The intraoperative recording of electroencephalographic (EEG) activity began soon after the development and introduction of the EEG as a neurodiagnostic technique. One of the initial clinical applications of the intraoperative…
Digital electroencephalography (EEG) is the simple recording and interpreting of routine EEG using computer-based technology. Quantitative electroencephalography (QEEG) is the processing of digital EEG with various algorithms and displays. There…
Video-EEG monitoring (VEM) includes a variety of techniques used simultaneously to record electrical and behavioral characteristics of paroxysmal disturbances in cerebral function over extended periods. , It has been called…
The term magnetoencephalography (MEG) refers to the recording of the magnetic field of electrocerebral activity. MEG uses specialized equipment and lends itself to source localization using dipole methods and co-registration…
The electroencephalogram (EEG) is an important tool in the evaluation of an infant or child with symptoms referable to the central nervous system (CNS). EEGs are used to assess seizure…
The electroencephalogram (EEG) represents the electrical activity of the brain as recorded from electrodes placed on the scalp. Many clinical neurologists and neurosurgeons do not fully appreciate the potential value…
The development and refinement of instrumentation has been a great asset in the diagnosis of neurologic diseases. With advances in instrumentation, however, physiologists are in danger of making more technologically…
From the time of the ancients to well into the eighteenth century, electricity was regarded as a strange, invisible power. It was differentiated from magnetism in 1600 by Gilbert, but…
