Magnetic Resonance Imaging (MRI) and Decline of Aging Aviator Performance

2014-08-27 03:13:47 | BioPortfolio

Summary

The primary purpose of this study is to apply state-of-the-art Magnetic Resonance Imaging (MRI) and Magnetic Resonance Spectroscopic Imaging (MRSI) techniques to measure changes over time in the brain.

Description

We expect that MRI and MRSI techniques will be a useful adjunct in research efforts to understand individual differences in performance of a complex attention-demanding task, such as flying a plane or driving a car. Other predictors of change in performance of a complex task may include simple tests of processing speed and working memory, past training and recent practice of the task, and genetic risk factors for degenerative brain disease. In this project, we will examine whether baseline MR measures are as useful as longitudinal MR measures in predicting amount of change over time in task performance.

This research is part of a long-term effort to achieve earlier identification of individuals at risk of decline and ultimately minimize loss of function.

Evaluation of Age- and Alzheimer's Disease-Related Memory Disorder

The purpose of this study is to examine how a part of the brain called the hippocampus contributes to memory changes that occur with aging and Alzheimer's disease (AD). Memory problems ar...

Protocol Memory Deficit in Patients With Obstructive Sleep Apnea Syndrome

The main objective of this study is to evaluate the evolution of memory deficit (verbal episodic memory, procedural memory, working memory, short-term memory) in Sleep Apnea Obstructive Sy...

Eye Blink Response in Healthy Volunteers and Adults With Schizophrenia

The purpose of this study is to explore how the brain works during particular memory tasks in people with schizophrenia and healthy volunteers. Research has shown that patients with schiz...

Anti-Inflammatory Treatment for Age-Associated Memory Impairment: A Double-Blind Placebo-Controlled Trial

This project is designed to study whether anti-inflammatory drugs, such as celecoxib, may delay age-related mental decline. We are also looking at genetic risk and brain structure as poten...

Dopaminergic Effects on Cortical Function in Tourette's (Levodopa Protocol)

Dr. Kevin J. Black at Washington University is conducting a study to learn whether we can use MRI scans to test dopamine function in the brain and to determine whether the brain performs m...

PubMed Articles [10151 Associated PubMed Articles listed on BioPortfolio]

Trait anxiety is associated with a decreased visual working memory capacity for faces.

Recent work has suggested that anxiety restricts working memory capacity, which may underlie a wide range of cognitive symptoms in anxiety. However, previous literature on the anxiety-visual working m...

Neuroevolution of a Modular Memory-Augmented Neural Network for Deep Memory Problems.

We present Modular Memory Units (MMUs), a new class of memory-augmented neural network. MMU builds on the gated neural architecture of Gated Recurrent Units (GRUs) and Long Short Term Memory (LSTMs), ...

Olfactory modulation of colour working memory: How does citrus-like smell influence the memory of orange colour?

Olfactory modulation of vision is not well understood whereas visual modulation of olfaction has been more fully investigated. This study aimed to reveal in a simple manner whether there is olfactory ...

Memory: Theta Rhythm Couples Periodic Reactivation during Memory Retrieval.

Memory retrieval involves the reactivation of memory traces distributed throughout the brain. New research suggests that these memory reactivations have an oscillatory nature and that they are coupled...

Opinion: Virtual memory CD8 T cells and lymphopenia-induced memory CD8 T cells represent a single subset: homeostatic memory T cells.

It is well established that lymphopenia induces the formation of the memory-phenotype T cells without the exposure to foreign antigens. More recently, the memory-phenotype antigen-inexperienced memory...

Medical and Biotech [MESH] Definitions

Type of declarative memory, consisting of personal memory in contrast to general knowledge.

A neuropsychological test designed to assess different memory functions. It may incorporate an optional cognitive exam (Brief Cognitive Status Exam) that helps to assess memory related cognitive function.

Neurological process involving the conversion of learned information into long-term memory.

Complex mental function having four distinct phases: (1) memorizing or learning, (2) retention, (3) recall, and (4) recognition. Clinically, it is usually subdivided into immediate, recent, and remote memory.

Temporary storage of information for a few seconds to hours, as opposed to long-term memory which refers to material stored for days, years, or a lifetime.
