Título provisional de la tesis

Improving cortical visual prostheses using closed-loop stimulation approaches

Resumen

Previous studies have shown that is possible to restore a limited but useful sense of vision through the intracortical microstimulation of the visual cortex. A human clinical trial in which electrical stimulation is provided by a 96 channels Utah array is now under development. The results obtained with the first implanted patient showed that she was able to perceive phosphenes and that different stimulation strategies could elicit different kind of perception. Although very promising, the approach still has many open challenges to face.

The purpose of this PhD project is to try to answer to all the open questions and to try to improve the state of the actual cortical prosthesis.
