\section{Methods}  \subsection{Filtering} \subsection{Pre-processing}  Prior filtration is implemented in order to avoid electromagnetic interferences from utility frequency, 60Hz. Thus, a simple notch filter added to the system. However, other filtration bands may be of use when considering neural signals. As used in \cite{25565947}, a band-pass filter may be implemented in an 80-120Hz range, since high-gamma power seems to have correlation with motor tasks.  \subsection{Spike detection}  There are several ways of implementing a spike detection algorithm. Other preprocessing methods can be used at this point, such as Common Average Reference (CAR) method. This tool averages all electrode inputs and removes the value calculated from all other signals in order to decrease noise contribution.  \subsection{Spike detection and frequency measurement}  There are several ways of implementing a spike detection algorithm. One could use Wavelet Transform or feature extraction methods, but none seemed to be more popular and simple than threshold detection.
