An out-of-body experience was repeatedly elicited during stimulation of the posterior part of the superior temporal gyrus on the right side in a patient in whom electrodes had been implanted to suppress tinnitus. Positron-emission tomographic scanning showed brain activation at the temporoparietal junction--more specifically, at the angular-supramarginal(More)
AIM To carry out a prospective study of cardiac arrest survivors to understand the qualitative features as well as incidence, and possible aetiology of near death experiences (NDEs) in this group of patients. METHOD All survivors of cardiac arrests during a 1 year period were interviewed within a week of their arrest, regarding memories of their(More)
Very little is known about the dying process and in particular the state of the human mind at the end of life. Cardiac arrest is the final step in the dying process irrespective of cause, and is also the closest physiological model of the dying process. Recent studies in cardiac arrest survivors have indicated that although the majority of cardiac arrest(More)
Epidemiological studies have demonstrated an association between different levels of air pollution and various health outcomes including mortality, exacerbation of asthma, chronic bronchitis, respiratory tract infections, ischaemic heart disease and stroke. Of the motor vehicle generated air pollutants, diesel exhaust particles account for a highly(More)
UNLABELLED To date there has been no reliable noninvasive real time monitoring available to determine cerebral perfusion during cardiac arrest. OBJECTIVES To investigate the feasibility of using a commercially available cerebral oximeter during in-hospital cardiac arrest, and determine whether this parameter predicts return of spontaneous circulation(More)
BACKGROUND Non-invasive monitoring of cerebral perfusion and oxygen delivery during cardiac arrest is not routinely utilized during cardiac arrest resuscitation. The objective of this study was to investigate the feasibility of using cerebral oximetry during cardiac arrest and to determine the relationship between regional cerebral oxygen saturation (rSO2)(More)
BACKGROUND Cardiac arrest (CA) survivors experience cognitive deficits including post-traumatic stress disorder (PTSD). It is unclear whether these are related to cognitive/mental experiences and awareness during CPR. Despite anecdotal reports the broad range of cognitive/mental experiences and awareness associated with CPR has not been systematically(More)
Cardiac arrest (CA) is a major cause of morbidity and mortality worldwide. Despite the use of conventional cardiopulmonary resuscitation (CPR), rates of return of spontaneous circulation and survival with minimal neurologic impairment remain low. Utilization of venoarterial extracorporeal membrane oxygenation (ECMO) for CA in adults is steadily increasing.(More)
Perhaps the biggest challenge facing neuroscience at the dawn of the 21st century is understanding the relationship between mind, consciousness and the brain. Editorials in recent years have highlighted the difficulties faced by cognitive neuroscience in attempting to answer questions regarding the nature, as well as the mechanism by which subjective(More)
Cardiac arrest is associated with a number of cognitive processes as well as long term psychological outcomes. Recent studies have indicated that approximately 10-20% of cardiac arrest survivors report cognitive processes, including the ability to recall specific details of their resuscitation from the period of cardiac arrest. In addition it has been(More)
