title: A rabbit head holder for attachment to a conventional stereotaxic machine.
abstract: A device is described for holding the head of a rabbit in a stereotaxic apparatus, employing the principle of anchorage by counter thrust applied between orbital clamps and a plate inserted against the upper molars, which bears the weight of the head. Rotation in the sagittal plane is accomplished by pivoting the head-holder assembly on a U-frame which bolts to a conventional stereotaxic machine. Rigid support of the head by this device has been proven in many experiments, and accurate reproducibility of stereotaxic placement of probes with reference to bregma has been confirmed in animals within limited ranges of size.
