We describe a technique for recording electroencephalographic and evoked-potential
information directly from the cerebral hemispheres and brain stem, via an endovascular …

A new method for intracranial monitoring of brain electrical activity by means of an intra-
arterial guide wire as electrode is described. We carried out intracranial electro …

✓ Spontaneous and evoked electrical activity from the basal and medial areas of the brain
not accessible in routine electroencephalography (EEG) has been recorded with single and …

The purpose of this prospective study is to show a technique for recording
electroencephalographic activity via an endovascular approach in presurgical evaluation of …

Following transcranial electrical cortex stimulation motor evoked potentials (MEP) were

METHODS For the most part, electroencephalograms were made with an eight channel
Grass ink-writing electroencephalograph. At least twelve electrodes were applied, ten to the …

The use of evoked potential monitoring, both brain-stem acoustic evoked potentials and
somatosensory evoked potentials, is reviewed considering our previous experiences and …

Materials and Methods Patients referred for many neurointerventional procedures are first
