Cingulate cortex of the rhesus monkey: II. Cortical afferents

Vogt, Brent A., Pandya, Deepak N.·1987·Journal of Comparative Neurology

Abstract

Cortical projections to subdivisions of the cingulate cortex in the rhesus monkey were analyzed with horseradish peroxidase and tritiated amino acid tracers. These projections were evaluated in terms of an expanded cytoarchitectural scheme in which areas 24 and 23 were divided into three ventrodorsal parts, i.e., areas 24a–c and 23a–c. Most cortical input to area 25 originated in the frontal lobe in lateral areas 46 and 9 and orbitofrontal areas 11 and 14. Area 25 also received afferents from cingulate areas 24b, 24c, and 23b, from rostral auditory association areas TS2 and TS3, from the subiculum and CA1 sector of the hippocampus, and from the lateral and accessory basal nuclei of the amygdala (LB and AB, respectively). Areas 24a and 24b received afferents from areas 25 and 23b of cingulate cortex, but most were from frontal and temporal cortices. These included the following areas: frontal areas 9, 11, 12, 13, and 46; temporal polar area TG as well as LB and AB; superior temporal sulcus area TPO; agranular insular cortex; posterior parahippocampal cortex including areas TF, TL, and TH and the subiculum. Autoradiographic cases indicated that area 24c received input from the insula, parietal areas PG and PGm, area TG of the temporal pole, and frontal areas 12 and 46, Additionally, caudal area 24 was the recipient of area PG input but not amygdalar afferents. It was also the primary site of areas TF, TL, and TH projections. The following projections were observed both to and within posterior cingulate cortex. Area 29a–c received inputs from area 46 of the frontal lobe and the subiculum and in turn it projected to area 30. Area 30 had afferents from the posterior parietal cortex (area Opt) and temporal area TF. Areas 23a and 23b received inputs mainly from frontal areas 46, 9, 11, and 14, parietal areas Opt and PGm, area TPO of superior temporal cortex, and areas TH, TL, and TF. Anterior cingulate areas 24a and 24b and posterior areas 29d and 30 projected to area 23. Finally, a rostromedial part of visual association area 19 also projected to area 23. The origin and termination of these connections were expressed in a number of different laminar patterns. Most corticocortical connections arose in layer III and to a lesser extent layer V, while others, e.g., those from the cortex of the superior temporal sulcus, had an equal density of cells in both layers III and V. In one instance projections to area 24 arose almost entirely from layer V of areas TH, TL, and TF. Furthermore, although most projections terminated in layers I–III of cingulate cortex, those of the amygdala to rostral area 24 terminated in deep layer I and layer II while area Opt projections to area 23 terminated mainly in layers I, II, and IV. Four classes of cortical connections have been characterized and each may play a role in the sensorimotor functions of cingulate cortex. These include connections with sensory association and multimodal areas, projections to and from premotor area 24c, subicular termination in areas 25, 24, and 29, and intracingulate connections that may transmit sensory input to areas 24 and 23 into area 24c.

  • Tract tracing studies in the Macaque monkey demonstrated that visceromotor areas receive ascending projections from viscerosensory cortex (posterior and mid-insula).

    “tract tracing studies in the Macaque monkey (Mesulam and Mufson, 1982; Mufson and Mesulam, 1982; Vogt and Pandya, 1987; Carmichael and Price, 1995) demonstrated that VMAs receive ascending projections from viscerosensory cortex (posterior and mid-insula).”

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.
