Processing a Neurological Multiunit-Activity Signal

Multiunit activity (MUA) is the superimposed neuronal signal collected from a region of neurons. The code for this Demonstration is based on the MUA preprocessing methods adopted in [1] and [2]. We can visualize what kind of changes one could observe by changing the sampling frequency and filtering frequency for various standard functions (or signals), as if they had been processed from an actual raw MUA signal.

The content of this Demonstration is a part of my master's thesis research (used for MUA signal processing) at Dr. Michel A. Lemay's lab.
