difference ( Nd ) event - related potential
Frontal and temporal lobe sources for electrical activity associated with auditory controlled attention (negative difference, Nd) were sought for comparison with those reported to arise from the earlier detection of stimulus-change (mismatch negativity, MMN: Jemel et al. 2002). In two sessions a month apart (T1 and T2), 14 subjects were presented with a 3-tone oddball passively, then as a discr...
متن کاملHz Event Related Auditory Potential
Main focus of this paper is an EEG experiment on observing frequency of event related auditory potential in response to series of clicks. Based on the past research, it was expected to observe 40 Hz potential, which was not the case. The experiment was conducted on one subject, and the average observed frequency of 61 Hz could be explained by individual differences. However, an additional step ...
متن کاملNeural correlates of size illusions: an event-related potential study.
The aim of this study was to investigate the neural correlates of size illusions. Participants were presented with a sphere of a fixed angular size positioned (i) at either a far or close position within a three-dimensional virtual scene or (ii) at either an upper or lower screen position on a plain gray background. The visual-evoked potentials were recorded while participants were required to ...
متن کاملSyntactic processing with aging: an event-related potential study.
To assess age-related changes in simple syntactic processing with normal aging, event-related brain potentials (ERPs) elicited by grammatical number violations as individuals read sentences for comprehension were analyzed. Violations were found to elicit a P600 of equal amplitude and latency regardless of an individual's age. Instead, advancing age was associated with a change in the scalp dist...
متن کاملThe Attention Modulation on Timing: An Event-Related Potential Study
The present study examined the neural mechanisms of attention modulation on timing using ERP and sLORETA measurements in a dual-task paradigm. We parametrically varied the attention to the durations of a 1000-Hz pure tone and further localized the cortical regions that were sensitive to the attention modulation on timing. Results demonstrated that the attention modulation might happen at early ...
