abstract = {In the past two decades, many studies have shown the
paradoxical efficacy of zolpidem, a hypnotic used to induce
sleep, in transiently alleviating various disorders of
consciousness such as traumatic brain injury (TBI),
dystonia, and Parkinson’s disease. The mechanism of action
of this effect of zolpidem is of great research interest. In
this case study, we use magnetoencephalography (MEG) to
investigate a fully conscious, ex-coma patient who suffered
from neurological difficulties for a few years due to
traumatic brain injury. For a few years after injury, the
patient was under medication with zolpidem that drastically
improved his symptoms. MEG recordings taken before and after
zolpidem showed a reduction in power in the theta-alpha
(4–12 Hz) and lower beta (15–20 Hz) frequency bands.
An increase in power after zolpidem intake was found in the
higher beta/lower gamma (20–43 Hz) frequency band.
Source level functional connectivity measured using
weighted-phase lag index showed changes after zolpidem
intake. Stronger connectivity between left frontal and
temporal brain regions was observed. We report that zolpidem
induces a change in MEG resting power and functional
connectivity in the patient. MEG is an informative and
sensitive tool to detect changes in brain activity for TBI.},
