While not used in this specific paradigm a respiratory trigger condition can be automatically tied to the
onset of the valve open time of
Channel 1 . If set, the program will wait to proceed with opening valve 1
until an inhalation onset is detected on the connected respiratory belt. To add such a trigger condition
or simply change the timing of the currently defined stimulus, click on the Channel visual in the group
preview. The selected definition will now be marked with a gray background and the settings are loaded
into the valve configuration tab to the left.
Figure 42 - Respiration trigger condition denoted by red RT selected in group. Uncheck checkbox and apply change to remove.
To use the inhalation, trigger the Synchronize stimulus onset with inhalation checkbox needs to be
selected. Hit the Apply changes button to accept the new definition (Figure 42). To reverse simply re-
select the definition in the group settings tab and uncheck the checkbox in the valve configuration tab.
Apply changes again and proceed to adding visual stimuli. More detailed information on potential
trigger conditions can be found in the section
Using triggers in this manual .
It is possible to open multiple channels at once or in complex cascades. Additionally, added valves will
be automatically appended behind the first track of the current device. The concept of
Tracks allows the
user to easily shift olfactory stimuli in parallel. Tracks can be set via right click in the context menu in the
group settings view (Figure 43). Ultimately the composed group, when added to the paradigm, will be
condensed into a visual preview of vertically overlapping events (Figure 44).
Figure 43 - Olfactory stimuli within one group can be moved past each other or into different tracks via the context menu.
Vertically aligned events will automatically execute at the same time during paradigm execution.
