DESCRIPTION:Jason da Silva Castanheira presents\, 'MEG Myself & I: Brief se
 gments of neurophysiological activity enable individual differentiation'. 
 \n\nRegistration available here.\n\nSpeaker: Jason da Silva Castanheira\, 
 PhD Student\n\nMontreal Neurological Institute\, 91µ¼º½ÊÓƵ\, Montr
 eal\, QC\, Canada\n\nAbstract: Large\, openly available datasets and curre
 nt analytic tools promise the emergence of population neuroscience. The co
 nsiderable diversity in personality traits and behaviour between individua
 ls is reflected in the statistical variability of neural data collected in
  such repositories. Recent studies with functional magnetic resonance imag
 ing (fMRI) have concluded that patterns of resting-state functional connec
 tivity can both successfully distinguish individual participants within a 
 cohort and predict some individual traits\, yielding the notion of an indi
 vidual’s neural fingerprint. Here\, we aim to clarify the neurophysiologic
 al foundations of individual differentiation from features of the rich and
  complex dynamics of resting-state brain activity using magnetoencephalogr
 aphy (MEG) in 158 participants. We show that akin to fMRI approaches\, neu
 rophysiological functional connectomes enable the differentiation of indiv
 iduals\, with rates similar to those seen with fMRI. We also show that ind
 ividual differentiation is equally successful from simpler measures of the
  spatial distribution of neurophysiological spectral signal power. Our dat
 a further indicate that differentiation can be achieved from brain recordi
 ngs as short as 30 seconds\, and that it is robust over time: the neural f
 ingerprint is present in recordings performed weeks after their baseline r
 eference data was collected. This work\, thus\, extends the notion of a ne
 ural or brain fingerprint to fast and large-scale resting-state electrophy
 siological dynamics.\n\nBio: Jason da Silva Castanheira is a PhD student a
 t the IPN in Dr. Sylvain Baillet's lab. He studies individual differences 
 in neural activity\, our so called 'neural fingerprint'\, as well as the c
 ognitive neuroscience of attention.\n\n\nThe Feindel Virtual Brain and Min
 d (VBM) Seminar Series will advance the vision of Dr. William Feindel (191
 8–2014)\, Former Director of the Neuro (1972–1984)\, to constantly bridge 
 the clinical and research realms. The talks will highlight the latest adva
 nces and discoveries in neuropsychology\, cognitive neuroscience\, and neu
 roimaging.\n\nSpeakers will include scientists from across The Neuro\, as 
 well as colleagues and collaborators locally and from around the world. Th
 e series is intended to provide a virtual forum for scientists and trainee
 s to continue to foster interdisciplinary exchanges on the mechanisms\, di
 agnosis and treatment of brain and cognitive disorders.\n
