The complex wheel add-on for Rat RotaRod introduce an additional complexity element for the animal to be tested thanks to the asymmetrical and adjustable rungs which increase the test sensitivity and add a higher involvement of motor cortex and hippocampus, as compared to the classic rotarod test.
The Ugo Basile RotaRod is the 1st and original, invented after the Dunham and Miya method (1957) and today has more than 6,200 citations in the literature.
The complex wheels for Rat RotaRod include 22 removable rungs, which allow for complete control of the task difficulty and therefore of the engagement of motor cortex and hippocampus, in addition to the increase of the test sensitivity.
The complex wheels for Rat RotaRod are suitable only for Rat RotaRod SKU 47750.
The complex wheels for Mouse and Rat RotaRod include removable bars, which allow for complete control of the task difficulty and therefore of the engagement of motor cortex and hippocampus, in addition to the increase of the test sensitivity.

What Nagai et al. showed in their 2017 paper is that mice undergoing complex wheel experiments consolidate during sleep a motor skill that engages motor cortex and hippocampus much more than in the traditional rotarod test.
This is potentially due to the increased complexity of movements that happen thanks to the irregular rung patterns in the complex wheel task.
