A simple yet reliable method for implanting rats with durable monopolar cortical electrodes, using miniature self-tapping screws, was recently reported. The paper describes the details of modifications in that method to adapt its use to larger laboratory animals. Four adult cats were implanted using the modified technique and evaluation of their records demonstrated highly consistent VERs over extended periods of time, and direct comparison with conventional wire electrodes revealed no essential differences.
