Answer 1

1. The correct answer is option B. The hippocampus is a small organ located within the brain's medial temporal lobe and forms an important part of the limbic system, the region that regulates emotions.

2. The correct answer is option A. Your brain's motor cortex is active during REM sleep, but your brainstem blocks its messages; This leaves your muscles relaxed, so much so that, except for an occasional finger, toe, or facial witch, you are essentially paralyzed.

3. The correct answer is option C. Delta waves are recorded with an electroencephalogram(EEG) and are usually associated with the deep stage 3 of NREM sleep and aid in characterizing the depth of sleep.
