Consistent Results
The GSM device has been designed to make sensitivity experiments easy and con-
sistent, thanks to its:
Effective
peak detector
, for a reliable and automated detection of the animal
response
Rate-Meter
(see paragraph 5.4) and Slope features (see paragraph 0), ensur-
ing the desired force is applied at a consistent rate
Software
, acting as a quality control tool, by showing the applied pulling force
(red line) and the desired target force rate (blue line) in real time.
The rate of application of the force (
target force rate
) is set by the operator from the con-
figuration menu (see section 4.5.1, option 1) and the GSM includes software tools that
help the operator in consistently applying the force at the desired rate.
See the below screenshot of the Grip Strength meter software showing the force trace (
in
blue
) and the desired target force rate (
in black
).
The experimenter can con-
sistently apply the force (i.er.
pull the animal) at the desired
rate, by simply making sure
that the blue trace lays on the
black line.

INSTRUMENT DESCRIPTION
The instrument basically consists of:
1)
an
electronic unit
(peak amplifier
)
2)
a
base plate
of black sand-blasted PVC, complete with a 13mm diam. upright
3)
a set of
grasping-tools
(three different shapes are provided, trapeze or T-bar)
and two
grasping-grids
4)
a
force transducer
adjustable in height, provided with connection cable &
connector to the peak amplifier
The instrument is delivered in a convenient plastic case which should be retained for the
safe storage of GSM and its accessories.
