Odor Fear Conditioning Modifies Piriform Cortex Local Field Potentials Both During Conditioning And During Post-Conditioning Sleep, Dylan C. Barnes, Julie Chapuis, Dipesh Chaudhury, Donald A. Wilson Mar 2011

Odor Fear Conditioning Modifies Piriform Cortex Local Field Potentials Both During Conditioning And During Post-Conditioning Sleep, Dylan C. Barnes, Julie Chapuis, Dipesh Chaudhury, Donald A. Wilson

Publications and Research

Background: Sleep plays an active role in memory consolidation. Sleep structure (REM/Slow wave activity [SWS]) can be modified after learning, and in some cortical circuits, sleep is associated with replay of the learned experience. While the majority of this work has focused on neocortical and hippocampal circuits, the olfactory system may offer unique advantages as a model system for exploring sleep and memory, given the short, non-thalamic pathway from nose to primary olfactory (piriform cortex), and rapid cortex-dependent odor learning.

Methodology/Principal Findings: We examined piriform cortical odor responses using local field potentials (LFPs) from freely behaving Long-Evans hooded rats over …

The Implications Of Chronic Pain Models For Rehabilitation Of Distal Radius Fracture, Saurabh Mehta, Joy Macdermid, Mary Tremblay Mar 2011

The Implications Of Chronic Pain Models For Rehabilitation Of Distal Radius Fracture, Saurabh Mehta, Joy Macdermid, Mary Tremblay

Physical Therapy Faculty Research

Distal radius fracture (DRF) is the most common fracture and usually occurs as a result of a fall. Most patients recover following DRF with minimal residual pain or disability; however, a small subset of patients continue to experience pain and disability even one year after the injury. Currently, there are no practice guidelines for early identification and treatment of patients who are potentially at greater risk of developing these adverse outcomes. As a result, hand therapy management of patients following DRF does not incorporate screening of these at-risk patients. The objective of this paper is to apply constructs from learned …

Department of Psychiatry and Human Behavior Faculty Papers

Age-Related Macular Degeneration (AMD) is the leading cause of severe vision loss in older adults and impairs the ability to read, drive, and live independently and increases the risk for depression, falls, and earlier mortality. Although new medical treatments have improved AMD's prognosis, vision-related disability remains a major public health problem. Improving Function in AMD (IF-AMD) is a two-group randomized, parallel design, controlled clinical trial that compares the efficacy of Problem-Solving Therapy (PST) with Supportive Therapy (ST) (an attention control treatment) to improve vision function in 240 patients with AMD. PST and ST therapists deliver 6 one-hour respective treatment sessions …

Universal Or Indicated Screening In Primary Care?, Matthew Wintersteen, Md Feb 2011

Universal Or Indicated Screening In Primary Care?, Matthew Wintersteen, Md

Department of Psychiatry and Human Behavior Faculty Papers

To the Editor: In the November 2010 issue, Schmitt and colleagues (1) reported that the duration of visits increased when depression screening was conducted in primary care. This report is timely given recent recommendations for both adult and pediatric screening for depression in primary care. Schmitt and colleagues examined data representative of more than 641 million primary care visits in2005–2007 and found that when depression screening was documented in patients’ records, physicians’ time with patients increased significantly.

Participating In A Community Of Learners Enhances Resident Perceptions Of Learning In An E-Mentoring Program: Proof Of Concept, Timona Obura, William. E. Brant, Fiona Miller, I. J. Parboosingh Jan 2011

Participating In A Community Of Learners Enhances Resident Perceptions Of Learning In An E-Mentoring Program: Proof Of Concept, Timona Obura, William. E. Brant, Fiona Miller, I. J. Parboosingh

Obstetrics and Gynaecology, East Africa

Background

Community learning and e-mentoring, learning methods used in higher education, are not used to any extent in residency education. Yet both have the potential to enhance resident learning and, in the case of community learning, introduce residents to basic lifelong learning skills. We set out to determine whether residents participating in an Internet based e-mentoring program would, with appropriate facilitation, form a community of learners (CoL) and hold regular community meetings. We also determined resident and faculty perceptions of CoL and Internet sessions as effective learning experiences.

