Configuration ID Panel: This panel stores the pulse configurations created by the user in the Pulses
Panel. The test pulse parameters are saved as Config 0 and should not be changed.
Stimulation Panels (6): Stimulation scripts are defined by a series of single stimulations, groups and wait
instructions.
Stimulus Panel: This feature is available when Stim Manager is set to Auto Mode. It allows the
user to select an electrode channel (1-96) and assign it to an electrode configuration from the
Configuration ID Panel. By clicking ‘Add,’ the electrode channel and electrode configuration pairs
are added to the Stimulation Script.
Group Definition Panel: Groups allow the user to generate stimuli from different current modules
at the same time. There are four basic rules for groups:
 A group must have both begin and end instructions
 A group can’t have more stimuli than enabled current modules
 An electrode can’t be used more than once in the same group
 Wait instructions cannot be used within a group
By clicking ‘Add,’ the command to begin or end a group is added to the Stimulation Script.
Wait Instruction Panel: Wait instructions allow the user to introduce delays in milliseconds to the
stimulation script. Delays can be added before or after any single stimulus or group. This command
is recommended for long delays. Short delays can be implemented using
the Interpulse delay defined in the pulse configuration. By clicking
‘Add,’ the wait instruction is added to the Stimulation Script.
Stimulation Script Window (7): This window allows the user to view the stored
sequence of stimulation events added from the Stimulus, Group Definition and
Wait Instruction Panels. Stimulation is sequential for single stimuli and
simultaneous for stimuli within a group. The maximum number of commands in
a sequence is 128.
Stimulation Script Commands (8): These command buttons begin, end, pause
and make adjustments to the Stimulation Script.
Remove: By clicking this button, the user is able to remove any single
line in the Stimulation Script.
Remove All: By clicking this button, the user is able to clear the
Stimulation Script.
Pre-Process: Once a Stimulation Script has been created, the Pre-
Process button must be selected prior to stimulation in order to:
 Send the pulse configurations to the available current
modules within the CereStim R96 unit.
 Check for correct syntax of the groups in the Stimulation Script.
 Assign a current module to each stimulus.
 Send the Stimulation Script to the CereStim R96 motherboard.
 Calculate the total elapsed time for the Stimulation Script (recorded in the Log
Window). Timing measurements depend on the pulse configurations and internal
hardware delays. The internal hardware delays are as follows:
