Exam Questions and Answers
Alpha brain waves --- correct precise answer ---occur when awake &
resting w/ eyes closed
Beta brain waves --- correct precise answer ---occur w/ eyes open
performing mental tasks

sleep
,Sleep --- correct precise answer ---temporary state of
unconsciousness; controlled by hypothalamus, reticular formation
thalamus & cerebral cortex
Sleep paralysis --- correct precise answer ---inhibition of muscular
activity
Suprachiasmatic nucleus --- correct precise answer ---acts as a
biological clock to set circadian rhythym
Restorative effect (sleep) --- correct precise answer ---Brain
glycogen levels increase
memories strengthened (synoptic connections reinforced or
eliminated)
4 stages of Non-REM sleep --- correct precise answer ---(occurring
in the first 30-45 minutes of sleep)
#1 is a drifting sensation (would claim was not sleeping)
#2 still easily aroused
#3 [reached in 20 mins] vital signs change: BP, pulse & breathing
rates drop
#4 is deep sleep, difficult to arouse
REM sleep occurs about ___ times a night --- correct precise answer
---five
,REM sleep --- correct precise answer ---rapid eye movements under
the eyelids, vital signs increase, EEG resembles awake person,

Anterograde amnesia --- correct precise answer ---Can not store
new data
Retrograde amnesia --- correct precise answer ---can not remember
old data
Lesion- Hioppocampus --- correct precise answer ---causes inability
to form new memories
Emotion --- correct precise answer ---form in hypothalamus &
amygdala
-artificial stimulation produces fear, anger, pleasure, love, parental
affection, etc.
___ ___ controls how emotions are expressed (seat of judgement) --
- correct precise answer ---Prefrontal Cortex
Somesthetic Sensation --- correct precise answer ---comes from
receptors widely distributed throughout the body (touch, pain,
pressure, stretch, movement, heat, cold)
somatosensory area is postcentral gyrus
