| Résumé : | The authors' technique consists of raising the meninges and implanting small, silver, disc shaped electrodes 200 μ in diameter with an attached 1.5 cm length of wire 50 μ in cross section. The disc adheres by surface tension while the wire is inserted perpendicularly to the surface. The whole is secured by a new adhesive, a cyanoacrylate (cyanolit) which polymerizes instantly on contact with damp. The electrodes are fixed firmly in place and the pia mater is solidly anchored in the resin. It is sufficient to then cover the whole with dental cement fixed in the ordinary way to the cranial vault. Connections are then inserted to extend the electrodes. The authors demonstrate the remarkable harmlessness of this method by producing somesthetic potentials in rabbits more than 5 mth after implantation. The same technique has been used to produce cerebellar potentials in rats. In no case was it possible to demonstrate harmful effects from the resin. |
