Modules of EthoVision XT
To know which add-on module you have, choose Help > About EthoVision XT then click the License Info button. The modules enabled in your license are marked with a check symbol.
What module is enabled depends on the EthoVision XT license is currently active on that computer. You cannot select and deselect those modules from the software. See also Types of EthoVision XT license
Base module
The Base module of EthoVision XT allows tracking of the center-point, the nose-point and tail-base point and other relevant features of one subject in one arena.
▪Tracking the nose-point is, for instance, relevant in the Elevated plus maze test to determine the number of times the subject puts its head in one of the open arms of the maze without actually entering the arm. Tracking the center-point is then not so useful.
▪You can also record your subjects’ behavior manually using the Manual Scoring function.
▪You can also measure Body elongation on the basis of thresholds that you set yourself.
note The Multiple Body Points module is included in the Base module.
You can extend the base functionality with the add-on modules listed below.
Allows tracking in more than one arena at the same time. You can track one subject per arena.
Rat Behavior Recognition module
With this module you can have EthoVision XT detect various behaviors automatically: drinking, eating, jumping, grooming, rearing (supported and unsupported), resting, sniffing, twitching and walking.
Mouse Behavior Recognition module
With this module you can have EthoVision XT detect various behaviors of mice automatically: digging, drinking, eating, grooming, hopping, rearing (supported and unsupported), resting, sniffing and walking.
important The Mouse Behavior Recognition and the Rat Behavior Recognition modules are not interchangeable. For example, you cannot use the Mouse Behavior Recognition to detect digging in rats.
With this module, you can import any external data in ASCII format. External data may include physiological data (e.g. EEG, blood pressure, heart rate, body temperature, etc.) or environmental data (e.g. room temperature, humidity, etc.).
You can synchronize track data and associated external data and subsequently visualize, select and export these data. See External Data
This module supports you in making experiments which fulfill quality requirements. It helps you protect your data and creates log files so you can easily keep track of everything that happens during a project. See EthoVision XT and Quality Assurance
This module allows you to track more than one animal per arena and study social interactions. For the statistical analysis a number of variables are available like the distance between the animals, and the relative movement. See also Advanced detection settings for tracking color-marked subjects
Trial & Hardware Control module
With this module, you can make advanced rules to start and stop the trial. You can also control hardware, like, e.g., a pellet feeder and make settings in such a way that the pellet feeder drops a pellet when the animal is in the trigger zone for 30 seconds. See Trial Control Settings in this Help and the EthoVision XT 19 - Trial and Hardware Control - Reference Manual. To find this manual, in the Window Apps screen choose Noldus > EthoVision XT 19 Other Documentation.

Track3D is a solution for tracking animals in a 3D space. This add-on includes a MATLAB application that converts 2D tracks obtained from two cameras to a three-dimensional track, and calculates a wealth of movement parameters in 3D.
Note that Track3D only works with one tracked individual at a time. For more information, contact Noldus.
