“…This basic action-matching mechanism may thus predate the chimpanzee-human split. With respect to objectdirected actions, however, chimpanzees retain a generally macaquelike pattern of brain response dominated by the "top-down" contributions of the frontal executive cortex (85,86). Humans alone display a more distributed pattern of occipital, temporal, parietal, premotor, and prefrontal activation, reflecting an increased role for bottom-up perceptual representations incorporating kinematic and spatiotemporal details about object-directed actions (85).…”

Culture suffuses all aspects of human life. It shapes our minds and bodies and has provided a cumulative inheritance of knowledge, skills, institutions, and artifacts that allows us to truly stand on the shoulders of giants. No other species approaches the extent, diversity, and complexity of human culture, but we remain unsure how this came to be. The very uniqueness of human culture is both a puzzle and a problem. It is puzzling as to why more species have not adopted this manifestly beneficial strategy and problematic because the comparative methods of evolutionary biology are ill suited to explain unique events. Here, we develop a more particularistic and mechanistic evolutionary neuroscience approach to cumulative culture, taking into account experimental, developmental, comparative, and archaeological evidence. This approach reconciles currently competing accounts of the origins of human culture and develops the concept of a uniquely human technological niche rooted in a shared primate heritage of visuomotor coordination and dexterous manipulation.brain evolution | cultural evolution | archaeology | imitation

“…We have previously used landmark-constrained registration using about two dozen landmark contours that represent areal boundaries or other functional transitions presumed to reflect evolutionary homologies (Denys et al 2004;Van Essen 2005). This approach provides evidence of hotspots of human evolution in lateral temporal, parietal, and prefrontal cortex that have expanded dramatically in the human lineage relative to that in the macaque; the pattern is remarkably similar to human postnatal cortical expansion, between birth and adulthood (Van Essen and Dierker 2007;Hill et al 2010).…”

To decipher brain function, it is vital to know how the brain is wired. This entails elucidation of brain circuits at multiple scales, including microscopic, mesoscopic, and macroscopic levels. Here, we review recent progress in mapping the macroscopic brain circuits and functional organization of the cerebral cortex in primates-humans and macaque monkeys, in particular. There are many similarities across species in terms of overall patterns of cortical gray matter myelination as well as functional areas that are presumed to be homologous. However, there are also many important species differences, including cortical convolutions that are much more complex and more variable in humans than in monkeys. Our ability to analyze structure and function has benefited from improved methods for intersubject registration that cope with this individual variability. To characterize long-distance connectivity, powerful but indirect methods are now available, including resting-state functional connectivity and diffusion imaging coupled with probabilistic tractography. We illustrate how connectivity inferred from diffusion imaging and tractography can be evaluated in relation to 'ground truth' based on anatomical tracers in the macaque. Interspecies registration between human and macaque cortex based on presumed interspecies homologies demonstrates an impressive degree of areal expansion in regions associated with higher cognitive function.

“…The relationships between the BOLD signal and local electrophysiology remain poorly understood, but fMRI studies in nonhuman primates have contributed dramatically to system and cognitive neuroscience, as well as to our understanding of the biophysical basis of the fMRI signal (Denys et al, 2004;Gamlin et al, 2006;Gretton et al, 2006;Shmuel et al, 2006). Furthermore, fMRI studies on nonhuman primates can provide a link between decades of studies with single/multiple unit and/or local field potential recordings conducted in behaving monkeys and fMRI studies in humans (Vanduffel et al, 2002;Orban et al, 2003;Tsao et al, 2006).…”

Although blood oxygenation level-dependent (BOLD) functional magnetic resonance imaging (fMRI) has been widely used to explore human brain function, questions remain regarding the ultimate spatial resolution of positive BOLD fMRI, and indeed the extent to which functional maps revealed by positive BOLD correlate spatially with maps obtained with other high-spatial-resolution mapping techniques commonly used in animals, such as optical imaging of intrinsic signal (OIS) and single-unit electrophysiology. Here, we demonstrate that the positive BOLD signal at 9.4T can reveal the fine topography of individual fingerpads in single-condition activation maps in nonhuman primates. These digit maps are similar to maps obtained from the same animal using intrinsic optical imaging. Furthermore, BOLD fMRI reliably resolved submillimeter spatial shifts in activation in area 3b previously identified with OIS (Chen et al., 2003) as neural correlates of the "funneling illusion." These data demonstrate that at high field, high-spatial-resolution topographic maps can be achieved using the positive BOLD signal, weakening previous notions regarding the spatial specificity of the positive BOLD signal.
