Intrinsic signal changes accompanying sensory stimulation: functional brain mapping with magnetic resonance imaging.
We report that visual stimulation produces an easily detectable (5-20%) transient increase in the intensity of water proton magnetic resonance signals in human primary visual cortex in gradient echo images at 4-T magnetic-field strength. The observed changes predominantly occur in areas containing gray matter and can be used to produce high-spatial-resolution functional brain maps in humans. Re...
متن کاملIntraoperative Human Functional Brain Mapping Using Optical Intrinsic Signal Imaging
Functional brain mapping strives to describe the brain’s organization as a mosaic of distinct regions, each of which subserves a particular function. Advances in our understanding of functional brain organization over the past decades have been propelled by the availability of increasingly sophisticated methods for assessing various aspects of neuronal activity in vivo. These methods can be bro...
متن کاملHuman Brain Mapping Using Structural and Functional Magnetic Resonance Imaging and Transcranial Magnetic Stimulation
Modern brain research methods such as magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI) and transcranial magnetic stimulation (TMS) have provided essential information of the structure and function of the human brain. However, to be practical in clinics, they need to be optimized for the clinical environment and to be easy to use and robust. At the same time, the re...
متن کاملRole of the mode of sensory stimulation in presurgical brain mapping in which functional magnetic resonance imaging is used.
OBJECT The aim of this study was to evaluate different types of sensory stimulation used to distinguish between microvasculature and venous drainage on functional magnetic resonance (fMR) images with blood oxygen level-dependent (BOLD) contrast. METHODS Seven volunteers received three sensory stimulations. One consisted of small discontinuous automated pokes to the ventral aspect of the right...
