Measuring Smoking-Related Preoccupation and Compulsive Drive: Evaluation of the Obsessive Compulsive Smoking Scale
(Springer-Verlag, 2010-6-26)RATIONALE. Tobacco use for many people is compulsive in nature. Compelling theories of how smoking becomes compulsive exist but are largely based on extrapolation from neuroscience findings. Research on smokers is impeded, ... -
Patterns of Prefrontal Dysfunction in Alcoholics with and without Korsakoff's Syndrome, Patients with Parkinson's Disease, and Patients with Rupture and Repair of the Anterior Communicating Artery
(Dove Medical Press, 2006)This study compared patterns of frontal-lobe dysfunction in alcoholics with Korsakoff's syndrome (KS: n = 9), non-Korsakoff alcoholics (AL: n = 28), patients with Parkinson's disease (PD: n = 18), and patients with rupture ... -
Genetic Influences on Attention Deficit Hyperactivity Disorder Symptoms from Age 2 to 3: A Quantitative and Molecular Genetic Investigation
(BioMed Central, 2010-12-1)BACKGROUND. A twin study design was used to assess the degree to which additive genetic variance influences ADHD symptom scores across two ages during infancy. A further objective in the study was to observe whether genetic ... -
Complementary Roles of Hippocampus and Medial Entorhinal Cortex in Episodic Memory
(Hindawi Publishing Corporation, 2008-7-6)Spatial mapping and navigation are figured prominently in the extant literature that describes hippocampal function. The medial entorhinal cortex is likewise attracting increasing interest, insofar as evidence accumulates ... -
Evaluation of the Oscillatory Interference Model of Grid Cell Firing through Analysis and Measured Period Variance of Some Biological Oscillators
(Public Library of Science, 2009-11-20)Models of the hexagonally arrayed spatial activity pattern of grid cell firing in the literature generally fall into two main categories: continuous attractor models or oscillatory interference models. Burak and Fiete ... -
Attending to Emotional Cues for Drug Abuse: Bridging the Gap Between Clinic and Home Behaviors
(National Institute on Drug Abuse, 2007-04)Classical conditioning models of addiction provide keys to understanding the vexing discrepancy between substance abuse patients' desire to abstain when they are in therapy sessions and their tendency to relapse. Experiments ... -
The Impact of Clinical and Cognitive Variables on Social Functioning in Parkinson's Disease: Patient versus Examiner Estimates
(SAGE-Hindawi Access to Research, 2010-3-11)Purpose. To assess the impact of clinical variables on social skills and behaviors in Parkinson's disease (PD) patients and patient versus examiner estimates of social functioning. Methods. Twenty-eight patients with PD ... -
Validity and Reliability of a Fijian Translation and Adaptation of the Eating Disorder Examination Questionnaire
(Wiley Subscription Services, Inc., A Wiley Company, 2009-3-23)OBJECTIVE: Assessment of disordered eating has uncertain validity across culturally diverse populations. This study evaluated Eating Disorder Examination Questionnaire (EDE-Q) performance in an ethnic Fijian study population. ... -
Adaptation and Evaluation of the Clinical Impairment Assessment to Assess Disordered Eating Related Distress in an Adolescent Female Ethnic Fijian Population
(Wiley Subscription Services, Inc., A Wiley Company, 2009-03-23)OBJECTIVE: Measurement of disease-related impairment and distress is central to diagnostic, therapeutic, and health policy considerations for eating disorders across diverse populations. This study evaluates psychometric ... -
Cognitive-Behavior Therapy (CBT) for Panic Disorder: Relationship of Anxiety and Depression Comorbidity with Treatment Outcome
(Springer US, 2009-7-24)Research evaluating the relationship of comorbidity to treatment outcome for panic disorder has produced mixed results. The current study examined the relationship of comorbid depression and anxiety to treatment outcome ... -
Perceptual Learning of Motion Leads to Faster Flicker Perception
(Public Library of Science, 2006-12-20)Critical flicker fusion thresholds (CFFT) describe when quick amplitude modulations of a light source become undetectable as the frequency of the modulation increases. The threshold at which CFF occurs has been shown to ... -
Is Task-Irrelevant Learning Really Task-Irrelevant?
(Public Library of Science, 2008-11-24)In the present study we address the question of whether the learning of task-irrelevant stimuli found in the paradigm of task-irrelevant learning (TIPL) [1]-[9] is truly task irrelevant. To test the hypothesis that ... -
Benefits of Stimulus Congruency for Multisensory Facilitation of Visual Learning
(Public Library of Science, 2008-1-30)BACKGROUND. Studies of perceptual learning have largely focused on unisensory stimuli. However, multisensory interactions are ubiquitous in perception, even at early processing stages, and thus can potentially play a role ... -
Genetic and Environmental Influences on Cortisol Regulation Across Days and Contexts in Middle-Aged Men
(Springer US, 2010-3-18)Cortisol is an indicator of hypothalamic–pituitary–adrenal axis responsivity to stress, but few twin studies have examined the heritability of cortisol concentrations in adults across the diurnal cycle and in different ... -
Linking Cellular Mechanisms to Behavior: Entorhinal Persistent Spiking and Membrane Potential Oscillations May Underlie Path Integration, Grid Cell Firing, and Episodic Memory
(Hindawi Publishing Corporation, 2008-7-21)The entorhinal cortex plays an important role in spatial memory and episodic memory functions. These functions may result from cellular mechanisms for integration of the afferent input to entorhinal cortex. This article ... -
Working Memory Performance Correlates with Prefrontal-Hippocampal Theta Interactions but not with Prefrontal Neuron Firing Rates
(Frontiers Research Foundation, 2010-03-10)Performance of memory tasks is impaired by lesions to either the medial prefrontal cortex (mPFC) or the hippocampus (HPC); although how these two areas contribute to successful performance is not well understood. mPFC unit ... -
Sources of the Spatial Code Within the Hippocampus
(Biology Reports Ltd, 2009-01-21)Neurons in the hippocampus are thought to provide information on an animal's location within its environment. Input to the hippocampus comes via afferents from the entorhinal cortex, which are separated into several major ... -
Hippocampal Cell Assemblies: Time Encoding Neurons or Goal Representations?

Greater Pre-Stimulus Effective Connectivity from the Left Inferior Frontal Area to other Areas is Associated with Better Phonological Decoding in Dyslexic Readers
(Frontiers Research Foundation, 2010-12-02)Functional neuroimaging studies suggest that neural networks that subserve reading are organized differently in dyslexic readers (DRs) and typical readers (TRs), yet the hierarchical structure of these networks has not ... -
MRI and Neuropsychological Correlates of Carbon Monoxide Exposure: A Case Report
(National Institute of Environmental Health Sciences, 2002-10)A 45-year-old woman experienced long-term, chronic exposure to carbon monoxide in the restaurant kitchen where she was employed as a cook. After returning to the restaurant after 5 days off work, she noticed that her ...
