Single Neural Channel
This app displays the activity of a single channel. It is also where units can be defined for the manual spike-sorting
algorithms.
Figure 38 - Single Neural Channel
o Channel ID: From the drop down box, change the channel displayed.
o Auto: Toggles thresholding between adaptive threshold and a user defined fixed value.
o Properties: Display and change the settings of the current channel.
o Spike Display: The signal is displayed as time stamped events. Use the vertical slide button at the right of the screen to
set the voltage range. The default time scale of the spike display window is 1.6 ms / 48 samples spike width. The time
scale / spike width samples can be defined in the Global Settings section in the Hardware Configuration module in a
range from 1.0 ms to 4.3 ms (30 samples to 128 samples).
o Clear: This button clears the spike display until new spikes are triggered. Specify in the drop down box how many
events will be displayed before clearing.
o Spike Count Drop Menu: Specify how many spikes are displayed before the screen is refreshed.
o Show Spikes Drop Menu: You may specify which waveform types are displayed in the spike Display.
o Waves/Pattern: View spikes in waveform or 2D or 3D pattern view.
o Continuous: This allows the display of the continuous waveform signal and spike display in raster format.
o Raw/LNC: Click this button to display the raw data and any applicable line noise.
Manual Override options: A user can override the automatic spike sorting on an individual channel by clicking on
the Pattern view. Click the Edit button next to the classified spike to override the auto spike-sorting function for that
sorted unit and resort to a manual sorting option. Press <C> to see all available controls. Hold down the <Ctrl> key
