Activity Map
This app gives the user an overview of the firing rates of each electrode spatially organized over time. A map file
can be loaded to change the electrode arrangement. The spiking activity of each channel is binned and smoothed.
Binning is counting the number of spikes that occur over a fixed time window (20ms). Smoothing adds steps
between events and non-events both between channels and over time on a channel, smoothing out the event horizon
that would otherwise be too abrupt a change and could possibly cause signals to be missed by the observer.

o Pause: When checked, the display will pause. The activity map will resume when the box is clicked again to clear.
o Reset Button: Press to restart the display of the firing rates.
o Maximum Scale Range: Allows the user to set the maximum value of the Color Scale.
o Scale Eccentricity: This setting allows the user to set how eccentric and sensitive the colors are to the firing rates.
o Time Constant: A time specified in seconds is how long each electrode area color will retain prior to returning to blue.
o Load Map File: A map file can be loaded to change the layout of the grid.
