Visual Prostheses

The ProsthesisSystem object defines a common interface for all retinal prostheses (‘bionic eyes’), consisting of an ElectrodeArray and a Stimulus. Stimuli can be assigned to the various electrodes in the electrode array, who will deliver them to the retina. A mathematical model is then used to compute the neural stimulus response and predict the resulting visual percept.

pulse2percept currently provides the following devices:

• epiretinal (placed on top of the retinal surface): ArgusI, ArgusII
• subretinal (placed next to the bipolar cells): AlphaIMS, AlphaAMS

Planned additions: PRIMA (Pixium Vision), BTV Bionic Eye (Bionic Vision Technologies).

Note

Users are free to create their own Electrode, ElectrodeArray, or ProsthesisSystem (see Extending pulse2percept).
