Change Detection In Rhesus Monkeys and Humans
… of VWM. To this end, in the first aim, we tested monkeys and humans in virtually identical change detection tasks, where the subjects identified which memory item had changed between two displays. In addition to the typical manipulation of the number of items to-be-remembered (2-5 oriented bars), …

Change Detection Memory In Rhesus Monkeys and Humans
… about VSTM in non-human animals, including the rhesus monkey (<em>Macaca mulatta</em>). Given that rhesus monkeys are the premier medical model for humans, it is important to understand their VSTM if they are to contribute to understanding human memory. The primary goals of this study were to …

Reinforcement Learning and Economic Decision-making for Nutrient Rewards in Rhesus Monkeys
… and sensory qualities, I first demonstrated that monkeys consistently preferred fat and sugar to low-nutrient alternatives as if they assigned subjective values to the nutrient content. To identify the sensory basis of nutrient values, I developed engineering tools to measure food textures on …

Novel strategies for characterizing T Cell responses in SIV-infected rhesus monkeys
… Simian Immunodeficiency Virus (SIV) - infected rhesus monkey. While HIV research has focused on studying peripheral blood specimens, mucosal sites have recently been identified as a focal point for HIV replication and tissue destruction. They are usually the sites of primary infection in the …

The Effects of Low Intensity Ambient Lighting on Refractive Development in Rhesus Monkeys (Macacca mulatta)
… lighting levels cause myopias. METHODS: Infant rhesus monkeys (Macaca mulatta) were reared under reduced or “dim” ambient lighting (~50 lux) with either unrestricted vision or one of the monocular lens treatments that induces experimental anisometropias. The development of their refractive …

Social development and behavioural reciprocity in young rhesus monkeys with their siblings and non-siblings
… the development of social competence in immature monkeys. Social relationships between 28 sibling and non-sibling immature captive rhesus macaques, (Macaca mulatta), 4 to 40 months old, living in four social groups, were investigated. First, the characteristics of affiliative and agonistic aspects …

Neurobiological and Behavioral Phenotypes and Cocaine Self-Administration in Adult Rhesus Monkeys Exposed to Cocaine Throughout Gestation
Maternal cocaine addiction is a significant public health problem yet

An Investigation of the SHIV reservoirs in the lymphoid organs of HIV-vaccinated rhesus monkeys after SHIV challenge
… HIV vaccination and virus challenge using the rhesus macaque model. In addition, the study investigated the envelope sequences of the virus located in the potential reservoir sites in an attempt to understand viral variability. Cryopreserved peripheral blood mononuclear cells (PBMC) and cells …

Alterations of the Corticotropin Releasing Hormone Receptor System Following Early Life Stress and Ethanol Self-Administration in Rhesus Monkeys
… with nursery-reared (NR) and mother-reared rhesus monkeys induced to self-administer EtOH or control solution for over 12 months. Subjects underwent endocrine challenges to probe the HPA axis before and after drinking. Brains were processed for in vitro receptor autoradiography using [125I] …

Cocaine self-administration in rhesus monkeys: effects on neurobiology and cognition and evaluation of cognitive enhancement for addiction treatment
… deficits associated with cocaine use in monkeys, and examine cognitive enhancement as a pharmacotherapeutic approach to compliment behavioral methods.

DEVELOPMENT OF ALZHEIMER'S-LIKE PATHOLOGY IN NON-HUMAN PRIMATES WITH REDUCED LEVELS OF NOREPINEPHRINE
… of dopamine β-hydroxylase was detected in aged rhesus monkeys after DSP4. Distribution of amyloid identified by 6E10 was exacerbated in squirrel monkeys following DSP4 and elevated in aged rhesus monkeys after DSP4; additionally DSP4 increased the amyloid-β42 to amyloid-β40 ratio in aged rhesus …

EFFECTS OF SLEEP DISRUPTION AND QUETIAPINE ON COCAINE ABUSE: THE PATH TO DEVELOPMENT OF A MONKEY MODEL OF PTSD
… abuse. These studies used Old World macaques, rhesus monkeys, because of their close phylogeny to humans, their similar sleep-wake patterns and their cognitive abilities.

Low-frequency activity in the primate superior colliculus activates a head turning synergy: evidence using neck EMG recordings
… (EMG) activity of dorsal neck muscles from three rhesus monkeys performing a gap-saccade paradigm with different levels of reward expectancy. As reward expectancy increased, low-frequency dSC activity increased and EMG activity from the contralateral obliquus capitis inferior (OCI) muscle also …

Neural basis of multi-attribute economic value: examples from humans and monkeys
… and (2) probability-magnitude liquid reward in rhesus monkeys using single-cell electrophysiology. In the first experiment, human participants were asked to make choices between two bundle reward options, which each contain two milkshakes. The participants were scanned with fMRI to study how the …

Role of the precentral cortex in adapting behavior to different mechanical environments
… we recorded precentral neural activity in rhesus monkeys that were trained to perform visually-cued reaching movements while holding on to a robotic manipulandum capable of changing the forces experienced during the task. Preparation and control of the reaching movements were correlated …
