Hardware-software complex Rotarod+ - measurement of motor activity of rodents
Hardware-software complex Rotarod+ in the disassembled state Drum for rats

Hardware-software complex Rotarod+

The complex is designed for determination of motor-coordination disorders by the ability of small laboratory animals (rats and mice) to stay on the rotating drum.

Capabilities

  1. Detect
    • Movement disorders
    • Endurance
    • Motivational state
  2. Dosing the physical load

Based on abilities of small laboratory animals (rats and mice) to stay on the rotating drum. Motor deficit is measured by the holding time. The complex allows testing of up to 7 mice or 4 rats. Registration of holding on and falling down is performed by using infrared sensors.

The motivation's state is investigated by changing the quality of the motivational incentive:

Located under the moving drum an electric grid is used to make stimulation

Along with the ease of use of the system, a large number of variable parameters are provided that will satisfy the needs of researchers in the most diverse areas of normal and pathological physiology, pharmacology, kinesiology, neuroscience.

  1. The following parameters are determined:
    • Determining the location of the animal in the drum section
    • Duration of staying of an animal on a drum
    • Passed way
    • The speed of rotation of the drum at the time of falling and landing of an animal
    • The nature of the motivational incentive (the lack/height/water environment/electroskin irritation with grid)

  2. The following options are possible to configure:
    • The speed of rotation of the drum can be changed in real time
    • It is possible to set the script of the rotation of the drum
    • Changing the nature of the motivational incentive (the lack/height/water environment/electroskin irritation with grid)
    • There is wide range of options for electrostimulation

The hardware-software complex is created according to safety requirements of the medical equipment:
