The paper shows wild chimpanzees increase social connectivity before risky group actions, forming broader but less dense affiliative networks.

This study uses MRI and computational methods to show that paramagnetic substances contribute to susceptibility anisotropy in primate brain tissue, alongside diamagnetic components.

The paper quantifies iron and neuromelanin in dopaminergic neurons across chimpanzee lifespan, finding stable iron-to-neuromelanin ratios and no evidence of saturation or increased toxicity with age.

The paper quantifies variation in primate social structures across 11 species, identifying distinct patterns in kin and rank biases and male-centered subgrouping.

This study documents the vocal sequence repertoire and rules of sooty mangabeys, revealing a previously unreported hierarchical system using only two call types.

This study compares motor cortex microstructure in humans and chimpanzees using qMRI, finding conserved high myelin and iron content in the hand-knob but enhanced rightward lateralization in humans.

This study presents the first spatial transcriptomic data from a chimpanzee brain, mapping gene expression and cell types in the frontal pole and integrating with single-nucleus transcriptomics to explore evolutionary differences.

This study identifies local genetic adaptation to habitat in wild chimpanzees, particularly to pathogens like malaria, using newly generated exomes.

This study maps chimpanzee brain development using MRI and histology, finding differences in myelination and iron accumulation compared to humans.

This study investigates the neuroinfectiology of Bcbva in wild chimpanzees, finding it causes meningitis and breaches the blood-brain barrier more effectively than B. anthracis.

This paper introduces HARSI, a new method for estimating fiber orientation distribution functions in fixed primate brains, showing it can capture complex fiber configurations comparable to HARDI.

The paper characterizes the genomic diversity of Treponema pallidum subsp. pertenue in non-human primates across sub-Saharan Africa, finding geographic clustering of strains rather than host or symptom-based clades.

This paper introduces a Multi-Echo dMRI method to improve SNR and reduce noise bias in post-mortem diffusion MRI, validated on a chimpanzee brain.

The paper introduces a consistency measure to assess social interaction predictability in sooty mangabeys and chimpanzees, finding aggression and dominance interactions are most consistent.
