U.S. primate researchers say they've used prairie voles as models in understanding early life parent-offspring nurturing impacts on later life relationships. Yerkes National Primate Research Center scientists at Emory University said by influencing early social experience in prairie voles, they have gained greater insight into what aspects of early social experience drive diversity in adult social behavior. Prairie voles are small, highly social, hamster-sized rodents that often form stable,...

Researchers at the Yerkes National Primate Research Center, Emory University, have demonstrated that prairie voles may be a useful model in understanding the neurochemistry of social behavior. By influencing early social experience in prairie voles, researchers hope to gain greater insight into what aspects of early social experience drive diversity in adult social behavior. The study is currently available online in a special edition of Frontiers in Behavioral Neuroscience that is focused on...

Researchers at Yerkes National Primate Research Center, Emory University, contributed key comparative data for a landmark study showing African wild chimpanzees infected with simian immunodeficiency virus (SIV), an HIV-1-like virus, die prematurely and develop hallmarks of HIV-1 infection and AIDS.This surprising discovery by scientists at the University of Alabama at Birmingham (UAB), and reported in the July 23 issue of Nature, alters the current view of AIDS virus infections in African...

Researchers at the Yerkes National Primate Research Center, Emory University, have demonstrated for the first time rhesus monkeys and humans share a specific perceptual mechanism, configural perception, for discriminating among the numerous faces they encounter daily. The study, reported in the June 25 online issue of Current Biology, provides insight into the evolution of the critical human social skill of facial recognition, which enables us to form relationships and interact appropriately...

Researchers at the Yerkes National Primate Research Center, Emory University, developed a test in nonhuman primates that is now using infrared eye tracking to detect mild cognitive impairment (MCI) in humans. The researchers hope the advanced technology will be helpful in predicting the onset of Alzheimer's disease. The test, which is featured in the current online issue of The American Journal of Alzheimer's Disease and Other Dementias, is helping researchers further understand the role of...

According to Bianca Acevedo, a New York neuroscientist, love is in the head and not the heart. Acevedo is part a new field in science that seeks to biologically explain love, and so far they have found that love is mostly understood through hormones, genetics, and brain images, according to a report from the Associated Press. "It has a biological basis. We know some of the key players," said Larry Young of the Yerkes National Primate Research Center, where he searches for clues as to what...

Having trouble with your marriage? Take a pill!  Believe it or not, this could happen, says the researcher who is examining the chemical composition of love.Larry Young states that his ultimate goal is not a love potion but hopes to find information on conditions like autism, which limits the natural ability to create social attachments, by investigating brain chemicals connected to emotional attachment."Biologists may soon be able to reduce certain mental states associated with love to...

Chimpanzees recognize their pals by using some of the same brain regions that switch on when humans register a familiar face, according to a report published online on December 18th in Current Biology, a Cell Press publication. The study "” the first to examine brain activity in chimpanzees after they attempt to match fellow chimps' faces "” offers new insight into the origin of face recognition in humans, the researchers said. "We can learn about human origins by studying our...

In the first study of its kind, researchers at the Yerkes National Primate Research Center and Emory Vaccine Center, Emory University, have developed a multidisciplinary approach involving immunology, genomics and bioinformatics to predict the immunity of a vaccine without exposing individuals to infection. This approach addresses a long-standing challenge in the development of vaccines--that of only being able to determine immunity or effectiveness long after vaccination and, often, only...

Scientists at Emory University have genetically engineered monkeys to have Huntington's disease in hopes of gaining a better understanding of the fatal, hereditary ailment to develop possible new treatments.The researchers, from Emory University's Yerkes National Primate Research Center in Atlanta, said the monkeys are the first primates to be genetically modified. Describing their work, they said one of two surviving rhesus macaque monkeys engineered to have the defective gene that causes...
