The
Program
button will lead to a selection of saved paradigms and allows to create new paradigms. The
currently selected paradigm ID is presented on the
Main
Screen on the left section of the dark blue
block labeled
Paradigm. N
. It is followed by the current subject ID as it was created in the
File Manager
.
The button
PC/Manual/Prime
opens the
Manual Mode
Screen. Here the user can open and close
individual channels as well as prime the whole system automatically. The priming feature is also useful
during the cleaning process of the Gustometer tubing (see section Cleaning procedures on page 13).
The button
PARA CHECK
simulates the execution of the paradigm to confirm on screen if timings are
accurate.
TRIG START
enables the
Input Trigger
coaxial port on the front panel. If active the paradigm
execution will be delayed until the rising edge of a 5V TTL pulse is measured on this port. The
PARA
START
button will start the execution of a program created in the
Program
screen.
The
Main
screen also allows to change the current pump speed, displayed as a percentage of the
maximum speed. The large light blue area of the screen on the bottom half of the
Main
screen displays
the current state of the device within a program. The bottom row displays the current multiplier for
channels 1-7 as well as
Rinse
for the current paradigm. The large white bar below shows the progress
during paradigm execution. Above the user can quickly see the current paradigm configuration. Starting
on the left a general delay time before the paradigm loops start is displayed. Next to it is the number
and duration of optional initial rinses.
The section to the right visualizes the actual paradigm loop with the currently used channel ID.
Stim
displays the volume (based on multiplier set below) delivered during this loop.
Res
next to it is the
allowed response time after the bolus is delivered.
Each
stimulus
application and
response
period is followed by a settable amount of rinse cycles. To clean
the pallet.
Rinse
is the number of times the system rinses with
Duration
being the time after each rinse.
That is followed by a
Rest
period until the next paradigm block in the program is administered.
Before a further explanation on the actual paradigm/
Program
designer
let’s
have a look at the
Manual
Mode
screen.
Manual mode
The
Manual
screen can be used for both priming as explained below as well as debugging and testing
each channel. It also allows to switch to PC control via the ETT Direct Control.

each channel
