Nucleus prepositus
Abstract
The cytoarchitecture and the histochemistry of nucleus prepositus hypoglossi and its afferent and efferent connections to oculomotor structures are described. The functional significance of the afferent connections of the nucleus is discussed in terms of current knowledge of the firing behavior of prepositus neurons in alert animals. The efferent connections of the nucleus and the results of lesion experiments suggest that it plays a role in a variety of functions related to the control of gaze.

Oxytocin receptors are expressed in areas involved in saccadic eye movements, including the superficial grey layer of the superior colliculus, deeper layers, the oculomotor nucleus, and the nucleus prepositus.
“In areas involved in saccadic eye movements in response to visual stimuli, OXTR is expressed in the superficial grey layer of the SC (Fig. 2), as well as deeper layers, and in the oculomotor nucleus (III) and the nucleus prepositus, which are two brainstem motor nuclei that control the muscles of the eye and participate in the horizontal gaze stabilisation system, respectively (41-43).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
