Objective Assessment of Olfactory Function Using Functional Magnetic Resonance Imaging (fMRI)
IEEE Transactions on Instrumentation and Measurement, 2010Impairment of the olfactory sensibility can be an indicator of neurode generative disorders, such as Alzheimer's disease and Parkinson's disease. The problem lies in obtaining an objective quantitative analysis of olfactory response. For this task, we will use functional magnetic resonance imaging (fMRI) and a device that will provide a selective and ...

Functional magnetic resonance imaging (fMRI)
2004Abstract The first report of localized changes in cerebral blood oxygenation in the occipital cortex following visual stimulation in humans (Belliveau et al. 1991) was of seminal importance to neuropsychiatric research. Only 3 years following this technological development, which enabled non-invasive visualization of in vivo human brain ...

Functional Magnetic Resonance Imaging (fMRI)
2002Glossary Block Design: Experimental design for functional neuroimaging in which an attempt is made to put the subject's brain in a steady state of activity by using the same type of task for an extended period, of time (typically 20-60 seconds), and then comparing the brain activation during that block with other blocks which use a different task.

The Neuroscience of Functional Magnetic Resonance Imaging fMRI for Deception Detection
The American Journal of Bioethics, 2007As scientists developing the use of functional magnetic resonance imaging (fMRI) to detect deception, we feel obligated to present both the capabilities and limitations of this emerging technology....

Functional Magnetic Resonance Imaging (fMRI) in Children Sedated With Propofol or Midazolam
Journal of Neurosurgical Anesthesiology, 2009Magnetic resonance imaging (MRI) requires patient immobility and children generally need to be sedated. The ideal sedative agent for functional MRI (fMRI) should only minimally hamper the neurophysiologic effect of the administered sensorial stimulation. This study compares the effect of propofol and midazolam on the fMRI auditory activation pattern in

Functional Magnetic Resonance Imaging (fMRI)
2016Functional magnetic resonance imaging (fMRI) is undoubtedly one of the most common techniques used in the cognitive neurosciences and neuroeconomics. The methods section of fMRI papers are oftentimes filled with jargon. We hope to clarify this jargon by defining and explaining the most fundamental concepts.

Presurgical Functional Magnetic Resonance Imaging (fMRI)
Clinical Neuroradiology, 2007Preoperative functional magnetic resonance imaging (fMRI) permits noninvasive measurement, localization and lateralization of important functions of the human brain in patients with brain tumors, facilitating selection of the least harmful treatment and surgery which preserves function.

Studying Language with Functional Magnetic Resonance Imaging (fMRI)
2019Since the discoveries of language-sensitive brain areas in the late nineteenth century, the localization of the language network in the brain has been the subject of neurolinguistics research. Especially during the times of the two world wars and until the 1980s, head and brain injuries in soldiers as well as in civil patients served as the main data ...

Current Medical Imaging Reviews, 2010
Neurosurgical resection of brain lesions aims to maximize excision while minimizing the risk of permanent injury to the surrounding intact brain tissue and resulting neurological deficits. While direct electrical cortical stimulation at the time of surgery allows the precise identification of essential cortex, it cannot provide information ...

Busting the myths of functional magnetic resonance imaging (fMRI)
PsyPag Quarterly, 2020For almost 30 years, functional magnetic resonance imaging (fMRI) has made a splash in neuroscientific fields, contributing to cognitive, social and sensory domains. But with fMRI being used to support big claims about the nature of our brains, it is important to consider how much fMRI can tell us about brain activity and why a more careful approach is
