Reduced duration of sleep, as well as an increase in time spent awake, are factors that highly contribute to the risk of traffic collisions, the severity and fatality rates of which are on the same level as driving under the influence of alcohol, [53] [54] with 19 hours of wakefulness corresponding to a BAC of 0.05%, and 24 hours of wakefulness ...
Wakefulness is a daily recurring brain state and state of consciousness in which an individual is conscious and engages in coherent cognitive and behavioral responses to the external world. Being awake is the opposite of being asleep, in which most external inputs to the brain are excluded from neural processing. [1] [2] [3] [4]
Daniel Dennett's multiple drafts model of consciousness is a physicalist theory of consciousness based upon cognitivism, which views the mind in terms of information processing. The theory is described in depth in his book, Consciousness Explained , published in 1991.
The Structure of Intellect (SOI) model includes three axes (with 5-6 components per axis) that form a 3-dimensional cube; because each dimension is independent, there are 150 different potential aspects of intelligence. [35] Howard Gardner has written about several categories of intelligence, as opposed to a hierarchical model. [36]
Dehaene distinguishes conscious access from related but not identical ideas: "attention, wakefulness, vigilance, self-consciousness, and metacognition" (p. 25).. He introduces the project of measuring neural correlates of consciousness using paradigms like minimal contrasts of images, masking (subliminal stimuli), binocular rivalry, and attentional blink.
Representation of consciousness from the 17th century by Robert Fludd, an English Paracelsian physician. Consciousness, at its simplest, is awareness of internal and external existence. [1] However, its nature has led to millennia of analyses, explanations, and debate by philosophers, scientists, and theologians.
Models of consciousness are used to illustrate and aid in understanding and explaining distinctive aspects of consciousness. Sometimes the models are labeled theories of consciousness. Anil Seth defines such models as those that relate brain phenomena such as fast irregular electrical activity and widespread brain activation to properties of ...
This system of a sort of general activation of consciousness is called "arousal" or "wakefulness". [14] It is not necessarily accompanied by drowsiness. [16] Patients may be awake (not sleepy) yet still have a clouded consciousness (disorder of wakefulness). [17] Paradoxically, affected individuals say that they are "awake but, in another way ...
