Estradiol increases female sexual initiation independent of male responsiveness in rhesus monkeys.
Copulation and female initiation of sexual behavior vary across the ovarian cycle, suggesting that female hormonal condition influences female sexual motivation in rhesus monkeys. However, the effects of hormones on female sexual motivation are difficult to identify because male behavior also varies with female hormonal condition. During the nonbreeding season, male rhesus monkeys are sexually ...
متن کاملAnnual changes in the sexual potency of captive male rhesus monkeys.
Like many non-primate mammals, several non-human primates have wellmarked mating and birth seasons (Lancaster & Lee, 1965; Michael & Zumpe, 1971). In a relatively controlled laboratory environment, Michael & Keverne (1971) found that intact rhesus males paired with intact females, whose oviducts had been ligated to prevent pregnancy, showed a peak in ejaculatory activity in December followed by...

چکیده هدف اصلی از طراحی لرزه ای تامین ایمنی جانی در هنگام وقوع زلزله و تعمیر پذیر بودن سازه خسارت دیده، پس از وقوع زلزله است. تجربه زلزله های اخیر نشان داده است که ساختمان های طراحی شده با آیین نامه های مبتنی بر نیرو از نظر محدود نمودن خسارت وارده بر سازه دقت لازم را ندارند. این امر سبب پیدایش نسل جدید آیین نامه های مبتنی بر عملکرد شده است. در این آیین نامه ها بر اساس تغییرشکل های غیرارتجاعی ...
15 صفحه اولGeneration of Chimeric Rhesus Monkeys
Totipotent cells in early embryos are progenitors of all stem cells and are capable of developing into a whole organism, including extraembryonic tissues such as placenta. Pluripotent cells in the inner cell mass (ICM) are the descendants of totipotent cells and can differentiate into any cell type of a body except extraembryonic tissues. The ability to contribute to chimeric animals upon reint...
متن کاملSelf-agency in rhesus monkeys.
Rhesus monkeys (Macaca mulatta) have shown the ability to monitor their own mental states, but fail the mirror self-recognition test. In humans, the sense of self-agency is closely related to self-awareness, and results from monitoring the relationship between intentional, sensorimotor and perceptual information. Humans and rhesus monkeys were trained to move a computer icon with a joystick whi...
