I've seen a couple of examples of creative "jury-rigging" that work
well--basically using a gas mask or gas chamber arrangement to put the
rat down so you can install him in the stereotax, then maintaining
aneasthesia via a Tygon or latex tube which terminates in the area
around the rat's nose. You can use parafilm or a large syringe or cut
plastic bottle to make a little gas mask. We also do ours in a fume
hood, to minimize our exposure to the halothane.
