Description:
Local paroxysmal discharges of epileptic tissue within the human brain, which may be electrically recorded as voltage spikes in the electroencephalogram, also generate extracranial magnetic fields. These fields were assessed by means of recently developed neuromagnetometric techniques. Surface measurements of magnetic spike field strength in the region of the focus appear sufficient to establish the location, depth, orientation, and polarity of currents underlying the paroxysmal discharge.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barth, D S -- Sutherling, W -- Engel, J Jr -- Beatty, J -- 78040-29867-5/PHS HHS/ -- RR07009/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1982 Nov 26;218(4575):891-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6813968" target="_blank"〉PubMed〈/a〉
