Active Learning 1 Flashcards
2 parts of consciousness
wakeful, aware
unresponsive wakefulness =
vegetative state
coma
unresponsive to internal or external stimuli (may have preserved spinal reflexes)
unarousable
NO spontaneous eye opening
unresponsive to internal or external stimuli (may have preserved spinal reflexes)
unarousable
NO spontaneous eye opening
coma
sleep-wake cycles, opens eyes
unresponsive to internal/external stimuli
not aware of self or others
may smile/grimace, reflexively grip hand
No thoughts memories emotions or intentions
Vegetative state (unresponsive wakefulness)
Vegetative state (unresponsive wakefulness)
sleep-wake cycles, opens eyes
unresponsive to internal/external stimuli
not aware of self or others
may smile/grimace, reflexively grip hand
No thoughts memories emotions or intentions
Some sleep-wake cycles
Incomplete awareness
ie alcohol, head injury, metabolic derangements
Minimally conscious state
Sleep wake cycles, intact awareness quadriplegia, sensory loss, anarthria conscious but unable to interact with external world (may be able to blink, look up or down) Brainstem lesion (bilateral ventral pons)
Locked-in Syndrome
Locked-in Syndrome
Sleep wake cycles, intact awareness quadriplegia, sensory loss, anarthria conscious but unable to interact with external world (may be able to blink, look up or down) Brainstem lesion (bilateral ventral pons)
CNS = (4)
forebrain, brain stem, spinal cord, cerebellum
Forebrain = (3)
Cerebral cortex
Basal ganglia
Thalamus
Function Forebrain

Motor control center
Executive function
Cerebral cortex - frontal lobe
Somatosensory processing
Cerebral cortex - parietal lobe
Auditory processing
New memory formation
Temporal lobe (cerebral cortex)
