Event-related brain potentials (ERPs), such as Nd and P300, change as a function of the proportion of time if a rare, significant, stimulus occurs. This 'oddball' paradigm has had a significant influence on the interpretation of ERPs in terms of the psychological and information-processing functions they reflect. Interpretations of transient components have(More)
Migraine patients are thought to show some cognitive dysfunction and slight structural abnormalities in the white matter of the brain, whereas most patients with multiple sclerosis (MS) are known to have numerous white matter lesions, often affecting the corpus callosum. To demonstrate psychomotor dysfunction, an alternate finger tapping task (a-FTT) on a(More)
In previous studies we found an inverse relationship between CNV amplitude and the probability of the occurrence of the warning stimulus (S1) in a cued reaction time task. The aim of the present study was to investigate this 'oddball effect' on CNV amplitude (Oddball CNV) in patients with anxiety disorders, since this effect describes the influence of event(More)
Two female rhesus monkeys with cortical and subcortical DC-electrodes were studied during self-paced operant responding to determine the feasibility of mapping the intracerebral distribution of readiness potentials (RP). These potentials reflect preparatory aspects of motor activation and may be useful indicators of subcortical areas involved in preparatory(More)
