chapter seven: states of consciousness Flashcards
what is consciousness
brain activity that is associated with experience, a constant thing
what are altered states
different states of consciousness depending on arousal (senses) and awareness (how aware of sense)
what consciousness do you have in a normal state
high arousal, high awareness
what consciousness do you have in a deep sleep
no arousal, no awareness
what consciousness do you have in a unresponsive wakefulness syndrome
high arousal, lower awareness
what does it mean to have unresponsive wakefulness syndrome
brain damage resulting in dead/little activity areas of the brain, base level comprehension or none at all
what consciousness do you have in a minimally conscious state
high arousal, some degree of awareness (can follow simple instructions)
what consciousness do you have in a locked-in syndrom
high arousal, high awareness
what happens with locked-in syndrome
appears unresponsive wakefulness, but fully aware of everything and unable to communicate traditionally. neuroimaging helps tells states apart
what is concentrative meditation
take out of current situation and place yourself elsewhere, deep focus on one thing
what is mindfullness
allow mind to wander but not respond to thoughts
how does sleep get triggered
signals from hypothalamus travel to pineal glands and produce melatonin
what is the purpose of melatonin

what is in charge of releasing these hormones
the hypothalamus
what are zeitgebers
clock that can be entertained by outside cues, awake to sleep cycle, external cues to tell one when cycle should end (the sun)
