It has been suggested that this article or section be merged into Neuroimaging. (Discuss)

Brain mapping is a set of neuroscience techniques predicated on the mapping of (biological) quantities or properties onto spatial representations of the (human or non-human) brain resulting in maps. All neuroimaging can be considered part of brain mapping. Brain mapping can be conceived as a higher form of neuroimaging, producing brain images supplemented by the result of additional (imaging or non-imaging) data processing or analysis, such as maps projecting (measures of) behaviour onto brain regions (see fMRI). Brain Mapping techniques are constantly evolving, and rely on the development and refinement of image acquisition, representation, analysis, visualization and interpretation techniques. Functional and structural neuroimaging are at the core of the mapping aspect of Brain Mapping. Wikipedia does not have an article with this exact name. ... Neuroimaging includes the use of various techniques to either directly or indirectly image the structure, function, or pharmacology of the brain. ... The word mapping has several senses: In mathematics and related technical fields, it is some kind of function: see map (mathematics). ...

Neuroimaging includes the use of various techniques to either directly or indirectly image the structure, function, or pharmacology of the brain. ... Functional Magnetic Resonance Imaging (or fMRI) describes the use of MRI to measure hemodynamic signals related to neural activity in the brain or spinal cord of humans or other animals. ...

History

In the late 1980s in the United States, the Institute of Medicine of the National Academy of Science was commissioned to establish a panel to investigate the value of integrating neuroscientific information across a variety of techniques [1]. Of specific interest is using structural and functional magnetic resonance imaging (MRI), EEG, positron emission tomography (PET) and other non-invasive scanning techniques to map anatomy, physiology, perfusion, function and phenotypes of the human brain. Both healthy and diseased brains may be mapped to study memory, learning, aging, and drug effects in various populations such as schizophrenics, autistics, and clinically depressed people. This led to the establishment of the Human Brain Project [2]. Following a series of meetings, the International Consortium for Brain Mapping (ICBM) evolved [3]. The ultimate goal is to develop flexible computational brain atlases. The mri are a fictional alien species in the Faded Sun Trilogy of C.J. Cherryh. ... EEG can mean: Electroencephalography - the method and science of recording and interpreting traces of brain electrical activity as recorded from the skull surface or the device used to record such traces Emperor Entertainment Group - A Hong Kong entertainment company. ...

Brain Mapping (Research - UCLA Gateway) (224 words)
Neurologists may be well acquainted with the brain’s gross anatomy, but this absence of exactitude poses problems that have potential implications for researchers as well as for surgeons trying to navigate the corrugations of this most essential organ.
The atlas database comprises high-definition structural maps — from gross anatomy to microscopic detail — based on scans of the brains of some 7,000 individuals and referenced for age, race, gender, educational background, genetic composition and other distinguishing characteristics.
Layered over the anatomical maps are brain functions such as memory, emotion, language and speech.
Neuroimaging - Wikipedia, the free encyclopedia (1773 words)
Typically used for quickly viewing brain injuries, CT scanning has a computer program that uses a set of algebraic equations to estimate how much of an x-ray beam is absorbed in a small volume of the brain.
CT scans are primarily used for evaluating swelling from tissue damage in the brain and in assessment of ventricle size.
X-ray images of the ventricular system within the brain were obtained by injection of filtered air directly into one or both lateral ventricles of the brain.
