Get To Be The First To Read What The Masters Are Saying Over B3GAT3

Again, as in the single-task Experiment 1, differences in amplitude between acceptable and unacceptable target nouns were evident in the N400 time window. Figure 3. Event-related potentials from the Dual Task Experiment 2, referred to a 100 ms prestimulus baseline. Panel A depicts ERP wave shapes at the Fz, Cz and Pz electrode in response to acceptable and unacceptable target words at each SOA. Panel B superimposes ... Difference waves of the grand averages are depicted in Figure 3B, superimposed for the three SOA conditions at the Pz electrode. The amplitudes of these difference waves between 400 and 600 ms seem to be modulated by SOA, being smallest at SOA 100. Figure 3C depicts the scalp topography of the N400 component (time window 400-600 ms), which again is a widely B3GAT3 distributed negativity along the midline and at centro-parietal electrodes. The patterns we observed in this experiment for the acceptability effects were long-duration difference AUY-922 cell line waves. Consequently, it was not feasible to measure peak latencies or peak amplitudes. Instead, the quantitative analysis was restricted to average amplitude measures between 400 and 600 ms. As can be seen in Table 1 there was a significant effect of acceptability between 400 and 600 ms, which significantly interacted with the factors SOA and Electrode. In a further step the factor Acceptability was analyzed within each SOA. At SOA 100 it failed significance, F(1, 19) = .49, p > .05, but at SOA 400 and 700 this factor was significant (SOA 400: F = 4.86, p Cp3, Cp4, P3, Pz, P4, O1 and O2) was run. This yielded significant main effects of SOA, F(2, 38) = 4.9, p = .016, and acceptability, F(1, 19) = 21.35, p = .000, as well as a strong trend for an interaction www.selleckchem.com/products/sch-900776.html between these factors, F(2, 38) = 3.1, p = .057. Tests at single electrodes (Cz or Pz only) did not yield significant results, possibly because of the wide distribution of the N400. Differences in amplitude between acceptable and unacceptable target nouns were again evident in the P600 time windows. This time, the P600 seemed to be affected by SOA, with a reduction in amplitude (particularly at short SOA) already in an earlier time window (between 850 and 950 ms, cf. Table 1) as compared to Experiment 1. However, there was only a trend for an interaction with SOA (p = .09). Excluding the factor electrode and running analyses only for the Pz electrode, where this component was largest, this interaction was significant, F(2, 38) = 3.96, p
