The locked-in syndrome (pseudocoma) describes patients who are awake and conscious
but selectively deefferented, ie, have no means of producing speech, limb or facial …

The last decade has seen a growing interest in hybrid electrically conducting
nanocomposites. This article aims to provide a detailed overview of the present status of …

Sensory stimuli are used to evaluate and to restore cognitive functions and consciousness in
patients with a disorder of consciousness (DOC) following a severe brain injury. Although …

Evoked potentials and EEGs record punctuate electrical activity at electrode sites. To
represent the overall potential distribution on the entire scalp it is necessary to interpolate …

Abstract Description of mapping methods using spherical splines, both to interpolate scalp
potentials (SPs), and to approximate scalp current densities (SCDs). Compared to a …

Methods: Auditory evoked potentials (AEPs) to the subject's own name and to seven other
first names were recorded in ten normal adults during wakefulness, in both passive listening …

Background A major challenge in the management of severely brain-injured patients with
altered states of consciousness is to estimate their residual perception of the environment …

Wallerian degeneration in the CNS and PNS consists of degradation and phagocytosis of
axons and their myelin sheath distal to the site of injury. This process of degeneration, which …

Scalp current density (SCD) makes possible the identification of scalp sources and sinks of
current. SCD is reference independent and its peaks and troughs are sharper than those of …

In rats, the firing sequences observed in hippocampal ensembles during spatial learning are
replayed during subsequent sleep, suggesting a role for posttraining sleep periods in the …
