“…The homologies between areas of the marmoset visual cortex and those usually recognized in Old World monkeys have been summarized recently (Palmer and Rosa, 2006a), but will be mentioned briefly here where appropriate, to place our results in context. We have defined the boundaries of cortical fields projecting to DM based primarily on histological characteristics, guided by cytoarchitectural and myeloarchitectural criteria that have been previously validated against electrophysiological and connectional data (Rosa et al, 1997Rosa and Elston, 1998;Rosa and Tweedale, 2000;Burman et al, 2006Burman et al, , 2008Palmer and Rosa, 2006a,b). While an extensive review of these criteria is beyond the scope of the present paper, here we summarize the cardinal features of several areas that are key to the interpretation of our results.…”

“…Parietal projections to DM were densest from the dorsal subdivision of the posterior parietal cortex, with distinct foci of labeled neurons present in a rostral region, which has the architectural characteristics of the ventral and lateral intraparietal areas (VIP/ LIP; see section C), and in a caudal region, which is likely to correspond to the medial intraparietal area (MIP; see sections D-E). Finally, weaker projections were observed to originate from the ventral subdivision of the posterior parietal cortex (fields OPt and TPt, in section B), from the ventral inferior temporal (ITv) and parahippocampal (TF) regions, and from the frontal cortex within and around the frontal eye field [area 8Av of Burman et al (2006)]. While this areal pattern was consistently observed, the exact location of the labeled patches and, in some cases, the density of the projections, varied depending on the visuotopic location of the injection sites.…”

“…The cortical belt located immediately rostral to DM, at the dorsal occipitoparietal transition, provides a relatively direct anatomical link between the extrastriate and somatomotor cortices (Burman et al, 2006). For example, even a slight involvement of this region in case CJ25-FE (Fig.…”

“…It has been hypothesized that this region ["medial subdivision of the posterior parietal cortex" (PPm) in Fig. 2] corresponds to the macaque's area V6A (Burman et al, 2006). However, it remains unclear whether DI, DA, and PPm refer to functionally distinct areas, or to different sectors of a functional gradient [for discussion of this problem, see Rosa and Schmid (1995)].…”

Connections of the Dorsomedial Visual Area: Pathways for Early Integration of Dorsal and Ventral Streams in Extrastriate Cortex

The dorsomedial area (DM), a subdivision of extrastriate cortex characterized by heavy myelination and relative emphasis on peripheral vision, remains the least understood of the main targets of striate cortex (V1) projections in primates. Here we placed retrograde tracer injections encompassing the full extent of this area in marmoset monkeys, and performed quantitative analyses of the numerical strengths and laminar patterns of its afferent connections. We found that feedforward projections from V1 and from the second visual area (V2) account for over half of the inputs to DM, and that the vast majority of the remaining connections come from other topographically organized visual cortices. Extrastriate projections to DM originate in approximately equal proportions from adjacent medial occipitoparietal areas, from the superior temporal motion-sensitive complex centered on the middle temporal area (MT), and from ventral stream-associated areas. Feedback from the posterior parietal cortex and other association areas accounts for Ͻ10% of the connections. These results do not support the hypothesis that DM is specifically associated with a medial subcircuit of the dorsal stream, important for visuomotor integration. Instead, they suggest an early-stage visual-processing node capable of contributing across cortical streams, much as V1 and V2 do. Thus, although DM may be important for providing visual inputs for guided body movements (which often depend on information contained in peripheral vision), this area is also likely to participate in other functions that require integration across wide expanses of visual space, such as perception of self-motion and contour completion.

Tree shrews are small squirrel-like mammals that are the closest living relative to primates available for detailed neurobiological study. In a recent study (Remple et al. [2006] J. Comp. Neurol. 497:133-154), we provided anatomical and electrophysiological evidence that the frontoparietal cortex of tree shrews has two motor fields (M1 and M2) and five somatosensory fields (3a, 3b, S2, somatosensory caudal area [SC], and parietal ventral area [PV]). In the present study, we injected anatomical tracers into M1, M2, 3a, 3b, SC, and posterior parietal cortex to establish the ipsilateral cortical connections of these areas. The results provide evidence for a number of new cortical areas including medial motor and somatosensory areas (MMA and MSA), three posterior parietal areas (PPd, PPv, and PPc), and an area ventral to temporal inferior cortex (TIV). Ml receives topographic projections from M2, MMA, 3a, and PPv, and nontopographic connections from the temporal anterior and dorsal areas (TA and TD), PPc, TIV, and MSA. The connections of M2 are similar to those of M1, except that M2 receives denser projections from TIV, PPc, and dorsal frontal cortex and sparser input from M1. Areas 3a, 3b, and SC receive dense topographic projections from each other, S2, and PV and sparser connections from PPd and PPv. Area 3a receives additional input from posterior parietal and temporal regions and from M1 and MMA. Overall, the frontoparietal connections of tree shrew cortex are most similar to those of prosimian primates and quite different from those of more distant relatives such as rats.

The cortical and subcortical forebrain connections of the marmoset prefrontal cortex (PFC) were examined by injecting the retrograde tracer, choleratoxin, and the anterograde tracer, biotin dextran amine, into four sites within the PFC. Two of the sites, the lateral and orbital regions, had previously been shown to provide functionally dissociable contributions to distinct forms of behavioral flexibility, attentional set-shifting and discrimination reversal learning, respectively. The dysgranular and agranular regions lying on the orbital and medial surfaces of the frontal lobes were most closely connected with limbic structures including cingulate cortex, amygdala, parahippocampal cortex, subiculum, hippocampus, hypothalamus, medial caudate nucleus, and nucleus accumbens as well as the magnocellular division of the mediodorsal nucleus of the thalamus and midline thalamic nuclei, consistent with findings in the rhesus monkey. In contrast, the granular region on the dorsal surface closely resembled area 8Ad in macaques and had connections restricted to posterior parietal cortex primarily associated with visuospatial functions. However, it also had connections with limbic cortex, including retrosplenial and caudal cingulate cortex as well as auditory processing regions in the superior temporal cortex. The granular region on the lateral convexity had the most extensive connections. Based on its architectonics and functionality, it resembled areas 12/45 in macaques. It had connections with high-order visual processing regions in the inferotemporal cortex and posterior parietal cortex, higher-order auditory and polymodal processing regions in the superior temporal cortex. In addition it had extensive connections with limbic regions including the amygdala, parahippocampal cortex, cingulate, and retrosplenial cortex.
