Sensory and premotor connections of the orbital and medial prefrontal cortex of macaque monkeys

Abstract

Sensory and premotor inputs to the orbital and medial prefrontal cortex (OMPFC) were studied with retrograde axonal tracers. Restricted areas of the lateral and posterior orbital cortex had specific connections with visual-, somatosensory-, olfactory-, gustatory-, and visceral-related structures. More medial areas received few direct sensory inputs. Within the lateral and posterior orbital cortex, area 12l received a substantial projection from visual areas in the inferior temporal cortex (TE). Area 12m received somatosensory input from face, digit, or forelimb regions in the opercular part of area 1-2, in area 7b, in the second somatosensory area (SII), and in the anterior infraparietal area (AIP). Areas 13m and 13l also received a projection from the opercular part of areas 1-2 and 3b. The posteromedial and lateral agranular insular areas (Iapm and Ial, respectively) received fibers from the ventral part of the parvicellular division of the ventroposterior medial nucleus of the thalamus (VPMpc) that may represent a visceral afferent system. The dorsal part of VPMpc projected to the adjacent gustatory cortex. These restricted inputs from several sensory modalities and the convergent corticocortical connections to orbital areas 13l and 13m suggest a network related to feeding. The OMPFC was also connected to premotor cortex in ventral area 6 (areas 6va and 6vb), in cingulate area 24c, and probably in the supplementary eye field. Area 6va projected to area 12m, whereas a regio…

  • The orbitofrontal cortex is anatomically well suited to integrate exteroceptive and interoceptive sensory information to guide behavior, given lateral orbitofrontal cortex connections to sensory modalities and medial orbitofrontal cortex connections to visceral control areas.

    “With the lateral OFC's connections to sensory modalities (e.g., Barbas 1988; Rolls 1999, see Kringelbach & Rolls 2004) and the medial OFC's connections to areas involved in visceral control (e.g., Carmichael & Price 1995; Eblen & Graybiel 1995; Ongür & Price 1998; 2000; Rempel-Clower & Barbas 1998; see Kringelbach & Rolls 2004 for a review), the OFC is anatomically well suited to perform this role”

  • The orbital network has specific connections with sensory cortex, including primary olfactory and gustatory cortex, visual inferior temporal areas, the ventral bank of the superior temporal sulcus, and somatic sensory areas in the dysgranular insula and frontal operculum.

    “These include primary olfactory and gustatory cortex, visual areas in the inferior temporal cortex (TEa), and the ventral bank of the superior temporal sulcus, somatic sensory areas in the dysgranular insula (Id) and the frontal operculum (Carmichael and Price, 1995b;Saleem et al, 2008).”

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.
