Document Summary

Consciousness: a person"s awareness of feelings, sensations and thoughts at a given moment. Daydreaming a form of consciousness involving fantasies, usually spontaneous, that occur while person is awake. Anesthetic depth- anesthetic awareness, feel pain even under anesthesia. Brain injured patients and consciousness two levels of consciousness: wakefulness: reticular formation (neural networks in brainstem, awareness: thalamus and central cortex. If someone is on a persistent vegetative state damage to thalamus it is the part of the brain that produces wakefulness without awareness. Infradian rhythms: longer rhythms. released in the night. Chronobiology investigates and applies information about biological rhythms. Body temperature- another circadian rhythm goes down during sleep; related to level of alertness and sleep wake cycle. Jet lag- temporary maladjustment that occurs when a change of time zones causes biological rhythms to be out of step with local time: gaining time phase delay, the circadian rhythms are controlled by suprachiasmatic nucleus (scn)
