"Human electrical brain activity: non-invasives mesures" Maureen Clerc (Slides)
Mini-course
Brain is the source of permanent electric activity resulting from communication between neurons. By measuring this activity, one can gets access to its spatio-temporal dynamics, by determining which brain region is involved in a given task [...]
In this talk, we focus on the non-invasive measurement of electroencephalography (EEG) and magnetoencephalography (MEG). The sensors on these instruments are outside the head, and have a result, a remote view of the activity. We explain the distortions that result, as well as the processings to extract the maximum of information from these measurements. These processings are obtained by solving so-called "inverse" problems of recontruction or separation of sources. Maximizing the amount available information is an essential step to better interpret experimental measurements, whether in clinical or cognitive science.
