Patent ID: 8485133

Claim:
A mobile platform arrangement ( 10 ) comprising: a first platform ( 21 ) with an outer diameter d, a second platform ( 11 ) with a diameter at least 2d, and means for securing a conscious and awake experimental animal ( 51 ), said means comprising a head adapter ( 31 ) for fixation on the experimental animal's head and mounting means ( 42 ) for the head adapter, said mounting means adjusted to be connected to the head adapter ( 31 ) and advantageously disposed at the side of the first platform ( 11 ) or at a close proximity thereto, wherein the first platform ( 21 ) and the second platform ( 11 ) are implemented as flat-bottomed members; wherein the first platform ( 21 ) comprises sidewalls and a surface area therewithin; wherein the second platform ( 11 ) is provided with boundaries and a surface area therewithin; wherein the second platform ( 11 ) is adapted to accommodate the first platform ( 21 ) at the surface area within the boundaries of the second platform; wherein the surface area within the boundaries of the second platform ( 11 ) is provided with a surface structure ( 12 ); wherein the first platform ( 21 ) is positioned onto the surface structure ( 12 ); wherein the surface structure ( 12 ) is adapted to substantially reduce friction between the first platform ( 21 ) and the second platform ( 11 ); wherein the first platform ( 21 ) is adapted to perform an unobstructed gliding motion along and/or over the surface structure ( 12 ) of the second platform ( 11 ) upon providing an external acceleration force to the first platform ( 21 ).
