TLDR
A 58-year-old man developed a selective supranuclear paralysis of downgaze, which was repeatedly documented until it completely resolved after 6 weeks, with a bilaterally symmetric old infarct in the mesodiencephalic region.Abstract:
A 58-year-old man developed a selective supranuclear paralysis of downgaze, which was repeatedly documented until it completely resolved after 6 weeks. At autopsy, there was a bilaterally symmetric old infarct in the mesodiencephalic region. In common with four previous similar reports, the lesion involved structures bordering the dorsomedial aspect of the red nucleus. This same region has been implicated in the control of vertical eye movements in recent neuroanatomic and physiologic experiments in nonhuman primates.read more

Thalamic infarcts: clinical syndromes, etiology, and prognosis.
TL;DR: The delineation into four arterial thalamic territories (inferolateral, tuberothalamic, posterior choroidal, paramedian) corresponded clinically to four different syndromes and the most common etiologies were lacunar infarction, large artery atherosclerosis with presumed artery-to-artery embolism, cardioembolisms, and migrainous stroke.

The syndrome of bilateral paramedian thalamic infarction
Alan Guberman,Donald T. Stuss +1 more
TL;DR: Bilateral anterior paramedian thalamic infarction resulting from occlusion of a bilaterally distributed thalamosubthalamic paramedian artery was demonstrated on CT in two patients, forming a lacunar syndrome with characteristic clinical and CT features.

Palsy of upward and downward saccadic, pursuit, and vestibular movements with a unilateral midbrain lesion: pathophysiologic correlations.
TL;DR: Oculography demonstrated saccadic palsy above primary position and slow, limited vertical saccades below; low-gain, restricted vertical pursuit; and low- gain, abnormal phase lead, and restricted range of the vertical vestibulo-ocular reflex (VOR).

TL;DR: Decreased visually guided saccade velocity and gain are suggestive of underlying tau pathology in FTD, with vertical saccades abnormalities most diagnostic of progressive supranuclear palsy.

TL;DR: Physiological, anatomical and clinical evidence support the conclusion that this cell group is involved in the generation of vertical eye movements.

Vertical eye movement related unit activity in the rostral mesencephalic reticular formation of the alert monkey.
TL;DR: Eye movement related unit activity was recorded in the rostral mesencephalic reticular formation (MRF) of the alert monkey, and it is suggested that this region of the roStral MRF acts an an immediate supranuclear structure, mediating eye movements in the vertical plane.

Oculomotor nucleus afferents in the monkey demonstrated with horseradish peroxidase.
TL;DR: The demonstration of afferents from the contralateral interstitial nucleus of Cajal, and from the nearby rostral interInterstitial nucleus of the medial longitudinal fasciculus, predominantly ipsilateral to the injection site, confirms the significant role of these two regions as premotor structures.
