PURPOSE/OBJECTIVES To establish initial reliability and validity of a Web-based survey focused on oncology advanced practice nurses' (APNs') knowledge, attitudes, and practice behaviors regarding advanced care planning, and to obtain preliminary understanding of APNs' knowledge, attitudes, and practice behaviors and perceived barriers to advanced care planning. DESIGN Descriptive, cross-secti...

Functional and evolutionary conservation of neural circuits of reward seeking >is a symbol of survival. It is found in most animals from insects to humans. Exploration is a component of a wide range of drug-elicited behaviors that reflects an appetitive motivational state when animals seek natural rewards such as food, water, and shelter for survival. Not only does the characterization of explo...

Making optimal choices in changing environments implies the ability to balance routine, exploitative patterns of behavior with novel, exploratory ones. We investigated whether galvanic vestibular stimulation (GVS) interferes with the balance between exploratory and exploitative behaviors in a free action selection task. Brief right-anodal and left-cathodal GVS or left-anodal and right-cathodal ...

BACKGROUND Accumulating evidence from epidemiological research has demonstrated an association between advanced paternal age and risk for several psychiatric disorders including autism, schizophrenia and early-onset bipolar disorder. In order to establish causality, this study used an animal model to investigate the effects of advanced paternal age on behavioural deficits in the offspring. ME...

the aim of the present research was to compare the performance evaluation indicators of club coaches from experts, athletes and coaches' viewpoints. the statistical population included all physical education experts of guilan province, heads, deputy heads and secretaries of physical education boards, athletes and coaches from rasht city (n=470) and 345 subjects (73.4%) participated in the ...

To investigate the role of Bone Morphogenic Protein Receptor Type II (BMPRII) in learning, memory, and exploratory behavior in mice, a tissue-specific knockout of BMPRII in the post-natal hippocampus and forebrain was generated. We found that BMPRII mutant mice had normal spatial learning and memory in the Morris water maze, but showed significantly reduced swimming speeds with increased floati...

In order to determine the distribution and function of the 5-HT5A serotonin receptor subtype, we generated knockout mice lacking the 5-HT5A gene. Comparative autoradiography studies of brains of wild-type (wt) and 5-HT5A knockout (5A-KO) mice revealed the existence of binding sites with high affinity for [125I]LSD that correspond to 5-HT5A receptors and that are concentrated in the olfactory bu...

Spontaneous recognition of a novel object is a popular measure of exploratory behavior, perception and recognition memory in rodent models. Because of its relative simplicity and speed of testing, the variety of stimuli that can be used, and its ecological validity across species, it is also an attractive task for comparative research. To date, variants of this test have been used with vertebra...

Genetically identical individuals display variability in their physiology, morphology, and behaviors, even when reared in essentially identical environments, but there is little mechanistic understanding of the basis of such variation. Here, we investigated whether Drosophila melanogaster displays individual-to-individual variation in locomotor behaviors. We developed a new high-throughout plat...

Although exploratory behaviors are ubiquitous in the animal kingdom, their computational underpinnings are still largely unknown. Behavioral Psychology has identified learning as a primary drive underlying many exploratory behaviors. Exploration is seen as a means for an animal to gather sensory data useful for reducing its ignorance about the environment. While related problems have been addre...
