Välkomna till det andra seminariet i fonetik i den serie som under denna termin fokuserar på hur människans hjärna representerar och tolkar sensorisk information samt på metodologiska och filosofiska frågor med anledning av neurologiska studier.

Tid: onsdag 9 oktober kl. 15:00-17:00
Plats: rum C397, Södra huset, Frescati

Postseminarium äger rum direkt efter seminariet i institutionens pentry.


Oscillations constitute an inextricable aspect of neural dynamics. Although a considerable body of evidence revealing their strong correlation with various cognitive processes has been assembled, yet our understanding of the origins and mechanisms underlying these correlations is limited. We adopt a computational approach to address these questions. To this end, we devise mesoscale network models that lend themselves to examining oscillatory phenomena as an emergent feature of neuronal activity and as a correlate of the network's functional states. In this regard, we consider an attractor theory of brain computations as a plausible framework for modelling cortical memory or perception function.

In this talk I am going to briefly outline current perspectives on neural oscillations as a correlate of brain function. Then I will present our recent work on large-scale biologically detailed attractor network models that produce oscillatory dynamics in a wide band ranging from theta to gamma and discuss how our findings relate to a growing body of experimental data with emphasis on neuroimaging studies relying on electroencephalography (EEG) and magnetoencephalography (MEG). Finally, I will discuss the relevance of studying brain oscillations in cognitive neuroscience of language or, broadly speaking, linguistics and suggest how computational approach can assist in this endeavour.
