4.9.5 Triggering on Extracted Parameters
Similar to the triggering on raw data streams, you can also define a threshold for an extracted
parameter stream to generate trigger events. For example, you can trigger the recording only
if the spike rate reaches a threshold level.
 Select the appropriate parameter data stream and channel from the Channels list.
 If you select the option Negative Slope, the fall of the parameter curve is regarded.
If you select Positive Slope, the rise is considered.
 If you use a Parameter stream with multiple extracted parameters you have to specify
the parameter type as well.
4.9.6 Time Based Trigger
You also can define a time-based trigger. The trigger event can either occur periodically
or at specified points of time. For example, you can use this feature if you want to apply
a drug at specific time intervals and want to record data only at the drug application times.
