Objective. Utah arrays are widely used in both humans and non-human primates (NHPs) for intracortical brain-computer interfaces, primarily for detecting electrical signals from cortical tissue to decode motor commands. Recently, these arrays have also been applied to deliver electrical stimulation aimed at restoring…
