Summary
-
1.
Identified medial vestibular neurones were studied before, during and after nystagmogenic labyrinthine stimulation in the Encéphale isolé cat. Motor discharges were simultaneously recorded from the contralateral abducens nerve.
-
2.
87.9% of the recorded neurones showed changes in tonic firing frequency during repetitive labyrinthine stimulation with no nystagmic modulation in behaviour.
-
3.
The secondary vestibular neurones projecting monosynaptically to the contralateral abducens motoneurones were included in this non-rhythmic population.
-
4.
Only 2% of the recorded population fired rhythmically both during nystagmogenic stimulation and poststimulation nystagmus. These neurones showed plasticity in behaviour regarding the phases of nystagmus recorded from the contralateral abducens nerve.
-
5.
The remaining 10.1% of the medial vestibular neurones were excited or inhibited by repetitive stimulation of the labyrinth but showed burst firing patterns correlated with poststimulation nystagmic discharges.
