On being challenged adequately by a restorative BCI

The utility of a restorative BCI depends not only on machine learning measures like classification accuracy, but also on how the subject experiences the intervention. Roughly a quarter of subjects appear to suffer from BCI-illiteracy, i.e. they have difficulty when trying to control a BCI. An interesting question is whether they differ in their experience… Read more »

On exploiting the cue from cue-paced, synchronous BCIs

Many BCIs are cue-paced, i.e. they signal the start and end of the control phase to the user. Because this gives the BCI a task-like structure, such a synchronous approach is not very useful for assistive applications. Yet, there are several benefits of such a task-structure, which makes this approach very applicable for restorative BCIs… Read more »

Bridging the gap between motor imagery and motor execution with a brain-robot interface

Motor imagery and motor execution both cause similar changes in brain oscillations over spatially almost identical cortical areas. Because of this finding, motor imagery has been suggested as a backdoor to the motor system in stroke rehabilitation.  Yet, neuroimaging and lesion studies suggest that the networks involved in motor imagery and execution are at least… Read more »
