Abstract / Zusammenfassung

Behavioral data of laboratory mice are often recorded in short tests using experimental setups that claim to measure very specific domains. However, it must be questioned whether the tests generate too artificial and potentially stressful situations and thus, whether the results reflect the behavior mice would exhibit under natural conditions. Instead of snapshot tests, we need a completely new approach for a holistic observation, in which the behavior of animals in their natural environment is recorded.
To approach such an ideal data collection, we present a novel system for housing and observing laboratory mice. The system consists of individual housing modules connected to a complex, large enclosure for mice. The modules are affordable, easy to assemble and suitable for use in a laboratory environment. Each module is equipped with a camera, an ultrasonic microphone, and connecting tubes with RFID antennas. A dual PC setup in combination with a self-developed hardware trigger enables continuous, synchronized recording of audio, video and RFID data. Big data is recorded in order to obtain highly detailed information about individual and group behavior. The aim of the current research project is to find focal points and patterns in the behavioral data that can be used to create test procedures based on a mouse-centric perspective. By bringing the test to the mouse instead of bringing the mouse into the test, we expect more transferable and reliable scientific data. In addition, our initial observations show that the animals really appreciate this type of housing.
