Voter choice is one of the most important problems in political science. The most common models assume that voting is a rational choice based on policy positions (e.g., key issues) and nonpolicy information (e.g., social identity, personality). Though such models explain macroscopic features of elections, they also reveal important anomalies that have been resistant to explanation. We argue for a new approach that builds upon recent research in cognitive science and neuroscience; specifically, we contend that policy positions and social identities do not combine in merely an additive manner, but compete to determine voter preferences...

Major advances in behavioral neuroscience have been facilitated by the development of consistent and highly reproducible experimental paradigms that have been widely adopted. In contrast, many different experimental approaches have been employed to expose laboratory mice and rats to acute versus chronic intermittent stress. An argument is advanced in this review that more consistent approaches to the design of chronic intermittent stress experiments would provide greater reproducibility of results across laboratories and greater reliability relating to various neural, endocrine, immune, genetic, and behavioral adaptations...

RATIONALE: Program evaluation is essential to help determine the success of an evidence-based practice program and assist with translating these processes across settings. AIMS: The purpose of this study was to evaluate the usefulness of 2 competency programs that sought to improve neurocritical care nurses' knowledge of and adherence to evidence-based stroke and spinal cord injury guidelines. These programs consisted of 3 specific implementation strategies, including local opinion leaders, printed educational materials, and educational outreach...

Consciousness is often said to disappear in deep, dreamless sleep. We argue that this assumption is oversimplified. Unless dreamless sleep is defined as unconscious from the outset there are good empirical and theoretical reasons for saying that a range of different types of sleep experience, some of which are distinct from dreaming, can occur in all stages of sleep. We introduce a novel taxonomy for describing different kinds of dreamless sleep experiences and suggest research methods for their investigation...

BACKGROUND: Patients with severe acute brain injury (SABI) raise important palliative care considerations associated with sudden devastating injury and uncertain prognosis. OBJECTIVE: The goal of this study was to explore how family members, nurses, and physicians experience the palliative and supportive care needs of patients with SABI receiving care in the neuroscience intensive care unit (neuro-ICU). DESIGN: Semistructured interviews were audiotaped, transcribed, and analyzed using thematic analysis...

OBJECTIVE: Behavioral neuroscience studies in freely moving rodents require small, light-weight implants to facilitate neural recording and stimulation. Our goal was to develop an integrated package of 3D printed parts and assembly aids for labs to rapidly fabricate, with minimal training, an implant that combines individually positionable microelectrodes, an optical fiber, zero insertion force (ZIF-clip) headstage connection, and secondary recording electrodes, e.g. for electromyography (EMG)...

Astrocytic excitability relies on cytosolic calcium increases as a key mechanism, whereby astrocytes contribute to synaptic transmission and hence learning and memory. While it is a cornerstone of neurosciences that experiences are remembered, because transmitters activate gene expression in neurons, long-term adaptive astrocyte plasticity has not been described. Here, we investigated whether the transcription factor CREB mediates adaptive plasticity-like phenomena in astrocytes. We found that activation of CREB-dependent transcription reduced the calcium responses induced by ATP, noradrenaline, or endothelin-1...

BACKGROUND: Team-based care has been shown to offer more comprehensive benefits to patients when compared to standard physician-based care alone in clinics for chronic conditions. However, apart from grant-funded multidisciplinary clinics, there are no reports on the usage of same-day physical therapy (PT) consults within a daily outpatient neuromuscular disease (NMD) physician clinic. OBJECTIVE: To determine the impact of same-day PT consults at the University of Utah's outpatient Clinical Neurosciences Center...

Antipsychotic drugs, all of which block the dopamine D2 receptor to a greater or lesser extent, are the mainstay for the pharmacological treatment of schizophrenia. Engaging in a deeper understanding of how antipsychotics act on the brain and body, at the cellular, molecular and physiological level is vital to comprehend both the beneficial and potentially harmful actions of these medications and stimulate development of novel therapeutics. To address this, we review recent advances in our understanding of neuroadaptations to antipsychotics, focusing on (1) treatment efficacy, (2) impact on brain volume and (3) evidence from human post-mortem studies that attempt to dissect neuropathological effects of antipsychotic drugs from organic schizophrenia neurobiology and (4) cardio-metabolic side effects...

To assess the primary metabolite of norepinephrine, 3,4-dihydroxyphenylglycol (DHPG), as a sensitive biomarker for norepinephrine transporter (NET) function and the relationship of DHPG measured peripherally and centrally, NET was antagonized with 80 mg/d atomoxetine for 18 days. Twelve healthy subjects were treated with atomoxetine in an open-label, multiple-dose exploratory study. Plasma atomoxetine reached steady state by day 6, and the pharmacokinetic results demonstrated availability of atomoxetine to the central nervous system...

The last 40 years have seen a remarkable increase in the teaching of neuroscience at the undergraduate level. From its origins as a component of anatomy or physiology departments to its current status as an independent interdisciplinary field, neuroscience has become the chosen field of study for many undergraduate students, particularly for those interested in medical school or graduate school in neuroscience or related fields. We examined how life science-based neuroscience education is offered at large public universities in the Western United States...

Mind-brain dualism has dominated historical commentary on dystonia, a dichotomous approach that has left our conceptual grasp of it stubbornly incomplete. This is particularly true of functional dystonia, most diagnostically challenging of all functional movement disorders, in which the question of inherent psychogenicity remains a focus of debate. Phenomenological signs considered in isolation lack the specificity to distinguish organic and nonorganic forms, and dystonia's variability has frustrated attempts to develop objective laboratory-supported standards...

Hallucinations are at the core of the diagnosis of schizophrenia and schizoaffective disorders, and many neuroscience studies focus on hallucinations. However, there is a lack of data on prevalence, subtyping, and clinical correlates of hallucinations as well as on the comparison of hallucinating schizophrenia versus hallucinating schizoaffective patients. Analysis of all psychopathology evaluations is based on the AMDP scale in a German psychiatric university hospital between 2007 and 2013 regarding patients with schizophrenia or schizoaffective disorder (diagnosed according to ICD-10)...

Numerous honorary initiatives for humanitarian aid towards refugees illustrate the high prevalence of altruistic behavior in the population. In medicine, an exquisite example of a human propensity for altruism is organ donation. Current perspectives on the neurobiology of altruism suggest that it is deeply rooted in the motivational architecture of the social brain. This is reflected by the social evolution of cooperation and parochialism, both of which are modulated by the evolutionarily conserved peptide hormone oxytocin...

BACKGROUND: Seizures can lead to cardiac arrhythmias by a number of mechanisms including activation/inhibition of cortical autonomic centers, increase in vagal tone through activation of brainstem reflex centers, and respiratory failure. Ictal asystole (IA) is a potential mechanism underlying sudden unexpected death in epilepsy (SUDEP). We analyzed the clinical features of 5 patients who developed IA requiring pacemaker implantation. METHODS: Patients with ictal arrhythmias were identified from the video-telemetry and ambulatory EEG database at Greater Manchester Neurosciences Centre, as well as an independent epilepsy residential care facility...
