period can range from 1 to 180 seconds. The percentage range is from 0 to 99%, 50% is typical. When set to
zero, the presentation of stimulus will not stop, and the current time-score percentage will be recorded.
9.5.10 VS_Visits
Visit-Score Visits: The presentation of stimulus can be stopped when exhaustion has been detected by
measuring the number of visits to the detection grids over a specified rolling period in seconds, The period can
range from 1 to 180 seconds. The number range is from 0 to 99. Practically the number of visits is limited by
the equation: VS_Visits = Period*Rep_Rate/2. However, no checks or corrections are made if the equation is
not true. When set to zero or if the noted equation is not true, the presentation of stimulus will not stop and
the current number of visits within the specified period will be recorded.
9.5.11 Rep_Rate
This parameter is non-editable. It is used to inspect and verify the REP RATE of the Treadmill Controller which
is automatically detected and displayed in real time: [0, 1, 2, 3]Hz. If zero, check the cable connections of the
system. The REP RATE indicator on the Treadmill Controller and any enabled treadmill lanes should flash in
unison.
9.5.12 Begin Experiment
Once all the previous parameters have been set, now is the time to load the subjects into the treadmill lanes.
•
Press the RESET button on the Treadmill Stimulus Detection to begin monitoring the stimulus on all
enabled channels.
•
Press the ODOMETER RESET button on the Treadmill Controller to initialize the odometer to zero or
load the duration values.
•
Then press the MODE button accordingly to set the treadmill belt in motion.
9.5.13 Experiment: Data View
Once the experiment has started, the screen will display the Data View. The currently selected channel to
display is in the upper left corner. The channel will be ON if the stimulus is enabled or OFF if it has been
stopped. The upper right corner will display the various data types and their current value. If the label of the
data type appears in all upper-case values, then that data type can automatically stop the presentation of
stimulus. If it appears in all lower-case letters, then it cannot. The bottom line reports the total distance
traveled by the subject of that channel.
The CHANNEL knob is used to select one of the active channels and to view its data on the screen.
The UP/DOWN knob is used to select one of the data types to view. When the stimulus has been automatically
stopped, an asterisk (*) will appear next to the label of the data type which triggered it. When stopped, the
current values of all data types for that channel will be frozen for later review.
If you would like to manually stop the presentation of stimulus for the currently selected channel, then press
the ENTER button. The channel will toggle from ON to OFF and all the data types will be frozen at their current
values for review. You may resume the presentation of the stimulus by pressing the ENTER button again. A
channel that has been automatically stopped cannot be resumed.
