INTRODUCTION In anuran amphibians, the tegmentum mesencephali is mainly occupied by sensory centers, e.g. the torus semicircularis being an auditory center, the nucleus opticus tegmenti associated with optokinetic nystagmus, and nucleus isthmi considered as a secondary visual center, However, very little is known about physiological significance of the rest part of the tegmentum. Anatomical findings have shown that the lateral tegmentum is connected with the optic tectum, telencephalic striatum展开更多
