In the form of a pie chart, Figure 4 plots the distribution of synchrony (≤20% error, that is inside the box in Figure 3), dyssynchrony (>20% error, that is outside the box in Figure 3), and asynchronies for each mode.
The errors in synchrony with respect to the N100 and P200 components were less than 1 ms and −11 ms for subjects 1 and 2, respectively.
One might speculate, that during joint actions, the cerebellum may play a similar integrative role in detecting errors in synchrony between ones own actions and those of others.
computes the difference between the first and second columns, that is, the error in synchrony.
The two main plots show for subjects 1 and 2 (upper and bottom plots, respectively) the TAP-S-based trial averaging of the target ERPs taken as the error of synchrony as shown from the values of Table 2 (thick lines).
The authors have used a sophisticated automatic algorithm to define acceptable synchrony (that is, an error between electrical activity of the diaphragm and airway pressure above 20%) [ 1].
Interestingly, in EEG, we have also shown that unconscious errors triggered increased oscillatory phase synchrony between prefrontal and visual electrodes leading up to the next trial.
In this case, error-correction serves as a synchrony finder with free parameter k, similar to how "K-means" is a standard unsupervised approach to decompose data into K clusters.
First, type II error in the detection of synchrony was increased (failure to detect synchrony when it occurs).
Although improved by increasing PEEPe, the NeuroSync index was at least three times higher (worse patient-ventilator interaction) during PSP mainly due to dys-synchrony i.e., trigger and cycling-off errors, which cannot be determined with pressure-flow-volume waveform analysis without EAdi [ 11, 18].
