Apparatus for rmTBI using the mouse as subject. The essential components of the apparatus are shown and depict (A) a photograph of the entire assembly comprised of a vertical guide tube for the dropped weight situated above the mouse stage and collecting sponge; (B) a photograph of the slit aluminum sheet that serves as the mouse stage above the collecting sponge; (C) a still captured from a video recording showing the positioning of the mouse on the stage immediately prior to head impact by the falling weight; and (D) a still captured from a video showing the mouse approximately 30 msec after head impact, illustrating the resulting 180° rotation of the mouse after head impact and ensuing acceleration/rotation.
