Mirror Neurons in a New World Monkey, Common Marmoset [PDF]

open access: yesFrontiers in Neuroscience, 2015
Mirror neurons respond when executing a motor act and when observing others' similar act. So far, mirror neurons have been found only in macaques, humans, and songbirds. To investigate the degree of phylogenetic specialization of mirror neurons during the course of their evolution, we determined whether mirror neurons with similar properties to ...

Scanning electron microscopic study of the tongue in golden-headed lion tamarins, Leontopithecus chrysomelas (Callithrichidae: Primates)

open access: yesZoologia (Curitiba), 2009
Leontopithecus is the largest genus of Callithrichidae, occupying isolated remnants of the Atlantic Forest in Brazil. The objective of this study was to investigate the ultrastructure of the dorsum of the tongue of golden-headed lion tamarins. Tongues of

Social and environmental influences on the welfare of zoo-housed spider monkeys (Ateles geoffroyi rufiventris) [PDF]

open access: yes, 2009
The aim of this thesis was to provide a better understanding of the needs of spider monkeys (genus: Ateles) kept in zoological parks in order to provide an appropriate environment, which enhances the physical and emotional wellbeing of the individuals ...

A single mutation in the ACTR8 gene associated with lineage-specific expression in primates

open access: yesBMC Evolutionary Biology, 2020
Background Alternative splicing (AS) generates various transcripts from a single gene and thus plays a significant role in transcriptomic diversity and proteomic complexity.

Long-tailed macaques (Macaca fascicularis) can use simple heuristics but fail at drawing statistical inferences from populations to samples [PDF]

open access: yesRoyal Society Open Science, 2018
Human infants, apes and capuchin monkeys engage in intuitive statistics: they generate predictions from populations of objects to samples based on proportional information. This suggests that statistical reasoning might depend on some core knowledge that

Lice in Howler Monkeys and the Ancient Amaricas: Exploring the Potential Cost of Being Past Pets or Hunting Games

open access: yes, 2022
Sucking lice are highly host-specific ectoparasites, particularly on primates withmost lice species occurring only on a single species of host. Lice are found onprosimians, New World monkeys, Old World monkeys, and apes.

Cyto-, myelo- and chemoarchitecture of the prefrontal cortex of the Cebus monkey

open access: yesBMC Neuroscience, 2011
Background According to several lines of evidence, the great expansion observed in the primate prefrontal cortex (PfC) was accompanied by the emergence of new cortical areas during phylogenetic development.

Production and perception of situationally variable alarm calls in wild tufted capuchin monkeys (Cebus apella nigritus) [PDF]

open access: yes, 2010
Many mammalian and avian species produce conspicuous vocalizations upon encountering a predator, but vary their calling based on risk urgency and/or predator type.

New world, but not Old World, monkeys carry several genes encoding beta-microseminoprotein

open access: yes, 1999
It was shown by Southern hybridization that cotton-top tamarin and common marmoset, New World monkeys, carry three or more genes encoding beta-microseminoprotein, also known as PSP94.

Research Article Comparing covariance matrices: random skewers method compared to the common principal components model

open access: yesGenetics and Molecular Biology, 2007
Comparisons of covariance patterns are becoming more common as interest in the evolution of relationships between traits and in the evolutionary phenotypic diversification of clades have grown. We present parallel analyses of covariance matrix similarity
