Add the devices you need for your research
Based on the experiment you want to automate, you can choose not only walls, but also the research devises that attach to them. Whether it is a tether that attaches to your subject via a commutator or a 3rd party measuring device, they can be integrated in your PhenoTyper. The walls accommodate attachments for a number of accessories, such as a feeding station, drinking bottles, CognitionWall, and shelters. You can connect a wide variety of stimulus and monitoring devices via the USB-IO box to the PhenoTyper cage. This page contains examples of add-ons and applications.
With the PhenoTyper we have several standard shelters for animals with both dark and light coat colors. These shelters are available for rats and mice and can be attached to a corner of the cage so they will be in a fixed position during your experiment. Entry holes can be monitored automatically with EthoVision XT so you can count visits and duration of stay. You can even detect if the animal is on top of the shelter as was demonstrated by this paper.
In case you want to observe the animal inside the shelter we have an IR translucent option making the black shelter appear as made of glass in the video. This is all possible because of the combination of the integrated infrared lighting and camera that the PhenoTyper can provide. Behaviors inside the shelter can thus be observed and analyzed with EthoVision XT and The Observer XT.

The pellet dispenser is an indispensable tool in reinforced-based conditioning tasks. On command it can deliver food pellets and provide feedback whether a pellet is dropped or when the pellet silo is empty. The control of the pellet dispenser is fully compatible with EthoVision XT, so you can drop pellets based on the most sophisticated and interactive test protocols that involve the reinforcement of specific behaviors.
Every pellet dispenser comes with a 20mg or 40mg pellet carousel that are color coded and can easily be swapped between experiments

Drinking behavior with the Lickometer
The Lickometer detects contact made with the spout of a water bottle, by means of detecting change in capacitance between the spout and the metal plate situated beneath the cage. This technology differs from conventional technology where the animal becomes part of an electrical circuit that involves a current flow passing through the animal. Data from the lickometer is sent to the I/O box and ultimately to EthoVision XT where its data is combined with other data such as video tracking.

The Noldus USB-IO box is a device that enables EthoVision XT to communicate directly with external equipment, such as the lickometer, levers, or the light and sound stimuli in the top unit. It allows you to benefit from all the different options for completely automated set-ups that EthoVision XT offers. This even includes set-ups with multiple cages and multiple animals per cage, in synchrony with external physiological signals.
Wheels for rats and mice
For mice we have the PhenoWheel that measures each rotation that a mouse makes while inside the running wheel. It is designed to be connected to the I/O box so its data ends up in EthoVision XT. You use EthoVision XT to measure the amount of time spent in the running wheel and the revolutions it made while on the wheel. The wheel is easy to clean and is attached directly to one of the PhenoTyper walls.
For rats we have the Activity Wheel, which is a running wheel that is connected to the outside of a PhenoTyper cage. It is connected with the PhenoTyper via a drop down door, which can be opened and closed in order to allow or prevent access. The wheel has an electronic brake with nine resistance levels, and an LCD counter display.
The rotations of the Activity Wheel are measured by means of a magnet and a magnetic sensor. The PhenoCounter module counts the number of rotations (four counts per revolution) and sends this information to EthoVision XT. In addition to this, you can use EthoVision XT to measure the amount of time spent in the Activity Wheel. The data from the counter module can also be used as a condition in test protocols that are executed by EthoVision XT.

Mouse Feeding Monitor
The Mouse Feeding Monitor (MFM) is a low-cost, easy-to-clean, and reliable solution designed to monitor the interaction of a mouse with the stainless-steel feeder, that comes with your PhenoTyper. Based on a beam break mechanism the MFM can register interaction duration and frequency, which correlates with the disappearance of food. This IR beam is pulsating at a frequency of 38kHz; this ensures that any other IR sources cannot interfere with its operation.
The MFM is connected to EthoVision XT for collecting and analyzing the data from the MFM so it can be incorporated with your tracking data.

Not only add-ons make your PhenoTyper varied, the walls are also customizable to suit your set-up. Think of different sizes, openings, connections and for add-ons. Custom options for your particular research are also possible. It all depends on your research.
