Probing consciousness with event-related potentials in the vegetative state.
OBJECTIVE Probing consciousness in noncommunicating patients is a major medical and neuroscientific challenge. While standardized and expert behavioral assessment of patients constitutes a mandatory step, this clinical evaluation stage is often difficult and doubtful, and calls for complementary measures which may overcome its inherent limitations. Several functional brain imaging methods are c...
متن کاملHow vegetative is the vegetative state? Preserved semantic processing in VS patients--evidence from N 400 event-related potentials.
Event-related potentials (ERPs) can provide valuable information about cognitive capabilities in severely brain-damaged patients. This study examined 120 patients with severe brain damage using event related potentials ERPs (N 400) to gain information about their remaining semantic processing capabilities and to contribute to differential diagnosis. Patients were classified into three diagnosti...
متن کاملNative-like Event-related Potentials in Processing the Second Language Syntax: Late Bilinguals
Background: The P600 brain wave reflects syntactic processes in response to different first language (L1) syntactic violations, syntactic repair, structural reanalysis, and specific semantic components. Unlike semantic processing, aspects of the second language (L2) syntactic processing differ from the L1, particularly at lower levels of proficiency. At higher L2 proficiency, syntactic violatio...
متن کاملLate recovery after traumatic, anoxic, or hemorrhagic long-lasting vegetative state.
OBJECTIVES Late recovery of awareness in vegetative state (VS) is considered as an exceptional outcome, and has been reported prevalently after traumatic brain injury (TBI). The present prospective study aimed to verify frequency of late recovery (later than 1 year postonset in TBI and 3 months postonset in patients without TBI) of responsiveness and consciousness in traumatic and nontraumatic ...
متن کاملLate event-related potentials and psychopathology.
Event-related potentials include not only the short duration evoked potentials (EPs) associated with sensory stimulation or motor response but also longer duration potentials such as the contingent negative variation, for which the eliciting events are more complex. For EPs there seems to be a relationship between the latency of the EP component and the degree of influence by more cognitive psy...
