Speech stream segregation to control an ERP-based auditory BCI.

abstract：OBJECTIVE:Visual prostheses are designed to restore partial functional vision in patients with total vision loss. Retinal visual prostheses provide limited capabilities as a result of low resolution, limited field of view and poor dynamic range. Understanding the influence of these parameters in the perception results ...
