encephalography

 [en-sef″ah-log´rah-fe]
radiography demonstrating the intracranial fluid-containing spaces after the withdrawal of cerebrospinal fluid and introduction of air or other gas; it includes pneumoencephalography and ventriculography.

en·ceph·a·log·ra·phy

(en-sef-ă-log'ră-fē),
Obsolete technique of radiographic representation of the brain. See: pneumoencephalography.
[encephalo- + G. graphō, to write]

encephalography

(ĕn-sĕf′ə-lŏg′rə-fē)
n. pl. encephalogra·phies
Radiographic examination of the brain in which some of the cerebrospinal fluid is replaced with air or another gas that acts as a contrast medium.

en·ceph′a·lo·graph′ic (-ə-lə-grăf′ĭk, -ə-lō-) adj.
en·ceph′a·lo·graph′i·cal·ly adv.

en·ceph·a·log·ra·phy

(en-sef'ă-log'ră-fē)
Radiographic representation of the brain.

encephalography

Any X ray examination of the brain. In air encephalography, the cerebrospinal fluid in the brain ventricles is replaced by air. CT SCANNING and MRI have rendered this very unpleasant procedure obsolete.

Let me begin with a brief explanation of the three most important technological advances in brain research: Positron Emission Tomography (PET), Functional Magnetic Resonance Imaging (fMRI), and Quantitative Encephalography (qEEG).
There also is a lack of EEG and clinical specificity to associate epileptic encephalography with autistic regression, because most children with autistic regression on overnight EEG testing do not have epileptiform activity and there is no clinical difference between children with autistic regression and those with nonregressive ASD.
The Swedish oncology and neurosurgery solutions and services supplier Elekta AB said on Wednesday (23 June) that it would establish an international network of research centres for Elekta Neuromag magneto encephalography (MEG) systems.
Research of this kind goes back to the early days of encephalography (EEG) (Golla, Hutton & Walter, 1943), but it was the work of Roland, Larsen, Lassen & Skinhoj (1980) using regional cerebral blood flow which suggested that motor imagery can be localized to a subset of the motor system.

Following commentary on a study examining subjects' neural responses to olfactory stimulation, international contributors to nine chapters review recent empirical findings using noninvasive imaging techniques including functional magnetic resonance (fMRI), magnetoencephalography (MEG), and a new algorithm applied to encephalography (EEG) recordings, for study of, e.g., the role of the corpus callosum in inter-hemispheric transfer of somatosensory information, aspects of memory, and the post- treatment status of patients with gliomas (the type of brain tumor that Senator Kennedy has).
New chapters have been added on endovascular neurology, diseases of DNA translation, pachymeningitis, and Hashimoto encephalography. Other chapters has been updated to reflect the impact of molecular genetics on the field.
