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)
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 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)
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)
Pituitary adenomas (PAs) are neoplasms that may cause a variety of neurological and endocrine effects. Although known causal contributors include heredity, hormonal influence and somatic mutations, the pathophysiologic mechanisms driving tumorigenesis and invasion of sporadic PAs remain unknown. We hypothesized that alterations in DNA methylation are(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)
The Parachute® (Cardiokinetix, Inc., Menlo Park, California) is a catheter-based device intended to reverse left ventricular (LV) remodeling after antero-apical myocardial infarction. When deployed, the device partitions the LV into upper and lower chambers. To simulate its mechanical effects, we created a finite element LV model based on computed(More)
