Get the most reliable and accurate test results with the Rotometer Activity System, widely-used and cited in research of Parkinson’s disease (PD), Traumatic Brain Injury (TBI), acquired brain injury, and spinal cord injury.  The SDI Rotometer test stations are designed to make the animal turn within its own length, which ensures exploratory behavior will not be counted as a rotation.  Additionally, you will have greater flexibility with the option to run up to 16 stations from a single computer and choosing between the full-turn or quarter-turn options.
