A choice that reliably produces a preferred outcome can be automated to liberate cognitive resources for other tasks. Should an outcome become less desirable, behavior must adapt in parallel or it becomes perseverative. Corticostriatal systems are known to mediate choice learning and flexibility, but the molecular mechanisms of these processes are not well(More)
This paper presents a novel experiment on group conflict. Subjects are divided into groups according to preferences on paintings, and subjects are divided into groups according to self-declared political affiliations and leanings. Using a unique within subject design, we find twenty percent of subjects destroy social welfare – at personal cost – when facing(More)
BACKGROUND Pituitary adenomas (PAs) are commonly occurring neoplasms with diverse endocrine and neurological effects. Although somatic gene mutations are uncommon in sporadic PAs, recent studies lend support to epigenetic modification as a potential cause of tumorigenesis and tumor progression. METHODS A systematic literature review of the PubMed and(More)
OBJECT A more comprehensive understanding of the epigenetic abnormalities associated with meningioma tumorigenesis, growth, and invasion may provide useful targets for molecular classification and development of targeted therapies for meningiomas. METHODS The authors performed a review of the current literature to identify the epigenetic modifications(More)
Background Oculorrhea, or cerebrospinal fluid leakage developing from a cranio-orbital fistula, is a rare development following traumatic injury. Case Report A 22-year-old man involved in a motor vehicle accident developed a blowout fracture of the left orbital roof penetrating the frontal lobe, inducing oculorrhea. He underwent a supraorbital craniotomy(More)
This paper presents a novel experiment on identity and individual social preferences. Using a within subject design and new empirical methods, we find more than twenty percent of subjects destroy total income – at personal cost – to earn more than subjects outside their group. Minimal groups divide subjects according to arbitrary criteria, and political(More)
INTRODUCTION A single-center study to define the sensitivity and specificity of intraoperative neurophysiological monitoring in detecting new neurological deficits. METHODS A cohort of 4989 consecutive (2962 male and 2027 female) patients operated on over 3 years was evaluated. Subgroup analysis was performed for patients undergoing posterior cervical(More)
This paper reveals that a subset of subjects adopting extreme behavior underlies intergroup bias. In a simple task, we replicate previous results that, on average, subjects are less inequity averse allocating income to out-group members. Using a within subject design and new econometric techniques, however, we find a group division does not matter for most(More)
This paper deconstructs social preferences in group contexts and resolves the contradiction between laboratory findings of inequity aversion and the destructive reality of group conflict. The paper replicates previous results that subjects are—on average—inequity averse towards out-group participants and more so towards in-group. However, the mean is not(More)
BACKGROUND Hospital-acquired conditions (HACs) are defined by the Centers for Medicaid and Medicare Services (CMS) as preventable adverse events that do not qualify for reimbursement of resulting hospital costs. HACs have been employed as a metric for quality of patient care. Patients undergoing cervical spine fusions are at risk for occurrence of HACs(More)
