Nearly 100 years after the first electroencephalography (EEG) recordings, brain wave analysis remains a central focus in psychology and neuroscience research and is widely used in clinical diagnostics and rehabilitation.
Within the context of a collaboration between the Psychophysics and Neural Dynamics Lab (UNIL/CHUV/theSense) and the Neuromove-rehab Lab (UNIPD), “Rhythms of the Brain: Integrating Knowledge from Perception and Sensory-Motor Research”, funded by the strategic partnership between UNIL & UNIPD and the Sense, we are hosting a symposium to address state-of-the-art methodological and theoretical issues in the study of brain waves. This symposium is dedicated to highlighting the contributions of early career researchers.
(CerCo, CNRS)
Andrea will present a predictive coding model of alpha rhythms (8-13 Hz), showing how predictive mechanisms in the visual cortex may generate alpha-band traveling waves, and how these mechanisms might differ in psychedelic states and schizophrenia.
(UNIGE)
Isotta will present a novel EEG network analyses approach in epilepsy, using graph signal processing to integrate structural and functional connectivity for clinical biomarkers.
(University of Padova)
Edoardo will discuss sensorimotor adaptation, focusing on how visual and proprioceptive information integration supports posture maintenance. He will present findings from behavioral and EEG studies, highlighting alpha-band oscillations as biomarkers of postural demand and adaptability.
(Charité – Universitätsmedizin Berlin)
Dario will assess EEG features as potential endophenotypes in schizophrenia. His study of a large cohort of patients and controls reveals surprisingly low correlations among EEG features, even among those typically associated with the disorder. This suggests that different EEG features may capture distinct and highly heterogeneous aspects of the disease rather than a unified characteristic.
(EPFL)
Melissa will illustrate the high inter-individual variability and high intra-individual stability of subject-level event-related potential (ERP) waveforms using results from a 10 year long longitudinal study. These results question the validity of group-level ERP and raise the question of the meaning of individual differences in ERP.
(UNIL/CHUV/TheSense)
Maëlan will discuss the role of alpha oscillations in perception, using EEG recordings during tasks that involve the long-lasting integration of visual stimuli. His findings suggest that alpha oscillations affect visual processing beyond the temporal resolution of a single alpha cycle, contributing to the ongoing efforts to understand the functions of alpha rhythms in perception.
(UC Berkeley)
Mattia will investigate the role of alpha oscillations in working memory (WM), particularly within the frontal-parietal network. His neuroimaging and TMS studies demonstrate the dual function of alpha activity in suppressing irrelevant information and maintaining WM through phase-coding mechanisms.
(UCLA)
Martin will present his results on theta (3-9 Hz) dynamics during real and imagined navigation using intracranial EEG in freely moving individuals. His results suggest that theta oscillations encode spatial and temporal transitions, with EEG source imaging revealing functional connectivity between the medial temporal lobe and prefrontal cortex.
Time: December 11, 2024
