Abstract

In two previous communications1 we have discussed the galvanic reaction in normal and in unilaterally and bilaterally labyrinthectomized guinea pigs. The present study has to do with the galvanic reaction in guinea pigs in which the eighth nerve on one side was destroyed.

Dohlman2 experimented with the galvanic reaction of animals in which the vestibular nerves were sectioned intracranially or in which the vestibular ganglion had been removed. He concluded that elicitation of galvanic nystagmus is dependent on integrity of the cells in the vestibular ganglion and their central connections. This conclusion is in agreement with that of Blau,3 who found in cats, guinea pigs and an ape that nystagmus could still be elicited with the galvanic current when the labyrinth was completely destroyed. He proved by microscopic examination of the temporal bone that Scarpa's ganglion cells and the eighth nerve were still intact in these animals. Malassez,4 after conducting
