Selective attention mechanisms route behaviorally relevant information through large-scale cortical networks. Although evidence suggests that populations of neurons synchronize their activity to preferentially transmit about attentional priorities, it is unclear how synchrony across a network accomplished. Based on its anatomical connectivity with the cortex, we hypothesized pulvinar, thalamic nucleus, regulates synchrony. We mapped pulvino-cortical networks within visual system, using...
A typical scene contains many different objects, but the capacity of visual system to process multiple stimuli at a given time is limited. Thus, attentional mechanisms are required select relevant objects from among competing for processing. Evidence functional magnetic resonance imaging (MRI) in humans showed that when present simultaneously field, their cortical representations within object recognition pathway interact competitive, suppressive fashion. Directing attention one counteracts...
The human visual system contains an array of topographically organized regions. Identifying these regions in individual subjects is a powerful approach to group-level statistical analysis, but this not always feasible. We addressed limitation by generating probabilistic maps topographic areas 2 standardized spaces suitable for use with adult brains. Using standard fMRI paradigms, we identified 25 large population (N = 53) and transformed them into either surface- or volume-based space. Here,...
The functions of prefrontal cortex (PFC) areas are constrained by their anatomical connections. There is little quantitative information about human PFC connections, and, instead, our knowledge primate connections derived from tracing studies in macaques. subcortical areas, which white matter penetration and hence diffusion anisotropy greatest, can be studied with diffusion-weighted imaging (DWI) tractography. We therefore used DWI tractography four macaque 10 hemispheres to compare the...
Functional magnetic resonance imaging studies have shown that human ventral visual cortex anterior to area V4 contains two field maps, VO-1 and VO-2, together form the occipital (VO) cluster (Brewer et al., 2005). This is characterized by common functional response properties responds preferentially color object stimuli. Here, we confirm topographic characteristics of VO describe new maps are located VO-2 extending across collateral sulcus into posterior parahippocampal (PHC). We refer these...

Theories of spatial attentional control have been largely based upon studies patients suffering from visuospatial neglect, resulting circumscribed lesions frontal and posterior parietal cortex. In the intact brain, attention has related to a distributed frontoparietal network. Little is known about nature mechanisms exerted by this Here, we used novel region-of-interest approach relate activations network recently described topographic areas in cortex [frontal eye field (FEF), PreCC/IFS...
Single-cell studies in the macaque have reported selective neural responses evoked by visual presentations of faces and bodies. Consistent with these findings, functional magnetic resonance imaging humans monkeys indicate that regions temporal cortex respond preferentially to However, it is not clear how areas correspond across two species. Here, we directly compared category-selective macaques using virtually identical techniques. In macaque, several face- body part–selective were found...
