Electrical stimulation of a small brain area reversibly disrupts consciousness reports on a electric brain stimulation study of a patient in the extreme capsule close to the anterior-dorsal insula and the neighboring claustrum.
- biphasic waves at 14 mA (50 Hz, 0.2-ms pulse width, 3- to 10-second train duration)
Electric stimulation at the site in question resulted in:
- "immediate impairment of consciousness"
- "arrest of reading, onset of blank staring, unresponsiveness to auditory or visual commands, and slowing of spontaneous respiratory movements"
- "Occasionally, the induced impairment of consciousness was associated with scanty, perseverative, and incomprehensible verbal output consisting of one or two syllables, with a confused look on the face"
- "able to continue repetitive movements with the tongue and hands during stimulation" if start before the stimulation
- "The patient returned to baseline as soon as the stimulation stopped with no recollection of the events during the stimulation period"
