One challenging aspect of the clinical assessment of brain-injured, unresponsive patients is
the lack of an objective measure of consciousness that is independent of the subject’s ability …

Patients surviving severe brain injury may regain consciousness without recovering their
ability to understand, move and communicate. Recently, electrophysiological and …

A common endpoint of general anesthetics is behavioral unresponsiveness [1], which is
commonly associated with loss of consciousness. However, subjects can become disconnected …

Prolonged wakefulness is associated not only with obvious changes in the way we feel and
perform but also with well-known clinical effects, such as increased susceptibility to seizures, …

Background High-density electroencephalography (hd-EEG) combined with transcranial
magnetic stimulation (TMS) provides a direct and non-invasive measure of cortical excitability …

We exploit time reversibility analysis, checking the invariance of statistical features of a series
after time reversal, to detect temporal asymmetries of short-term heart period variability …

Over the last years, a surge of empirical studies converged on complexity-related measures
as reliable markers of consciousness across many different conditions, such as sleep, …

Transcranial magnetic stimulation (TMS) combined with simultaneous high-density
electroencephalography (hd-EEG) represents a straightforward way to gauge cortical excitability and …

We normally assess another individual’s level of consciousness based on her or his ability
to interact with the surrounding environment and communicate. Usually, if we observe …

Increasing evidence shows that anodal transcranial direct current stimulation (tDCS) enhances
cognitive performance in healthy and clinical population. Such facilitation is supposed to …
