Does the Stimulus Type Influence Horses’ Performance in a Quantity Discrimination Task?
The ability to understand the relation between quantities has been documented in a wide range of species. Such quantity discrimination competences are commonly demonstrated by a choice of the larger quantity or numerosity ...
Representation of continuous hand and arm movements in macaque areas M1, F5, and AIP: a comparative decoding study.
OBJECTIVE: In the last decade, multiple brain areas have been investigated with respect to their decoding capability of continuous arm or hand movements. So far, these studies have mainly focused on motor or premotor areas ...
Immunogenicity of DNA Vaccines Encoding Simian Immunodeficiency Virus Antigen Targeted to Dendritic Cells in Rhesus Macaques
Targeting antigens encoded by DNA vaccines to dendritic cells (DCs) in the presence of adjuvants enhances their immunogenicity and efficacy in mice. To explore the immunogenicity of this approach in non-human primates, ...
Prenatal stress effects in a wild, long-lived primate: predictive adaptive responses in an unpredictable environment
Prenatal maternal stress affects offspring phenotype in numerous species including humans, but it is debated whether these effects are evolutionarily adaptive. Relating stress to adverse conditions, current explanations ...
Rhesus macaque IFITM3 gene polymorphisms and SIV infection
nterferon-induced transmembrane proteins (IFITMs) have been recognized as important antiviral effectors of the innate immune system, both in cell culture and in infected humans. In particular, polymorphisms of the human ...
Validation of a Fecal Glucocorticoid Assay to Assess Adrenocortical Activity in Meerkats Using Physiological and Biological Stimuli
In mammals, glucocorticoid (i.e. GC) levels have been associated with specific life-history stages and transitions, reproductive strategies, and a plethora of behaviors. Assessment of adrenocortical activity via measurement ...
Extrafoveal preview benefit during free-viewing visual search in the monkey.
Previous studies have shown that subjects require less time to process a stimulus at the fovea after a saccade if they have viewed the same stimulus in the periphery immediately prior to the saccade. This extrafoveal preview ...
Uniting functional network topology and oscillations in the fronto-parietal single unit network of behaving primates.
The functional communication of neurons in cortical networks underlies higher cognitive processes. Yet, little is known about the organization of the single neuron network or its relationship to the synchronization processes ...
Increased BST2 expression during simian immunodeficiency virus infection is not a determinant of disease progression in rhesus monkeys
Background: Bone marrow stromal cell antigen 2 (BST2), also known as tetherin, HM1.24 or CD317 represents a type 2 integral membrane protein, which has been described to restrict the production of some enveloped viruses by ...
Musculoskeletal representation of a large repertoire of hand grasping actions in primates.
Reach-to-grasp tasks have become popular paradigms for exploring the neural origin of hand and arm movements. This is typically investigated by correlating limb kinematic with electrophysiological signals from intracortical ...
