Fusion of quantitative susceptibility maps and T1-weighted images improve brain tissue contrast in primates Open
Recent progress in quantitative susceptibility mapping (QSM) has enabled the accurate delineation of submillimeter-scale subcortical brain structures in humans. However, the simultaneous visualization of cortical, subcortical, and white ma…

Spatial signatures of anesthesia-induced burst-suppression differ between primates and rodents Open
During deep anesthesia, the electroencephalographic (EEG) signal of the brain alternates between bursts of activity and periods of relative silence (suppressions). The origin of burst-suppression and its distribution across the brain remai…

Dynamic reconfiguration of macaque brain networks during natural vision Open
Natural vision engages a wide range of higher-level regions that integrate visual information over the large-scale brain network. How interareal connectivity reconfigures during the processing of ongoing natural visual scenes and how these…

Optogenetic stimulation of primate V1 reveals local laminar and large-scale cortical networks related to perceptual phosphenes Open
Developing optogenetics in non-human primates (NHPs) is essential for translating its successful implementation in rodents to clinical applications in humans. However, information about how optogenetics influences the primate cortex remain…

Dynamic reconfiguration of macaque brain networks during free-viewing of natural scenes Open
Natural vision involves the activation of a wide range of higher-level regions processing objects, motion, faces and actions. Here, we pursue a data-driven approach to explore how higher-level visual processes relate to the underlying stru…

Auditory representation of learned sound sequences in motor regions of the macaque brain Open
Human speech production requires the ability to couple motor actions with their auditory consequences. Nonhuman primates might not have speech because they lack this ability. To address this question, we trained macaques to perform an audi…

Auditory figure-ground analysis in rostral belt and parabelt of the macaque monkey Open
Segregating the key features of the natural world within crowded visual or sound scenes is a critical aspect of everyday perception. The neurobiological bases for auditory figure-ground segregation are poorly understood. We demonstrate tha…
