Assessment of LFP Source Chronic Stability Using Directional Leads in a Large-Animal DBS Model

Directional deep brain stimulation (DBS) leads provide programming flexibility but also increases programming complexity. Local field potential (LFP) neural signals sensed by directional DBS leads may provide objective information to inform DBS programming. Here, we report long-term chronic stability of LFP signals of interest (SOI) recorded from directional DBS leads in a sheep model of DBS.
