“…Stimulus repetition leads to task learning and a reduction in neural activity and this has been associated to improved task performance (Grill-Spector et al, 2006). Since the frequency and timing of the auditory oddball were the same in the two sets, the amount of new information was reduced in the third compared to the second set, likely leading to the participants becoming habituated to the task (Ritter et al, 1968). This may have allowed them to maintain their focus within the third set of dorsiflexion.…”

Objective: In this study, we analyzed the influence of artificially imposed attention variations using the auditory oddball paradigm on the cortical activity associated to motor preparation/execution.Methods: EEG signals from Cz and its surrounding channels were recorded during three sets of ankle dorsiflexion movements. Each set was interspersed with either a complex or a simple auditory oddball task for healthy participants and a complex auditory oddball task for stroke patients. Results:The amplitude of the movement-related cortical potentials (MRCPs) decreased with the complex oddball paradigm, while MRCP variability increased. Both oddball paradigms increased the detection latency significantly (p<0.05) and the complex paradigm decreased the true positive rate (TPR) (p = 0.04).In patients, the negativity of the MRCP decreased while pre-phase variability increased, and the detection latency and accuracy deteriorated with attention diversion. Conclusion:Attention diversion has a significant influence on MRCP features and detection parameters, although these changes were counteracted by the application of the laplacian method.Significance: Brain-computer interfaces for neuromodulation that use the MRCP as the control signal are robust to changes in attention. However, attention must be monitored since it plays a key role in plasticity induction. Here we demonstrate that this can be achieved using the single channel Cz.

“…This finding is unequivocal when the infrequent stimulus is made "task relevant" by the experimenter; that is, if the subject must actively differentiate the infrequent stimulus from the others and acknowledge this selection with an overt or covert response. On occasion, stimuli having no assigned task relevance, presented infrequently, also have been demonstrated to generate P3 waves larger than to the frequent stimuli (Ritter, Vaughan, & Costa, 1968;Roth, 1973;Courchesne, Hillyard, & Galambos, 1975;Squires, Squires, & Hillyard, 1975;Roth, Ford, Lewis & Kopell, 1976;Snyder & Hillyard, 1976;Courchesne, Courchesne & Hillyard, 1977;Squires, Donchin, Herning, & McCarthy, 1977). These effects, however, are characterized by variability in the P3 waveform and amplitude and are considered controversial.…”

Event-related potentials (ERPs) were recorded from subjects as they silently read 160 different seven-word sentences, presented one word at a time. Each sentence was in itself a natural, meaningful phrase. Substantial intersubject variability was observed in the ERP waveshapes following the words. More than half of the subjects generated P3 components to word stimuli, but those who did showed similar responses to repeated control presentations of a single word. In addition, it was found that all but the first word in the sentence elicited an ERP with a significant left-greater-than-right asymmetry in the late positivity over temporo-parietal regions. The ERPs to the last words were associated with more late positivity than those to the preceding words. One quarter of the sentences, at random, ended with a word printed in a typeface that was different from that of the preceding words. This infrequent change in typeface elicited a complex ERP having three consistent late positive components.

“…However, some results in the passive paradigm showed that P3-like ERPs tended to habituate across sessions (Paller, 1986), whereas in other cases P3-like ERPs were never found (Glover et aI., 1986). Similarly, passive conditions have led to variable results in human subjects (Donchin and Cohen, 1967;Ford, Roth, and Kopell, 1976;Polich, 1989b;Ritter, Vaughan, and Costa, 1968;Roth et aI., 1976;Smith et aI., 1970;Squires et aI., 1977). The reliability ofP3 may depend on the extent to which attentional resources are devoted to processing the stimuli.…”

“…Stimuli from a relatively infrequent class ("oddball" stimuli) reliably elicit P3 if the subject actively discriminates the stimuli, for example, by counting stimuli from one class. In some cases, P3 can be elicited by oddball stimuli not given explicit relevance (Ritter, Vaughan, and Costa, 1968;Roth et aI., 1976;Squires et aI., 1977), but often the scalp topography then has a frontal maximum and the peak latency is shorter (e.g., Squires, Squires, and Hillyard, 1975). P3 amplitude tends to decrease when attention is diverted (Wickens et aI., 1983), or when the subject is uncertain about having correctly perceived the stimulus (Hillyard et aI., 1971;Ruchkin and Sutton, 1978).…”

O~e reaso.n to study the electrical activity of the brain is that the knowledge game.d might be useful for understanding the neural basis of cognitive functlOns. I~other words, endogenous or cognitive event-related potentials (~RPs), which are. averaged field potentials that are sensitive to manipulahons of psychological variables, could provide evidence to constrain theories on the brain mechanisms that mediate cognition. The success of this approach, however, depends on the extent to which two types of relationships can be s~bsta~tiated: relationships between ERPs and theories of cognition and relatlOnshlps between ERPs and particular neural events, structures, or ystems. Alth~~gh cognitive ERPs have been thoroughly characterized only m humans, cnhcal evidence for clarifying the neurophysiological substrates of cognitive ERPs may come from studies in animals (Galambos and Hillyard, 1981~. This review focuses on recent studies that have begun to develop ammal models of a particularly well-characterized cognitive E~P, the P3 or P300 potential. To develop criteria for assessing these ammal models, the characteristics of P3 in humans are first outlined. Evidence pertaining to the adequacy of each of the putative animal models is then discussed by species, along with evidence about the neural basis of th:se ERPs. The concluding section will reflect on prospects for understandmg the neural basis of P3 and on the usefulness of the animal approach..Cognitive Electrophysiology
