β2⁎ and β4⁎ nicotinic acetylcholine receptor expression changes with progressive parkinsonism in non-human primates

open access: yesNeurobiology of Disease, 2007
Autoradiography was used to investigate nicotinic acetylcholine receptor (nAChR) binding in the brains of two groups of macaque monkeys with parkinsonism produced by different types of MPTP exposure: animals with cognitive deficits but no motor symptoms (

Facial musculature in the rhesus macaque (Macaca mulatta): evolutionary and functional contexts with comparisons to chimpanzees and humans [PDF]

open access: yes, 2009
Facial expression is a common mode of visual communication in mammals but especially so in primates. Rhesus macaques (Macaca mulatta) have a well‐documented facial expression repertoire that is controlled by the facial/mimetic musculature as in all ...

Inter- and intra-specific gene-density-correlated radial chromosome territory arrangements are conserved in Old World monkeys [PDF]

open access: yes, 2005
Recently it has been shown that the gene-density correlated radial distribution of human 18 and 19 homologous chromosome territories (CTs) is conserved in higher primates in spite of chromosomal rearrangements that occurred during evolution.

Comparative chromosome band mapping in primates byin situ suppression hybridization of band specific DNA microlibraries [PDF]

open access: yes, 1991
A DNA-library established from microdissected bands 8q23 to 8q24.1 of normal human chromosomes 8 (Lüdecke et al., 1989) was used as a probe for chromosomal in situ suppression (CISS-) hybridization to metaphase chromosomes of man and primates including ...

The impact of cognitive testing on the welfare of group housed primates [PDF]

open access: yes, 2013
Providing cognitive challenges to zoo-housed animals may provide enriching effects and subsequently enhance their welfare. Primates may benefit most from such challenges as they often face complex problems in their natural environment and can be observed
