Primatology in the Neurosciences II

Published: September 24, 2013

Edited by: Donald C. Dunbar

Non-human primate studies continue to grow in the neurosciences because these animals are genetically, anatomically, physiologically, and behaviorally similar to humans. Articles published in the American Journal of Primatology (AJP) use primates as either animal models or as evolving entities to be studied in their own right. Both uses are critical to the advancement of primate neuroscience research. The 12 articles published in the first virtual issue of "Primatology in the Neurosciences" represented the majority of studies on primate neuroscience that appeared in the AJP over a five-year period (2006-2010). By contrast, this second issue contains 16 representative articles selected from nearly 40 contributions published over a three-year period (2011-2013). This rapid rise in the number of neuroscience articles can be largely attributed to the rapid growth of interest in this field among the AJP readership, and in the ever increasing number of neuroscientists who consider the AJP as a viable outlet for their research endeavors. The AJP strongly encourages this trend to continue.

Primatology in Latin America

Published: July 10, 2013

Edited by: Paul A. Garber

New World primates represent an extremely successful radiation of small, moderate, and larger bodied monkeys characterized by high taxonomic and evolutionary diversity. Many countries in Latin America have developed an outstanding set of primatologists, geneticists, conservationists, biologists, ecologists and botanists to promote the study and management of primate populations and tropical forests. In addition, Latin American scientists have made major breakthroughs in advancing our knowledge of primate behavior, ecology, and evolution, and have frequently published their research in the American Journal of Primatology. AJP is the highest ranked primate journal, with an Impact Factor in 2012 of 2.459. Below is a virtual issue of AJP to highlight the diversity of research we have published by Latin American scholars during the past few years. We encourage you to continue to send the results of your research for review and publication in the American Journal of Primatology.

Primatology in the Neurosciences

Published: 28 Oct 2010

Edited By: Donald Dunbar, Editor

Non-human primate studies, particularly clinical and translational, are increasing in the neurosciences. Their genetic, anatomic, physiologic, and behavioral similarities to humans make primates critical research models. The American Journal of Primatology (AJP) is an important forum because it publishes both traditional neuroscience papers using the primate model, and papers that place primate biology and behavior in the environmental context in which the animals have evolved. The deeper understanding gained from these latter studies will clarify interpretation, and the advantages and disadvantages of using particular species as research models, thereby increasing the relevance and impact of neuroscience research. This virtual AJP issue contains a selection of recent articles that exemplifies the range of topics that are relevant to the neurosciences.
