As shown in Figure 11 the devices peristaltic pumps can be started and stopped by clicking the
Manual
button, so it lights up green. Then clicking on any of the channel buttons will start the pump at the
currently set pump speed for the channel. No more than two pumps should be activated at one time.
The pump speed can be changed on the
Main
screen.
Program / Channel Settings / Setup
The
Program
button on the
Main
screen leads to the
Channel Settings / Setup
screen (Figure 12). In the
top left corner, the slot ID for the current paradigm can be selected or changed. This ID is also displayed
on the
Main
screen. This table like screen quickly visualizes the settings for each channel.
Figure 12 - Channel Settings / Setup screen to change paradigm, stimulus, and rinse timings
The specific settings on this page will be used each time a stimulus ID is called via one of the slots on the
next page (
Paradigm Settings / Sequence
Figure 14). The volume for each channel is signified by a
multiplier that roughly equals 1 drop for distilled water. Please note that the exact number of drops
depends on the liquid used, mouthpiece rotation and other parameters. It is better to rely on actual
volume than drops. The time in seconds after drop delivery called
Response
time to allow for a subject
response via a visual cue before the rinse cycles start. The number of rinses is set generally for the
whole paradigm below as the
Repeat
parameter in the row called
Rinse
. Here also the
Duration
after
each rinse, the rinse
Volume,
and the number of optional
initial rinses
at the start of the paradigm can
be set here. During the execution of the paradigm loop the rinse cycle is followed by a
Rest
period that
can be set for each stimulus. At the bottom of the screen an initial
paradigm delay
(for example to allow
for MRI dummy scans) can be set. A
Paradigm Loops
parameter can be used to execute the sequence as
set in the next page more than once.
