Conceptual metaphorical mapping in chimpanzees (Pan troglodytes)

eLife, 2013
Conceptual metaphors are linguistic constructions. Such a metaphor is humans’ mental representation of social rank as a pyramidal-like structure. High-ranked individuals are represented in higher positions than low-ranked individuals. We show that conceptual metaphorical mapping between social rank and the representational domain exists in our closest ...

Development of Emotional Expressions in Chimpanzees (Pan troglodytes) [PDF]

Annals of the New York Academy of Sciences, 2003
Chimpanzee infants, like human infants, exhibit some emotional expressions in the first days of life, and additional expressions develop over the first months of life. We know relatively little about the influence of the rearing environment on the development of emotional expression in chimpanzees (or in human infants).

Covariación ontogénica en el endocráneo de Pan troglodytes / Ontogenetic covariation in the endocranium of Pan troglodytes

Revista Argentina de Antropología Biológica, 2014
RESUMEN Diversos estudios proponen que el neurocráneo en Homo sapiens es una estructura integrada y que la morfología de la bóveda y la base se asocia con modificaciones del cerebro. En este estudio se evaluó la covariación ontogénica en el endocráneo de Pan troglodytes, otro primate altamente encefalizado.

Chimpanzee (Pan troglodytes) gaze is conspicuous at ecologically-relevant distances. [PDF]

Sci Rep, 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.

Combinatorics and complexity of chimpanzee (Pan troglodytes) facial signals. [PDF]

Anim Cogn
There have been shifts toward more systematic and standardized methods for studying non-human primate facial signals, thanks to advancements like animalFACS.

Body part categorical matching in chimpanzees (Pan troglodytes). [PDF]

Sci Rep
Humans categorize body parts, reflecting our knowledge about bodies, and this could be useful in higher-level activities involving bodies. We tested whether humans’ closest living relatives—chimpanzees—have the same ability using touchscreen tasks ...

Chimpanzees (<i>Pan troglodytes</i>) Indicate Mammalian Abundance Across Broad Spatial Scales. [PDF]

Ecol Evol
Ongoing ecosystem change and biodiversity decline across the Afrotropics call for tools to monitor the state of biodiversity or ecosystem elements across extensive spatial and temporal scales.

Autism and mild epilepsy associated with a de novo missense pathogenic variant in the GTPase effector domain of DNM1

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView., 2023
Abstract Dynamin 1 is a GTPase protein involved in synaptic vesicle fission, which facilitates the exocytosis of neurotransmitters necessary for normal signaling. Pathogenic variants in the DNM1 gene are associated with intractable epilepsy, often manifested as infantile spasms at onset, developmental delay, and a movement disorder, and are located in ...

Towards the restoration of ancient hominid craniofacial anatomy: Chimpanzee morphology reveals covariation between craniometrics and facial soft tissue thickness.

PLoS ONE, 2021
In modern humans, facial soft tissue thicknesses have been shown to covary with craniometric dimensions. However, to date it has not been confirmed whether these relationships are shared with non-human apes.

Age, adrenal steroids, and cognitive functioning in captive chimpanzees (Pan troglodytes). [PDF]

PeerJ, 2022
Background Dehydroepiandrosterone-sulfate is the most abundant circulating androgen in humans and other catarrhines. It is involved in several biological functions, such as testosterone production, glucocorticoid antagonist actions, neurogenesis and ...
