An interactive process model of the nature of representation intrinsically accounts for multiple emergent properties of consciousness, such as being a contentful experiential flow, from a situated and embodied point of view. A crucial characteristic of this model is that content is an internally related property of interactive process, rather than an externally related property as in all other ...

This paper offers a framework for consciousness of internal reality. Recent PET experiments are reviewed, showing partial overlap of cortical activation during self-produced actions and actions observed from other people. This overlap suggests that representations for actions may be shared by several individuals, a situation which creates a potential problem for correctly attributing an action ...

101 In the essay on consciousness, there is careless use of words whose meanings have long been well-defined by psychiatrists. The value of his "levels of wakefulness" is minimal on this account. He is optimistic about the future of consciousness! "My guess just now is that consciousness will sooner or later be described in terms of electronic activity.. ." In his discussion of the psychoneuros...

Episodic memory deficits are predominately the first cognitive impairment in Alzheimer disease (AD). Previous studies have demonstrated that these deficits are specifically linked to autonoetic consciousness impairment, whereas noetic consciousness remains preserved in AD. This study focused on the self-reference effect and examined emotional valence, as it has been shown that emotional content...

We describe a 30 year old woman who presented with thyroid storm. She had non-specific symptoms and few clinical signs of hyperthyroidism despite markedly raised thyroid hormone concentrations. Soon after admission her behaviour became abnormal and her level of consciousness deteriorated. Despite the rapid restoration of thyroid hormone concentrations to normal using conventional therapies, and...

Advances in media and communication technology have opened up new avenues for understanding consciousness through observation of behaviour in virtual environments. A convergence of progress in cognitive neuroscience and computer science should consider the powerful role of conscious and unconscious states as an interface between self and virtual worlds. In this chapter, we review the premise of...

A 16-year empirical assessment of anomalous human/machine interactions provides strong evidence that consciousness can add information to otherwise random digital strings. A parallel program of remote perception studies establishes the inverse process: the anomalous acquisition of information about distant physical targets. Remarkably, neither of these extraordinary capabilities shows any depen...

ARCOTREND index (NI) is based on studies of normal human brain electrical data. It uses an ordinary electrode to collect and analysis brain electrical signals immediately at any position of the head, to display the state of consciousness and depth of anesthesia of patients on the touch screen after automatic analysis and classification, so as to guide dose adjustment of anesthetics. NI may make...

In this study we describe a patient, TA, who developed a chronic amnesic-confabulatory syndrome, following rupture of a right internal carotid siphon aneurysm. Our aim was to elucidate as fully as possible the nature of TA's impairment and to test the hypothesis of confabulation as reflecting a dysfunction of Temporal Consciousness, i.e., to become aware of something as part of a personal past,...

Impairment in consciousness is common in acute stroke patients and is correlated with the clinical outcome after stroke. The underlying mechanism is not completely understood, with little known about brain activity and connectivity changes in acute stroke patients having impaired consciousness. In this study, we investigated changes in regional brain activity and brain networks of consciousness...
