The Centre for Cognitive Neuroscience at UGent (CCN) is happy to announce its second special lecture in the series of Van Biervliet lectures

Professor Ole Jensen (Birmingham University, UK) will talk about the role of alpha an gamma activity in information processing.

On the role of alpha and gamma activity for routing and prioritizing information processing

 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.



Jules Van Biervliet (1859-1945) was the first psychologist at Ghent University. He came from a family of well know medical doctors. Jules was a doctor in arts and philosophy, candidate in medicine and doctor in physical sciences. In 1890, he was a professor in metaphysics and psychology at Ghent University. A year later, he founded a laboratory for Experimental Psychology at Ghent University, the first in Belgium and one of the first in Europe. To prepare for this, he went for training to the laboratory of Wilhelm Wundt in Leipzig, of which he wrote an interesting account. He also inspired Binet in the development of the first intelligence test, as can be read here.
