Rotamètre sans contact Rat souris

The Rotometer is an original instrument from Ugo Basile, specifically designed for recording rotations in UNRESTRAINED MICE, by measuring the animal movements via a magnetic field detection system.

The greatest advantage to this instrument is that it measures free-moving rotational behaviour; no tether required. To quantify rotational behavior in a freely moving animal is a significant development: our model accomplishes precisely this task, using new and clever technology to count clockwise (CW) and counterclockwise (CCW) rotations in a circular open field.

Simply attach a tiny magnet (the size of a grain of rice) to the animal tail or nape and the Rotometer automatically tallies clockwise and counterclockwise rotations. For long term tests, the magnet can be injected.

The injectable magnets, encapsulated within a proven bio-compatible material, fit within syringes normally used for the injection of identification transponders. These small magnets are easy to inject in the animal’s nape and do not interfere with the animal behavior.

The mouse (or small rat) is placed on a 20cm diam. circular arena, enclosed in a clear Perspex cyinder, 25cm tall. Digital read-out shows accrued rotations. The Rotometer features Portable Memory Stick technology, USB interface, & software for connection to PC, all included in the standard package.

    The Rotometer is widely used in research on motor assessment tests. Rotometer is also used in traumatic and acquired brain injury research and spinal cord injury research.

    There are several well-characterized causes for animals to exhibit rotational behavior:

    • Uneven/unilateral higher expression of levels of neurotransmitters (such as GABA or dopamine). Some brain tumors can cause aberrant expression levels to occur. Injury may also interfere with proper neurotransmitter expression, and/or cause some localized change in neurotransmitter expression
    • Developmental anomalies can also cause rotational behavior
    • Anxiety/stress may cause this aberrant behavior
    • Exposure to some drugs, or drug abuse, or withdrawal from some drugs, all may have rotational sequelae.
    • Physical lesions also can cause rotational behavior in an animal
