newplatfphoto3.jpg LABORAS is an innovative measurement system that recognizes several behaviours of small rodents (mice and rats) fully automatically. The system is currently the only system in the market which is able to determine a large number of different behaviours without traditional human observation. LABORAS can recognize a wide range of normal behaviors (climbing, drinking, eating, grooming, immobility, locomotion and rearing( as well as special behaviors such as scratching, WDS, Head shakes, Hindlimb licking, startle and freezing. In addition the system determines the following tracking parameters: position, speed, maximum speed, traveled distance and position distribution. At the end of 2006, LABORAS release 2 was launched with an improved user interface and faster processing capability.

Examples of application areas: Ethology, (Safety) Pharmacology, Dermatology, CNS and Toxicology.

Sonotrack_system.jpg SONOTRACK is an advanced non-invasive measurement system to monitor ultrasonic sounds produced by animals. By using a dedicated microphone and hardware the system is able to pick up ultrasonic vocalizations (USV) of animals generated at frequencies between 15 kHz and 125 kHz.
SONOTRACK provides powerful tools for fully autmatic analysis of the recordings, including advanced filtering techniques for clean up of the signal, automatic call detection and is the fiirst and only system to provide call classification.
The recorded signal can be converted in a format which is audible for humans. Optionally, dedicated ultrasound amplifers and speakers allow playback of the ultrasonic recording to your animals, enabling a number of special animal models. 

Examples of application areas:
Ethology, CNS and Pharmacology, Bio Acoustics, Pain, Animal welfare studies.

SleepSign ScreenSleepSign for Animal is a further extension of the Metris portfolio. Metris distributes this product in Europe (west and east) on behalf of Kissei Comtech Japan. It enables further expansion of automated animal behavior research. SleepSign for Animal is a software package that can distinguish several sleep stages (e.g. rapid eye movement (REM), non rapid eye movement (NREM) and wake) in freely moving animals using EEG and EMG data obtained by telemetry. It offers the ability for both in-depth analysis of sleep stages and easy automated sleep stage detection. It drastically reduces the time and labour spent on sleep stage scoring and enables you to generate standard types of reports with only a few keystrokes.


Examples of application areas: Neurology, Pharmacology Research, Sleep studies.

SmartChamber ScreenSmartChamber is the latest product in the Metris portfolio. SmartChamber creates a measurement environment that is optimally isolated from the surrounding room invironment. SmartChamber provides the researcher with a measurement space in which the animal under test can be effectively blocked from external sounds, magnetic fields, unwanted visual cues, etc. The initial versions of SmartChamber are designed to be used for bio-acoustic experiments and are prepared for integration with the Metris Sonotrack system. The SmartChamber is equipped with an ultralow noise ventilator, LED light (soft white) and door switch. Optionally various extra sensors, special light (red light) and an Ultrasound Microphone can be installed.The SmartChamber is controlled by an e-Tablet in the front of the SmartChamber. Later in 2018 a complete line of SmartChambers will come available that will have various additional functions. 


Examples of application areas: Ethology, CNS and Pharmacology, Bio Acoustics, Pain, Animal welfare studies.
