Modulation of Cortical Excitability by Detection of Motor Intention and Artificial Afferent Feedback

Modulation of Cortical Excitability by Detection of Motor Intention and Artificial Afferent Feedback

This video was recorded at BBCI Workshop: Advances in Neurotechnologies, Berlin 2012. Brain-computer interfaces (BCI) have applications in function restoration, function replacement, and communication. A further potential application of BCI systems, which has been less extensively investigated, is their use for promoting plastic changes during the recovery of motor and/or sensory functions (neuromodulation). In this talk, I will focus on methods that have been developed to change the cortical excitability in humans by associating motor commands and artificial afferent volley (e.g., electrical stimulation) delivered with precise temporal delay. In such systems, the online detection of cortical activation associated to movement imagination (motor evoked cortical potential, MRCP) is equivalent... Show More
