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.

Pause: When checked, the display will pause. The activity map will resume when the box is clicked again to clear.
Reset Button: Press to restart the display of the firing rates.
Maximum Scale Range: Allows the user to set the maximum value of the Color Scale.
Scale Eccentricity: This setting allows the user to set how eccentric and sensitive the colors are to the firing rates.
Time Constant: A time specified in seconds is how long each electrode area color will retain prior to returning to blue.
Load Map File: A map file can be loaded to change the layout of the grid.
File Storage
Use the File Storage Interface screen to record data. The user can enter patient information and select a path for the
files that are created when the session is initiated. The NeuroPort® Software assigns a numeric name to the files.
The numeric file name indicated the data and time of recording. For example, 20110124-152145 indicated that the
data file was recorded on January 24, 2011 at 3:21:45 PM. File Storage will also save the settings, in the same folder
as the data file, at the beginning of a recording session.
