Chronic multi-channel neural recording recently has been applied to study dynamic brain function. Often these studies rely upon chronically implanted multi-electrode arrays, raising questions about the stability of long-term neuronal recording. The objective this paper is investigate and track recorded signal activity for over 3 years in awake, behaving primate through analysis unit waveforms principle component (PCA) multi-units. For time span from beginning end session, monkey was trained do three different tasks. We show that some units are very stable within a session
