Phi; the symbol used for integrated information. Integrated information theory (IIT) proposes a mathematical model for the consciousness of a system. It comprises a framework ultimately intended to explain why some physical systems (such as human brains) are conscious, [1] and to be capable of providing a concrete inference about whether any physical system is conscious, to what degree, and ...
Pain stimulus is a technique used by medical personnel for assessing the consciousness level of a person who is not responding to normal interaction, voice commands or gentle physical stimuli (such as shaking of the shoulders). [1]
The duration of PTA in brain-injured patients is a useful predictor of the expected long-term effects of the injury, [36] along with the duration of loss of consciousness(LOC), and scores on the Glasgow Coma Scale (GCS), which measures degrees of consciousness, with higher scores indicating higher levels of functioning. A score of three ...
The Confusion Assessment Method (CAM) is a diagnostic tool developed to allow physicians and nurses to identify delirium in the healthcare setting. [1] It was designed to be brief (less than 5 minutes to perform) and based on criteria from the third edition-revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III-R).
The bispectral index has not been proven to measure the level of consciousness, independently of the cause of reduced consciousness (whether this be drugs, metabolic disease, hypothermia, head trauma, hypovolemia, natural sleep and so on).
Don't rely on bloviating pundits to tell you who'll prevail on Hollywood's big night. The Huffington Post crunched the stats on every Oscar nominee of the past 30 years to produce a scientific metric for predicting the winners at the 2013 Academy Awards.
Higher-order theories of consciousness propose that a mental state becomes conscious when it is the object of a higher-order representation, such as a thought or perception about that state. These theories argue that consciousness arises from a relationship between lower-order mental states and higher-order awareness of those states.
