1. Brain probe positioning apparatus comprising:
- a base member;
means for selectively attaching said base member to portions of the skull of a living animal;
a first translating member;
means for slidably attaching said first translating member to said base member in a first straight line;
first moving means for selectively moving said first translating member along said first straight line;
first locking means for selectively locking said first translating member against movement with respect to said base member;
a second translating member having an opening therethrough;
means for slidably attaching said second translating member to said first translating member in a second straight line transverse to the first straight line;
second moving means for selectively moving said second translating member along said second straight line;
second locking means for selectively locking said second translating member with respect to said first translating member;
a tube extending through the opening in said second translating member;
pivotal adjustment means attached to said second translating member for permitting said tube to be universally pivoted 360°
about a point; and
means for locking said pivotal adjustment means in a desired position whereby said tube will be held in said desired position with respect to said second translating member.

Abstract
A head mounted stainless steel stereotaxic apparatus for precise locallization of probes/cannulas in selected regions of the mammalian brain. Novel aspects of this apparatus include versatility in placement of probe/cannula in selected sites in the brain, mobility of the animal after attachment of the apparatus to the frontal bone, and repeated use of the same instrument on different animal species.