Methods

A six-month e-mentoring pilot was offered to 10 Radiology residents in …

A Test Of The Role Of The Medial Temporal Lobe In Single-Word Decoding., Karol Osipowicz, Tyler Rickards, Atif Shah, Ashwini Sharan, Michael Sperling, Waseem Kahn, Joseph Tracy

Department of Neurology Faculty Papers

The degree to which the MTL system contributes to effective language skills is not well delineated. We sought to determine if the MTL plays a role in single-word decoding in healthy, normal skilled readers. The experiment follows from the implications of the dual-process model of single-word decoding, which provides distinct predictions about the nature of MTL involvement. The paradigm utilized word (regular and irregularly spelled words) and pseudoword (phonetically regular) stimuli that differed in their demand for non-lexical as opposed lexical decoding. The data clearly showed that the MTL system was not involved in single word decoding in skilled, native …


Short-Term And Long-Term Effects Of Orthopedic Biodegradable Implants, Ami R. Amini, James S. Wallace, Syam P. Nukavarapu Jan 2011

Short-Term And Long-Term Effects Of Orthopedic Biodegradable Implants, Ami R. Amini, James S. Wallace, Syam P. Nukavarapu

Articles - Patient Care

Presently, orthopedic and oral/maxillofacial implants represent a combined $2.8 billion market, a figure expected to experience significant and continued growth. Although traditional permanent implants have been proved clinically efficacious, they are also associated with several drawbacks, including secondary revision and removal surgeries. Non-permanent, biodegradable implants offer a promising alternative for patients, as they provide temporary support and degrade at a rate matching tissue formation, and thus, eliminate the need for secondary surgeries. These implants have been in clinical use for nearly 25 years, competing directly with, or maybe even exceeding, the performance of permanent implants. The initial implantation of biodegradable …


Anti-Saccade Performance Predicts Executive Function And Brain Structure In Normal Elders, J. B. Mirsky, H. W. Heuer, A. Jafari, J. H. Kramer, A. K. Schenk, Indre Viskontas, B. L. Miller, A. L. Boxer Jan 2011

Anti-Saccade Performance Predicts Executive Function And Brain Structure In Normal Elders, J. B. Mirsky, H. W. Heuer, A. Jafari, J. H. Kramer, A. K. Schenk, Indre Viskontas, B. L. Miller, A. L. Boxer

Psychology

Objective—To assess the neuropsychological and anatomical correlates of anti-saccade (AS) task performance in normal elders.

Background—The AS task correlates with neuropsychological measures of executive function and frontal lobe volume in neurological diseases, but has not been studied in a well-characterized normal elderly population. Because executive dysfunction can indicate an increased risk for cognitive decline in cognitively normal elders, we hypothesized that AS performance might be a sensitive test of age-related processes that impair cognition.

Method—The percentage of correct AS responses was evaluated in forty-eight normal elderly subjects and compared with neuropsychological test performance using linear regression analysis …


Multimodal Cuing Of Autobiographical Memory In Semantic Dementia, D. L. Greenberg, J. M. Ogar, Indre Viskontas, M. L. Gorno Tempini, B. Miller, B. J. Knowlton Jan 2011

Multimodal Cuing Of Autobiographical Memory In Semantic Dementia, D. L. Greenberg, J. M. Ogar, Indre Viskontas, M. L. Gorno Tempini, B. Miller, B. J. Knowlton

Psychology

OBJECTIVE: Individuals with semantic dementia (SD) have impaired autobiographical memory (AM), but the extent of the impairment has been controversial. According to one report (Westmacott, Leach, Freedman, & Moscovitch, 2001), patient performance was better when visual cues were used instead of verbal cues; however, the visual cues used in that study (family photographs) provided more retrieval support than do the word cues that are typically used in AM studies. In the present study, we sought to disentangle the effects of retrieval support and cue modality.

