Analysis of Oocyte Quality in the Rhesus Macaque (Macaca mulatta)
… capacity of primate IVM oocytes using the rhesus macaque (Macaca mulatta) as a model. Research efforts included investigation of ovarian senescence, oocyte karyotype and spindle morphology, and establishment of an optimal sperm cryopreservation protocol for use in IVF. Histological examination of …

Functional and structural characterization of the macaque Middle face patch
… pathway of the Inferior Temporal lobe in the macaque brain. This region has been identified by functional MRI to respond preferentially to images of faces over non-face images, similar to functionally defined face selective regions in the human brain. In this thesis we spatially map the …

Construction of a Simian Immunodeficiency Virus Vaccine from Cynomolgus Macaque Cytomegalovirus
… a cytomegalovirus based vaccine in the rhesus macaque monkey model have protected close to half of all vaccinated monkeys from SIV, but questions remain as to the mechanism of protection and whether similar results will be seen in humans against HIV. These questions may be answerable through …

Oxygen Polarography in the Awake Macaque: Bridging BOLD fMRI and Electrophysiology
… polarographic recording system in the awake macaques as a surrogate for BOLD fMRI. Oxygen polarography measures tissue oxygen which is coupled to blood oxygen. This tool offers higher resolution than BOLD fMRI and can be more readily combined with electrophysiology.</p><p>Using this new tool …

The Impact Of Mitochondria On Preimplantation Development In The Rhesus Macaque
… the use of the NHP has established the rhesus macaque as an excellent research model for human reproduction due to the availability of normal, viable oocytes and embryos from fertile animals. Therefore, the overall goals of this study were to evaluate mitochondria in NHP oocytes and embryos and …

Developing improved challenge viruses for macaque models of HIV-1 infection
Infection of macaques with SIV/HIV chimeric viruses (SHIVs) is often used as a model of HIV-1 infection for pre-clinical vaccine studies. Although SHIV infection of macaques serves as the gatekeeper of promising vaccine candidates, it is limited by the fact there are a very small number of SHIVs …

Role of NMDA in the Visual Working Memory of the Macaque Monkey
… and 0.50-mg/kg IM) on the performance of macaque monkeys on a visual sequential comparison task, a task whose performance has minimal influence from other cognitive functions besides working memory. All monkeys showed a detrimental effect of ketamine administration on visual working memory …

Effects of Temporal and Spatial Context Within the Macaque Face-Processing System
… Anatomically distinct face patches in the macaque brain analyze facial form, and studies of the activity within these patches have begun to clarify the neural machinery that underlies facial perception. This system provides a uniquely valuable opportunity to study how context affects the …

A prefrontal source of visual target enhancement in the macaque area V4
… the effects of feature attention in the macaque visual area V4 by recording in V4 with and without muscimol inactivation in the VPA. We report here that neuronal activation in the VPA is necessary for firing rate increases related to target selection in V4. KEYWORDS: feature attention, …

Neural responses to relative motion in V1 and V2 of macaque monkeys
… single unit responses to relative motion in macaque VI and V2. We found that a substantial portion of V1 (62.2%) and V2 (70%) neurons respond to relative motion inputs. These neurons usually show V-shaped tuning curves to relative motion, with minimum response at zero relative motion. They …

Normalization Among Heterogeneous Population Confers Stimulus Discriminability on the Macaque Face Patch Neurons
… conducted electrophysiological recordings in the macaque temporal lobe, where bilateral face selective areas are tightly interconnected to form a hierarchical face processing stream. Assisted by functional MRI, these face patches could be targeted for single-cell recordings. For each neuron, the …

The Development of Social Behavior in the Tibetan Macaque (<i>Macaca thibetana</i>)
… social behavior in infant and juvenile Tibetan macaques (<em>Macaca thibetana</em>) at Mt. Huangshan, China, I made comparisons of these social behavioral frequencies across ages. I found consistent relationships between social behavioral frequencies, specifically grooming, bridging, and play …

Advances in MRI to probe the functional and structural network of the macaque brain
Diffusion MRI and fMRI have provided neuroscientists with non-invasive tools to probe the functional and structural network of the brain. Diffusion MRI is a neuroimaging technique capable of measuring the diffusion of water in neural tissue. It can reveal histological architecture irresolvable by …
