VideoTrack
system has the capacity to automate the Forced Swim Test and a
variety of other behavior tests used for rodents involving general
animal
activity.

Principle
Our technology is based on video image
analysis.
A typical system is composed of various
items including an
infrared-sensitive camera with appropriate
lenses, a computer unit
equipped with special hardware, and
effective software that enables
a scientist to quantify animal
movement.
|
|
The investigator is able to define
the settings for each beaker and monitor
up to eight rodents at the same
time, depending on the size of
the beakers.
|
|
Once the experiment is set, a curve will
be generated, for each
animal, in proportion to the general
animal activity represented by
different colors.
The scientist may subsequently adjust
thresholds that will
allow for the automation of different
types of movements such as
inactivity, normal, and burst activity. At
the end of an experiment, the count and duration
of each type of movement will be
calculated.

High Accuracy in Data Supplied
VideoTrack is able to analyze groups of animals in real time.
The superior spatial resolution of 800 by 600 pixels gives
scientists the opportunity to detect refined movements.
Optional image filtering has been developed to remove potential
artifacts.
Active
Memory
While using this technology, the investigator has the ability to
design the
protocol of an experiment. At the end of the experimental process,
VideoTrack makes calculated
results and raw data storage readily available.
Also, the scientist may change the thresholds originally
set and replay the
experiment to obtain a new set of data.
