摘要：

Effective neural stimulation requires adequate parametrization. Gaussian -process (GP) -based Bayesian optimization (BO) offers a framework to discover optimal stimulation parameters in real time. Here, we first provide a general protocol to deploy this framework in neurostimulation interventions and follow by exemplifying its use in detail. Specifically, we describe the steps to implant rats with multi -channel electrode arrays in the hindlimb motor cortex. We then detail how to utilize the GP -BO algorithm to maximize evoked target movements, measured as electromyographic responses. For complete details on the use and execution of this protocol, please refer to Bonizzato and colleagues (2023).1
