Brain stimulators are used to treat a variety of disorders, and their range of uses continues expand. However, one problem with long-term stimulation of neural tissue is the need to increase the stimulation parameters to continue to maintain the same clinical effect. This is thought to be due to local tissue reaction to the implanted foreign body. Because the implanted stimulator functions by means of contact with functional cells within the tissue, prevention of tissue reaction to the stimulator would make a significant improvement to the device's performance and longevity.It is proposed that coating a neural stimulator device with decorin, and / or homologous molecules of functional or structural likeness to decorin, can function to decrease gliosis and other local tissue reaction in neural tissue. The present invention provides a novel system and method of device design and utilization that can prevent and suppress known associated tissue reactions associated with neural modulation of tissue with an implanted device, thereby improving the device's performance and longevity.

Described is a system for action selection based on a combination of neuromodulatory and prefrontal cortex models. The system inputs group attack probability estimates for multiple groups in a prefrontal cortex (PFC) input area of a model instance.

The activation is propagated to an action area and a neuromodulatory area of the model instance. An action strategy is selected in the action area. The action strategy is implemented, and a reward and a cost is generated for the implemented action strategy. An assessment of possible action strategies is updated based on the generated reward and cost. Each model instance modulates its subsequent action strategy selection based on the updated assessment of the possible action strategies.