METHOD: We cued AMs of 5 patients with SD and 5 controls with words, simple …

Management Of Hypertension Among Patients With Coronary Heart Disease, O. Olafiranye, F. Zizi, P. Brimah, G. Jean-Louis, A. N. Makaryus, S. Mcfarlane, G. Ogedegbe Jan 2011

Management Of Hypertension Among Patients With Coronary Heart Disease, O. Olafiranye, F. Zizi, P. Brimah, G. Jean-Louis, A. N. Makaryus, S. Mcfarlane, G. Ogedegbe

Journal Articles

Evidence suggests that coronary heart disease (CHD) is the most common outcome of hypertension. Hypertension accelerates the development of atherosclerosis, and sustained elevation of blood pressure (BP) can destabilize vascular lesions and precipitate acute coronary events. Hypertension can cause myocardial ischemia in the absence of CHD. These cardiovascular risks attributed to hypertension can be reduced by optimal BP control. Although several antihypertensive agents exist, the choice of agent and the appropriate target BP for patients with CHD remain controversial. In this succinct paper, we examine the evidence and the mechanisms for the linkage between hypertension and CHD and we discuss …

Learning From Mistakes: Improving Initial Fingertip Force Scaling By Observing Lifting Errors, Gavin Buckingham, Minnie Tang, Paul Gribble, Melvyn A. Goodale Jan 2011

Learning From Mistakes: Improving Initial Fingertip Force Scaling By Observing Lifting Errors, Gavin Buckingham, Minnie Tang, Paul Gribble, Melvyn A. Goodale

Psychology Presentations

• When lifting objects that are lighter or heaver than we expect them to be, individuals typically misapply forces in a way that reflects their prior expectations of heaviness.

• Because we lift in this predictive way, large and small cubes elicit these characteristic errors even when they are adjusted to have equal mass. Lifters will apply too much force to a large cube and substantially less force to a small cube – errors that are rapidly corrected with repeated lifts (Flanagan & Beltzner, 2000).

• When watching others lift objects, an observer’s motor system automatically reacts in a way …

Hiv-1 Effects On Neuropsychological Performance In A Resource-Limited Country, Zambia, Gabriel Holguin, Mwanza Banda, Elizabeth J. Willen, Costantine Malama, Kaseya O. Chiyenu, Victor C. Mudenda, Charles Wood

Nebraska Center for Virology: Faculty Publications

Zambia has substantially been affected by the HIV/AIDS epidemic with prevalence rates at 14% in a population estimated at 12 million. Yet, the extent of HIV-associated neurocognitive disorders (HAND) in this population remains to be clearly understood. A series of culturally appropriate neuropsychological (NP) assessments [International HIV Dementia Scale (IHDS), Color Trails Test 1 and 2, Grooved pegboard Test, and Time Gait Test] were used to test the effects of HIV on NP performance of HIV seropositive and seronegative individuals. Twenty-two percent HIV positive individuals ARV naïve met the criteria for IHDS-defined NP impairment. Gender significantly influenced the performance on …


Suicide Bombing: A Geopolitical Perspective, Haider Naqvi, Syed Faraz Kazim, Shafqat Huma Jan 2011

Suicide Bombing: A Geopolitical Perspective, Haider Naqvi, Syed Faraz Kazim, Shafqat Huma

Department of Psychiatry

Suicide bombing is a very complex phenomenon. It has been a focus of research in recent times. However inherent biases of researchers muddle the picture: researchers from western countries focus the issue around political liberty and notion of democracy, while those from Islamic countries tend to take the afterlife-reward notion as an incentive for suicide bombing. However in order to understand this complex phenomenon it is important to consider the contextual factors. In this review we have attempted to highlight various geopolitical factors which contribute to increased incidence of suicide bombing in South East Asia.

Wayne State University Associated BioMed Central Scholarship

Abstract

Despite the sparseness of the currently available data, there is accumulating evidence of information processing impairment in post-traumatic stress disorder (PTSD). Studies of event-related potentials (ERPs) are the main tool in real time examination of information processing. In this paper, we sought to critically review the ERP evidence of information processing abnormalities in patients with PTSD. We also examined the evidence supporting the existence of a relationship between ERP abnormalities and symptom profiles or severity in PTSD patients. An extensive Medline search was performed. Keywords included PTSD or post-traumatic stress disorder, electrophysiology or EEG, electrophysiology, P50, P100, N100, P2, …
