<p class="MsoNormal"><span style="font-size:11.0pt">Summary: Brain activity consists of periodic and aperiodic signal elements which evolve actively in relation to ongoing behaviours. This presentation introduces the concepts and methods for decomposing and
parameterizing neural dynamics into periodic and aperiodic components in a time-resolved manner. Using these methods, we demonstrate aperiodic dynamics in resting-state human magnetoencephalography, as well as in rodent electrophysiology coinciding with task-based
behaviours.</span><span style="font-size:10.0pt"><o:p></o:p></span></p>

<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;color:blue"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Dynamic functional connectivity (dFC) has become an important measure for understanding brain function and as a potential biomarker . However , various methodologies have been developed for assessing dFC,
and it is unclear how the choice of method affects the results. In this work, we aimed to study the variability of commonly used dFC methods. We applied 7 dFC assessment methods to analyze the functional magnetic resonance imaging data of 395 subjects from
the Human Connectome Project. We measured the similarity of dFC results yielded by different methods using several metrics to quantify overall, temporal, spatial, and intersubject similarity. We show a range of weak to strong similarity between the results
of different methods, indicating considerable overall variability. Somewhat surprisingly, the observed variability in dFC estimates was found to be comparable to the expected functional connectivity variation over time, emphasizing the impact of methodological
choices on the final results. Overall, our findings shed light on the impact of dFC assessment analytical flexibility and highlight the need for multi-analysis approaches and careful method selection to capture the full range of dFC variation.
