    Neurosurg Focus 27:E6. 2009
    ..The theory of operation of visual prostheses is discussed, along with a review of the current state of knowledge. Finally, the visual prosthesis is proposed as a model for a general high-fidelity machine-brain interface...

  1. Thalamic Visual Prosthesis
    John S Pezaris; Fiscal Year: 2010
    ..As proposed here, an important step in making a device like that is to understand how complicated it needs to be in order to be useful and to test a prototype in an animal model. ..
