Several modular shuttle box packages are offered in this section for avoidance and learned helplessness studies. Shuttle box packages feature the modular shuttle box chamber with two components separated by a central divider. The ENV-010MC shuttle box chamber has a single modular bay centered at the end of each compartment to hold a stimulus light and the delivery device (sonalert). The ENV-010MD shuttle box chamber has a dual-bay modular panel at the end of each compartment, which does not alter the dimensions of the chamber itself. The same shuttle box chamber can be used for either rat or mouse, depending on the grid floor installed and the height of the photobeam sensors.
The standard shuttle avoidance software application (SOF-700RA-7) is supplied with the interface package. This application allows the user to define the number of trials to run, the stimuli (tone, light or
both), the avoid interval, the escape interval, optional CS/US overlap, the option to punish ITI crossings and the maximum session duration. A row of data is created for each trial with the trial number, an avoid or escape tag with the corresponding latency, left and right chamber activity, crossings, and punished crossings. A summary file includes total values as well as the mean avoid and escape latency.
Please contact Sales if you have any questions on these packages or require assistance in designing a package to meet your specific research requirements.
Interface, computer and software are sold separately.
This deluxe package contains a single station for active or passive avoidance, as well as many learned helplessness paradigms. By using four independent photobeams on each side of the chamber, an excellent measurement of movement activity is obtained. The chamber is divided into two sections by a removable auto guillotine door. This package also includes an MDF sound attenuating cubicle to enclose the chamber and prevent distractions during testing. Each chamber comes equipped with a stimulus light and a sonalert tone generator on each side. The grid floor is equipped with a patented quick disconnect harness which allows aversive stimulation to be delivered to either side of the chamber floor, at different times. This package also includes aversive stimulation controllers and an opaque cover for passive avoidance testing. The interface and operating software are not included in this package. Order the MED-SYST-8 interface and software package to run up to eight chambers or the MED-SYST-16 to run up to sixteen test chambers.

This basic package is designed primarily for active avoidance studies. By using four independent
photobeams on each side of the chamber, an excellent measurement of movement activity is obtained. The chamber is divided into two sections by a manual guillotine door. A small plastic hurdle is included, and can be used in place of the manual guillotine door to separate the components of the chamber. Also featured in this package is an MDF sound attenuating cubicle to enclose the chamber and prevent distractions during testing. Each chamber comes equipped with a stimulus light and a sonalert tone generator on each side. The grid floor is equipped with a patented quick disconnect harness, which allows aversive stimulation to be delivered to either side of the chamber floor, at different times. This package also includes the aversive stimulation controllers. The interface and operating software are not included in this package. Order the MED-SYST-8 interface and software package to run up to eight chambers or the MED-SYST-16 to run up to sixteen test chambers.

Pivot floor systems are available in place of the photobeam sensor package. The chamber floor rests on a central pivot point. Depending on which side of the chamber the animal is on, the floor will tilt slightly to one side or the other, engaging a microswitch that is used to determine which side of the chamber the animal is on. The pivot floor is useful when the shuttle box is set-up for video monitoring with a face-on view, as there are no infrared beam sensors to obstruct the view of the camera.
