Development of a 24-Channel 3T Phased-Array Coil for fMRI in Awake Monkeys - Mitigating Spatiotemporal Artifacts in Ferumoxytol-Weighted Functional Connectivity Estimation

This paper develops a 24-channel 3T RF coil for fMRI in awake monkeys, improving ferumoxytol-weighted functional connectivity estimation and identifying human-like functional networks.

Charting Cortical-Layer Specific Area Boundaries Using Gibbs Ringing Attenuated T1w/T2w-FLAIR Myelin MRI

This paper introduces a method to map cortical-layer specific area boundaries in primates using myelin MRI, revealing a 182 area/subarea partition in macaques with high homology to human myelin maps.

Linking neuron-axon-synapse architecture to white matter vasculature using high-resolution multimodal MRI in primate brain

This study links neuron-axon-synapse architecture to white matter vasculature in primates using multimodal MRI and other techniques, finding correlations between vascular patterns and axonal features.

Mapping vascular network architecture in primate brain using ferumoxytol-weighted laminar MRI

This study maps vascular networks in primate brains using ferumoxytol-weighted MRI, revealing regional variations in vascular volume and its relationship with neuronal and receptor densities.

Empirical Transmit Field Bias Correction of T1w/T2w Myelin Maps

This paper introduces two empirical methods to correct B1+ transmit field biases in T1w/T2w myelin maps, improving their accuracy for neuroanatomical and statistical analyses.

Retinotopic organization of feedback projections in primate early visual cortex: implications for active vision

The paper investigates feedback projections in primate early visual cortex, revealing retinotopic organization and differences in connection strength between ventral and dorsal stream areas.

Anatomical variability, multi-modal coordinate systems, and precision targeting in the marmoset brain

This paper develops a non-invasive multi-modal neuroimaging pipeline for precise brain targeting in marmosets, revealing significant intersubject variability and creating new population-based templates.

Brain/MINDS Beyond Human Brain MRI Study: Multi-Site Harmonization for Brain Disorders Throughout the Lifespan

This paper outlines a multi-site MRI study aiming to establish harmonized imaging biomarkers for brain disorders across the lifespan using standardized protocols and data from healthy and patient subjects.

Towards HCP-Style Macaque Connectomes: 24-Channel 3T Multi-Array Coil, MRI Sequences and Preprocessing

The paper develops a 24-channel MRI coil and adapts HCP protocols for macaques, enabling high-quality in vivo imaging and preprocessing comparable to human studies.

Diffusion Tensor Model links to Neurite Orientation Dispersion and Density Imaging at high b-value in Cerebral Cortical Gray Matter

The paper shows that high b-value diffusion tensor imaging (DTI) metrics are strongly associated with NODDI metrics in cortical gray matter, but low b-value DTI does not accurately reflect microstructure.
