Journal ArticleDOI
Monitoring the patient's EEG during echo planar MRI
TL;DR: By careful selection and arrangement of analog multiplexed cable-telemetry equipment to eliminate both ferrous and RF sources, a stable, readable EEG can be obtained without interfering with the diagnostic quality of the MRI.
Journal ArticleDOI
Sleep-inducing effects of low doses of melatonin ingested in the evening.

TL;DR: Exogenous melatonin may be useful in treating insomnia and nocturnal melatonin secretion may be involved in physiologic sleep onset, as assessed with mood and performance tests administered on the morning after treatment.
Journal ArticleDOI
MEG versus EEG localization test using implanted sources in the human brain
David Cohen,B N Cuffin,K Yunokuchi,Maniewski R,C. Purcell,G. R. Cosgrove,John R. Ives,J G Kennedy,Donald L. Schomer +8 more
TL;DR: The results suggest that the MEG offers no significant advantage over the EEG in localizing a focal source, however, this does not diminish other uses of the M EG.
Journal ArticleDOI
Non-invasive epileptic focus localization using EEG-triggered functional MRI and electromagnetic tomography
Margitta Seeck,François Lazeyras,Christoph M. Michel,Olaf Blanke,Christian A. Gericke,John R. Ives,Jacqueline Delavelle,Xavier Golay,Charles-Antoine Haenggeli,N. De Tribolet,Theodor Landis +10 more
TL;DR: In this paper, EEG-triggered functional MR imaging (fMRI) and 3D EEG source localization were combined to map the primary electrical source with high spatial resolution for non-invasive localization of focal epileptogenic discharges.
Journal ArticleDOI
EEG-triggered echo-planar functional MRI in epilepsy
Steven Warach,John R. Ives,Gottfried Schlaug,Mahesh R. Patel,David Darby,Venkatesan Thangaraj,Robert R. Edelman,Donald L. Schomer +7 more
TL;DR: Results are reported in two patients who showed focally higher signal intensity, reflective of increased local blood flow, in ultrafast functional MRI timed to epileptic discharges recorded while the patients were in the imager and compared with images not associated with discharges.
