Connectivity analysis based on EEG recordings: from motor tasks to the human social brain
Tuesday, 26 June, 2018 - 09:00
Laura Astolfi, Ricercatrice a Tempo Determinato di tipo B (SSD ING-INF/06), terrà un seminario sulle attività di ricerca svolte e in corso di svolgimento, in vista della delibera con cui il Consiglio di Dipartimento si esprimerà sulla sua chiamata nel ruolo di Professore di II fascia, a seguito dell’esito positivo ottenuto nella procedura valutativa della sua attività di ricerca e didattica.
Il seminario precederà il Consiglio di martedì 26 giugno nell'aula magna del Dipartimento, e avrà inizio alle ore 9:00.
Understanding the brain organization that underlies human complex functions is a central problem both in basic research and for clinical applications. The description of brain circuits established during specific tasks (or at rest) can provide important insights into the neural mechanisms at the basis of motor and cognitive functions, their reorganization resulting from different pathological conditions and their recovery, whether spontaneous or due to a specific treatment (brain plasticity). Electroencephalography (EEG) is a non-invasive, low-cost, portable technique for the investigation of brain activity that provides the time resolution (milliseconds) necessary to follow the brain dynamics and to perform an effective estimation of brain functional connectivity. In this seminar, the methods at the basis of the estimation of brain connectivity in the time, frequency and time-frequency domains will be introduced, together with the most recent advancements in this field. The lecture will discuss the advantages of performing the analysis in the EEG source space, and how a graph theory approach can be adopted to summarize and quantify brain networks properties. The importance and role of the statistical assessment of connectivity patterns will be also illustrated. Finally, some applications will be shown, ranging from the study of cortical reorganization following motor or cognitive rehabilitation to the description of social cognitive functions (empathy, cooperation, individualistic behavior). To this last purpose, the novel technique of Hyperscanning, or simultaneous multi-subject EEG recordings, will be introduced. In conclusion, future directions of these studies and possible interactions with other fields of research will be critically discussed.
