Clinical Trials [328 Associated Clinical Trials listed on BioPortfolio]

Functional Magnetic Resonance Imaging - Synthetic Aperture Magnetometry (fMRI-SAM) and Alzheimer's Disease

The aim of the protocol is to study the resting brain activation profile of 3 groups of people, using a new fMRI procedure, called fMRI-SAM. fMRI-SAM will be applied to 25 Alzheimer's dise...

Tests of Functional Magnetic Resonance Imaging Techniques

Background: - Functional magnetic resonance imaging (fMRI) is used to study the brain. It takes a series of pictures that can be used to look at how the brain processes information. It is...

A Functional Magnetic Resonance Imaging (fMRI) Study in Overweight and Obese Men (0000-103)

This study will determine whether BOLD-fMRI can be used to probe hunger and satiety states in healthy overweight or obese men and also whether fasted/fed fMRI signals can be modulated by s...

Activating and Identifying Neural Responses to Social Rejection: a Combined tDCS and fMRI Study

This research study identifies neural pathways regulating negative moods during rejection by combining transcranial direct current stimulation (tDCS) and fMRI in a sample of healthy contro...

Insulin Modulation of fMRI Connectivity in Healthy Adults

This study evaluates the effects of changing insulin levels on brain activity. Participants will complete functional magnetic resonance imaging (fMRI) scans during fasting conditions, then...

The voxel-wise analysis of false negative fMRI activation in regions of provoked impaired cerebrovascular reactivity.

Task-evoked Blood-oxygenation-level-dependent (BOLD-fMRI) signal activation is widely used to interrogate eloquence of brain areas. However, data interpretation can be improved, especially in regions ...

Test-retest reliability of task-based and resting-state blood oxygen level dependence and cerebral blood flow measures.

Despite their wide-spread use, only limited information is available on the comparative test-retest reliability of task-based functional and resting state magnetic resonance imaging measures of blood ...

Age attenuates noise and increases symmetry of head movements during sleep resting-state fMRI in healthy neonates, infants, and toddlers.

Newborns produce spontaneous movements during sleep that are functionally important for their future development. This nuance has been previously studied using animal models and more recently using mo...

Orbitofrontal dysfunction during the reward process in adults with ADHD: An fMRI study.

The present study aimed to detect differences in the reward response between adults with attention deficit hyperactivity disorder (ADHD) and healthy controls (HCs) using functional magnetic resonance ...

Glutamatergic response to a low load working memory paradigm in the left dorsolateral prefrontal cortex in patients with mild cognitive impairment: a functional magnetic resonance spectroscopy study.

Working memory deficits have been widely reported in mild cognitive impairment (MCI). However, the neural mechanisms of working memory dysfunction in MCI have not been clearly understood. In this stud...

Medical and Biotech [MESH] Definitions

Healthy People Programs are a set of health objectives to be used by governments, communities, professional organizations, and others to help develop programs to improve health. It builds on initiatives pursued over the past two decades beginning with the 1979 Surgeon General's Report, Healthy People, Healthy People 2000: National Health Promotion and Disease Prevention Objectives, and Healthy People 2010. These established national health objectives and served as the basis for the development of state and community plans. These are administered by the Office of Disease Prevention and Health Promotion (ODPHP). Similar programs are conducted by other national governments.

Mechanism by which changes in neural activity are tightly associated with regional cortical HEMODYNAMICS and metabolism changes. The association is often inferred from NEUROIMAGING signals (e.g., fMRI; or NIR SPECTROSCOPY).

Governmental guidelines and objectives pertaining to public food supply and nutrition including recommendations for healthy diet and changes in food habits to ensure healthy diet.

Surgical reinnervation of a denervated peripheral target using a healthy donor nerve and/or its proximal stump. The direct connection is usually made to a healthy postlesional distal portion of a non-functioning nerve or implanted directly into denervated muscle or insensitive skin. Nerve sprouts will grow from the transferred nerve into the denervated elements and establish contact between them and the neurons that formerly controlled another area.

Process of evaluating the health of a patient and determining if they are healthy enough for surgery.
