“…Macaque anterior parietal lobe areas (PF, PG) and AIP are functionally connected to the ventral premotor area, whereas the posterior parietal lobe (OPt) and IPS (AIP, VIP, PEa) are connected to the caudal dorsolateral cortex. In macaques, premotor and anterior parietal regions are known to be involved in the reaching and grasping systems (Bonini et al 2012;Caminiti et al 1996;Gharbawie et al 2011;Marconi 2001), while dorsal prefrontal and posterior inferior parietal lobe (IPL) areas are known to be involved in the oculomotor control and spatial attention in macaques (Andersen 1989;Andersen and Cui 2009;Barash et al 1991;Bisley and Goldberg. 2003;Colby et al 1996;Munoz and Everling 2004).…”

“…The frontoparietal cortex in Old World primates is involved in a plethora of cognitive functions, including working memory, attention, task-switching, response suppression, grasping, reaching, and eye movement control (Andersen 1989;Andersen and Cui 2009;Barash et al 1991;Bisley and Goldberg,M.E. 2003;Bonini et al 2012;Caminiti et al 1996;Colby et al 1996;Gharbawie et al 2011;Marconi 2001;Munoz and Everling 2004).…”

Frontoparietal networks contribute to complex cognitive functions in humans and macaques such as working memory, attention, task-switching, response suppression, grasping, reaching, and eye movement control. However, little is known about the organization of frontoparietal networks in the New World common marmoset monkey (Callithrix jacchus) which is now widely recognized as a powerful nonhuman primate experimental animal. In this study, we employed hierarchical clustering of interareal BOLD signals to investigate the hypothesis that the organization of the frontoparietal cortex in the marmoset follows the organizational principles of the macaque frontoparietal system. We found that the posterior part of the lateral frontal cortex (premotor regions) was functionally connected to the anterior parietal areas while more anterior frontal regions (frontal eye field (FEF)) were connected to more posterior parietal areas (the area around lateral intraparietal area (LIP)). These overarching patterns of inter-areal organization are consistent with a recent macaque study. These findings demonstrate parallel frontoparietal processing streams in marmosets and support the functional homologies of FEF-LIP and premotor-anterior parietal pathways between marmoset and macaque.

Functional Organization of Frontoparietal Cortex in the Marmoset Investigated with Awake Resting-State fMRI

Frontoparietal networks contribute to complex cognitive functions in humans and macaques, such as working memory, attention, task-switching, response suppression, grasping, reaching, and eye movement control. However, there has been no comprehensive examination of the functional organization of frontoparietal networks using functional magnetic resonance imaging in the New World common marmoset monkey (Callithrix jacchus), which is now widely recognized as a powerful nonhuman primate experimental animal. In this study, we employed hierarchical clustering of interareal blood oxygen level–dependent signals to investigate the hypothesis that the organization of the frontoparietal cortex in the marmoset follows the organizational principles of the macaque frontoparietal system. We found that the posterior part of the lateral frontal cortex (premotor regions) was functionally connected to the anterior parietal areas, while more anterior frontal regions (frontal eye field [FEF]) were connected to more posterior parietal areas (the region around the lateral intraparietal area [LIP]). These overarching patterns of interareal organization are consistent with a recent macaque study. These findings demonstrate parallel frontoparietal processing streams in marmosets and support the functional similarities of FEF–LIP and premotor–anterior parietal pathways between marmoset and macaque.
