Recording and low-level processing of electrical brain activity

Recording the brain activity is the first link in the processing chain of a brain-computer interface. For various reasons, both technological and physiological, this stage is probably the most critical despite the progress made in recent years. Although it is possible to measure other indices of cerebral activity, it is mainly the brain electrical activity that continues to attract the interest of teams developing BCIs. In this talk, I will present several different approaches to recording, on the one hand, and to low-level processing, on the other hand, brain electrical activity. The aim of these techniques is to highlight markers of specific brain states that can serve as a basis for the implementation of a BCI.
