Projections to the basis pontis from the superior temporal sulcus and superior temporal region in the rhesus monkey

Schmahmann, Jeremy D., Pandya, Deepak N.·1991·Journal of Comparative Neurology

Abstract

The present investigation was designed to determine the origins in the temporal lobe, and terminations in the pons, of the temporopontine pathway. Injections of tritiated amino acids were placed in multimodal regions in the upper bank of the superior temporal sulcus (STS), and in unimodal visual, somatosensory, and auditory areas in different sectors of the lower bank of the STS, the superior temporal gyrus (STG), and the supratemporal plane (STP). The distribution of terminal label in the nuclei of the basis pontis was studied using the autoradiographic technique. Following injections of isotope into the multimodal areas (TPO and PGa) in the upper bank of the STS, intense aggregations of label were observed in the extreme dorsolateral, dorsolateral, and lateral nuclei of the pons, and modest amounts of label were seen in the peripeduncular nucleus. The caudalmost area TPO projected in addition to the ventral and intrapeduncular pontine nuclei. The second auditory area, AII, and the adjacent auditory association areas of the STG and STP contributed modest projections to the dorsolateral, lateral, and peripeduncular nuclei, but generally spared the extreme dorsolateral nucleus. The lower bank of the STS, which subserves central vision, the somatosensory associated region at the fundus of the rostral STS, and the primary auditory area did not project to the pons. The higher order, multimodal STS contribution to the corticopontocerebellar circuit may provide a partial anatomical substrate for the hypothesis that the cerebellum contributes to the modulation of nonmotor functions.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Requirement 1 (main MFa input to cerebro-cerebellum originates from a non-motor area and is relayed by PN) is common for several cortical areas, including prefrontal, parietal association, superior temporal, occipitotemporal and parahippocampal areas.

    “The requirement 2 is the key because the requirement one is common for several cortical areas, including prefrontal areas (Schmahmann and Pandya, 1997), parietal association areas (Schmahmann and Pandya, 1989), superior temporal areas (Schmahmann and Pandya, 1991), occipitotemporal and parahippocampal areas (Schmahmann and Pandya, 1993).”

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.
