a) unusual symptoms of tiredness and irritability that follow periods of rem sleep deprivation.
b) tendency for rem sleep to increase following rem sleep deprivation.
c) replacement of rem sleep with nrem sleep.
d) tendency for rem sleep periods to become increasingly longer and more frequent as a normal night of sleep progresses.

a) frontal association area.
b) angular gyrus.
c) hypothalamus.
d) motor cortex.
e) reticular formation.

Explanation:

1. The limbic system is involved in emotions, so it influences the emotional tone of dreams during REM sleep.
2. The human sleep cycle repeats approximately every 90 minutes.
3. Electroencephalogram (EEG) can be used to map brain areas for specific activities like movement or speech.
4. REM rebound is the tendency for REM sleep to increase after REM sleep deprivation.
5. The motor cortex at the rear of the frontal lobes controls voluntary movements.

Answer:

1. E. limbic system
2. A. 90 minutes
3. E. electroencephalogram (EEG)
4. B. tendency for REM sleep to increase following REM sleep deprivation
5. D. motor cortex
