Cognitive processes and brain-machine interfaces
A substantial part of research on brain-machine interfaces (BMIs) focuses on using cerebral electrophysiological correlates of motor activity to operate devices. However, brain correlates of cognitive processes can also be exploited in order to enhance human-machine interaction. For instance, invasive and non-invasive BMIs have explored correlates of error awareness to correct misclassification or as a teaching signal to improve performance; complementary research on invasively recorded reward-related activity has also been undertaken. Other approaches attempt to decode neural activity related to attentional and anticipatory processes, as well as sensory processing and mental workload.
Conversely, BMIs can also provide valuable information to better understand the neurophysiology of such cognitive processes. In particular they allow to study these processes in interactive environments, as opposed to the traditionally used experimental paradigms. Recent work has shown how BMI paradigms can be used to study subjective senses of limb ownership and agency – a seemingly crucial aspect for efficient motor neuroprosthetics.
This workshop will present some of the most exciting research done recently in this regard, paving the way for discussing the major challenges in the field.
- Put yourself in the spotlight!! We’ll allocate time for selected presenters to briefly expose their ideas (2min, one slide). Thought-provoking, controversioal points are more than welcome. If you’re intersted write us an email.

Deadline for abstract submission: 31 Aug 2013
The workshop is aimed at both novice and experienced researchers on BMI, as well as researchers in cognitive neuroscience and psychology.
Each participant will be asked to provide a short description (1 slide) about his/her research and up to 3 major points he/she wants to see addressed in this workshop beforehand. Selected contributions will be presented during the workshop as spotlights to trigger targeted discussion among participants.
