abstract: Two reliable intracerebral cannulas, with a protective cap and a locking arrangement of the extension tube can be made from inexpensive regular and dental disposable needles and syringes. The preparation and use of these alternative cannula systems which enable the prolonged intracerebral infusion of experimental substances in unrestrained, freely moving animals is described.
