Expression of calcium-binding proteins and selected neuropeptides in the human, chimpanzee, and crab-eating macaque claustrum

Frontiers in Systems Neuroscience, 2014
The claustrum is present in all mammalian species examined so far and its morphology, chemoarchitecture, physiology, phylogenesis and ontogenesis are still a matter of debate.

Environmental variability supports chimpanzee behavioural diversity

Nature Communications, 2020
Large brains and behavioural innovation are positively correlated, species-specific traits, associated with the behavioural flexibility animals need for adapting to seasonal and unpredictable habitats.

Staring death in the face: chimpanzees' attention towards conspecific skulls and the implications of a face module guiding their behaviour

Royal Society Open Science, 2022
Chimpanzees exhibit a variety of behaviours surrounding their dead, although much less is known about how they respond towards conspecific skeletons. We tested chimpanzees' visual attention to images of conspecific and non-conspecific stimuli (cat/chimp ...

Vaccinating captive chimpanzees to save wild chimpanzees [PDF]

Proceedings of the National Academy of Sciences, 2014
Significance Although infectious disease is now recognized as a major threat to wild gorillas and chimpanzees, safety fears have stifled the use of a powerful disease control tool, vaccination. To illustrate that safety can be rigorously evaluated before vaccines are used on wild apes, we conducted what is, to our knowledge, the first ...

Differences between human and chimpanzee genomes and their implications in gene expression, protein functions and biochemical properties of the two species

BMC Genomics, 2020
Chimpanzees are the closest living relatives of humans. The divergence between human and chimpanzee ancestors dates to approximately 6,5–7,5 million years ago.

Chimpanzee (Pan troglodytes) gaze is conspicuous at ecologically-relevant distances

Scientific Reports, 2022
Chimpanzee (Pan troglodytes) sclera appear much darker than the white sclera of human eyes, to such a degree that the direction of chimpanzee gaze may be concealed from conspecifics.

A comprehensive atlas of white matter tracts in the chimpanzee

bioRxiv, 2020
Chimpanzees (Pan troglodytes) are, along with bonobos, humans’ closest living relatives. The advent of diffusion MRI tractography in recent years has allowed a resurgence of comparative neuroanatomical studies in humans and other primate species. Here we

Medium-sized and large bodied mammals of Marshall Wetlands, a proposed protected area in Liberia [PDF]

Check List
Liberia comprises 43% of the upper Guinean tropical forest of West Africa, a global hotspot with high levels of biodiversity and endemism succumbing to accelerated rates of deforestation.

Modeling of early neural development in vitro by direct neurosphere formation culture of chimpanzee induced pluripotent stem cells

Stem Cell Research, 2020
Evolutionary developmental biology of our closest living relative, the chimpanzee (Pan troglodytes), is essential for understanding the origin of human traits.

Comparison of induced neurons reveals slower structural and functional maturation in humans than in apes

eLife, 2021
We generated induced excitatory neurons (iNeurons, iNs) from chimpanzee, bonobo, and human stem cells by expressing the transcription factor neurogenin-2 (NGN2).
