Brain Connectivity in Disorders of Consciousness
The last 10 years witnessed a considerable increase in our knowledge of brain function in survivors to severe brain injuries with disorders of consciousness (DOC). At the same time, a growing interest developed for the use of functional neuroimaging as a new diagnostic tool in these patients. In this context, particular attention has been devoted to connectivity studies-as these, more than meas...
متن کاملVoluntary brain processing in disorders of consciousness.
BACKGROUND Disentangling the vegetative state from the minimally conscious state is often difficult when relying only on behavioral observation. In this study, we explored a new active evoked-related potentials paradigm as an alternative method for the detection of voluntary brain activity. METHODS The participants were 22 right-handed patients (10 traumatic) diagnosed as being in a vegetativ...
متن کاملBrain-computer interfacing in disorders of consciousness.
BACKGROUND Recent neuroimaging research has strikingly demonstrated the existence of covert awareness in some patients with disorders of consciousness (DoC). These findings have highlighted the potential for the development of simple brain-computer interfaces (BCI) as a diagnosis in behaviourally unresponsive patients. OBJECTIVES This study here reviews current EEG-based BCIs that hold potent...
متن کاملTowards an effective definition of death and disorders of consciousness.
There exists much controversy in providing an effective definition of human death, largely due to the lack of a rigorous separation and ordered formulation of three distinct elements: a universally accepted definition of death, the medical criterion (anatomical substrata) for determining that death has occurred, and the tests to prove that the criterion has been satisfied. The papers herein rev...
متن کاملSpectral Signatures of Reorganised Brain Networks in Disorders of Consciousness
Theoretical advances in the science of consciousness have proposed that it is concomitant with balanced cortical integration and differentiation, enabled by efficient networks of information transfer across multiple scales. Here, we apply graph theory to compare key signatures of such networks in high-density electroencephalographic data from 32 patients with chronic disorders of consciousness,...
