Abstract

1. 1. A number of cerebral B-neurons of Aplysia californica were activated by tactile stimulation of the statocysts and by electrical stimulation of the static nerve. Types of responses recorded included antidromic spike, monosynaptic EPSP with or without spike and polysynaptic EPSPs. 2. 2. Some of the B-neurons were inhibited by trains of electrical stimulation of the static nerve. Hyperpolarization was mostly preceded by a short increase of spiking, usually during stimulation. Some A-neurons also responded with inhibition. 3. 3. The statocyst nerve contained axons carrying information not only from the statocysts to the cerebral ganglion but also from the cerebral ganglion to the statocyst. The latter pathway could be activated by tactile stimulation of the tentacles. 4. 4. Activation of either static nerves resulted in the increase of activity of the other static nerve through the cerebral ganglion, suggesting interaction between the two statocysts.
