Chemosensory) Event-Related Potentials
Toxicology and Industrial Health, 1994Chemosensory event-related potentials (CSERPs) have found their way into a number offields of research where they help to determine the function of both the trigeminal and the olfactory system. The investigation of chemosensory deficits in patients with Parkinson's or Alzheimer's disease is only one of the typical applications.
