(1) The cell layers in tegmentum were indistinct.

(2) The laterodorsal tegmentum (LDT) neurons supply most of the cholinergic tone to the brainstem and diencephalon necessary for physiological arousal.

(3) The tegmentum —— tectum —— tegmentum connections are only concerned with the mid - dle and deep layers of the superior colliculus.

(4) Bilateral infarction involved the bilateral pyramidal tracts and tegmentum, represents pseudobulbar palsy and bilateral motor deficits.

(5) Objective:To study the ultrastructure of the tegmentum vasculosum(TV) in chick inner ear so as to obtain important information for its physiology and pathology.

(6) These author found that destruction of per-aqueductal gray matter and adjacent tegmentum beneath the superior colliculi abolished or greatly reduced facio-vocal behavior.

(7) From dorsal to ventral, the optic lobe can be divided into two parts: tectum and tegmentum, there is no distinct boundary between them, but the cell organization of them is different.

(8) It was discovered that there were a group of gigantic neurons scattering in the tegmentum dorsolateral to the oral half of the red nucleus in the midbrain of the rabbit.

(9) Pathologic evaluation of the lesions demonstrates necrosis (due to severe edema) in the thalami, tegmentum, and dentate nuclei.
