[BIC-announce] MNI Killam Lecture - Ole Jensen - Tuesday, November 8, 2016

[Sylvain Baillet, Dr]

Dar all:


Highly-recommended - Ole Jensen's Killam lecture next week: of great interest to all who want to learn more about the functional role and relevance of neural oscillations, and how they can be captured and modulated with MEG.


Best wishes,


Sylvain.

Title:  On the Role of Alpha and Gamma Activity for Routing and Prioritizing Information Processing

Date:  Tuesday, November 8, 2016

Time:  4pm

Place:  de Grandpré Communications Centre

-----------------------------------------------------------

Networks in the brain must rely on powerful mechanism for routing and prioritizing information processing. In a larger set of attention and memory studies we have investigated the notion that alpha oscillations (9 - 12 Hz) are inhibitory and serve to route the information flow: 'gating by inhibition'.  The alpha band activity is under top-down control by areas in the dorsal attention network. As such the alpha band activity - previously believed to reflect a state of rest - serves an important role for shaping the functional architecture of the working brain. Gamma band activity (50 - 100 Hz) reflects feed-forward processing and is modulated by the alpha oscillations. Importantly, the gamma activity is coupled to the phase of the alpha oscillations. We have found support for this framework using MEG, DTI/MEG, TMS/MEG, fMRI/EEG and non-human primate data. In future work we will investigate how alpha oscillations provide a mechanism for prioritizing sensory information processing by means of phase-encoded representations.
