Implantable Optical Stimulators

A circuit arrangement for selecting and implementing neuromodulation parameters corresponding to a plurality of control channels, the plurality of control channels providing control of respective light-delivery elements, the circuit arrangement comprising:

• a sensor for sensing effects of neuromodulation due to stimuli from the light-delivery elements;
• and
• a computer operatively connected to the sensor,
• wherein the computer is configured to:
• generate sets of control data, wherein each of the sets include control information for use with the plurality of control channels;
• deliver optical stimuli in response to the candidate specification settings;
• generate correlation data about the sets of control data with the sensed neuromodulation effects;
• select one set of control data from the sets of control data, the selection responsive to the data that correlation data;
• and
• implement the selected candidate parameter setting as a treatment regimen.
