EEG of patients in coma after traumatic brain injury reflects physical parameters of auditory stimulation but not its emotional content

The reactivity to the acoustic features of emotional stimulation in patients in coma should be investigated further as a marker of patients’ recovery.

Analysis of Consciousness Level Using Galvanic Skin Response during Therapeutic Effect

These patients were aware of therapeutic affect although they were unconscious, and level of consciousness was classified with 92.7% success using various decision tree algorithms and Random Forest was the method which provides higher accuracy compared to all other methods.

Electrophysiological and Neuroimaging Studies – During Resting State and Sensory Stimulation in Disorders of Consciousness: A Review

The important findings of resting-state as well as sensory stimulation methods and the stimuli proven to be successful in the assessment of consciousness are presented and ideas for future research are provided.

Physiological feelings

Consciousness revealed: new insights into the vegetative and minimally conscious states.

By demonstrating that a behaviourally unresponsive patient could communicate by means of his/her thoughts using functional MRI, these new techniques open up a new direction of research into the development of more sophisticated communication devices that may be used more generally by patients with disorders of consciousness.

Quantification of clinical scores through physiological recordings in low-responsive patients: a feasibility study

Preliminary results are promising considering that this is the first attempt to describe the clinical state of low-responsive patients in such a global and quantitative way and this new model could complement the clinical scores based on objective measurements in order to increase diagnostic reliability.



Neuroanatomical correlates of electrodermal skin conductance responses.

Several lesion loci were consistently associated with defective electrodermal responding: the ventromedial frontal region, the right inferior parietal region, and the anterior cingulate gyrus.

Results suggest a wide range of cortical information processing in coma, including semantic processing, and the question is discussed of whether, and to what extent, these processing operations are related to conscious awareness of stimuli.

Event related brain potentials (ERPs) provide information about cortical processing in severe neurological patients whose cognitive abilities cannot be expressed in their behavior. In coma, ERPs

Prognostic Value of Evoked Responses and Event-Related Brain Potentials in

It is concluded that objective prognostication is enhanced by the use of electrophysiological tests in comatose patients with coma of different etiologies and an approach that combines clinical and electrophysics values provides optimal prediction of outcome and level of disability.

Affective reactions to acoustic stimuli.

The data suggest that acoustic cues activate the appetitive and defensive motivational circuits underlying emotional expression in ways similar to pictures.

Autonomic responses to meaningful and non-meaningful auditory stimuli in Coma

The lowest MCS (Munich Coma Scale) vigilance grade at which patients responded when called by their names was determined and revealed that the first reactions of poisoned patients to their names are primarily elicited by the physical properties of the stimulus.
