Diagnostic Techniques, Neurological Categories.
 |
Electroencephalography - Recording of electric currents developed in the brain by means of electrodes applied to the scalp, to the surface of the brain, or placed within the substance of the brain. |
|
Magnetoencephalography - The measurement of magnetic fields over the head generated by electric currents in the brain. As in any electrical conductor, electric fields in the brain are accompanied by orthogonal magnetic fields. The measurement of these fields provides information about the localization of brain activity which is complementary to that provided by electroencephalography. Magnetoencephalography may be used alone or together with electroencephalography, for measurement of spontaneous or evoked activity, and for research or clinical purposes. |

Neurologic Examination |
|
Spinal Puncture - Tapping of the subarachnoid space in the lumbar region, usually between the third and fourth lumbar vertebrae. |
