In the biological theory of dreams, the three-dimensional AIM cube depicts all states of consciousness occupying a different space. Why does REM sleep occupy the lower front right portion of the cube?
A. Because it is active, external, and logicalB. Because it is non-active, external, and logicalC. Because it is highly active, internal, and looseD. Because it is non-active, internal, and loose

B) Because it is non-active, external, and logical

Explanation:

The Activation-Synthesis model of dreaming proposed by J. Allan Hobson and Robert McClarley in 1977, observes that the circuits in brain activates during REM sleep. The brain synthesizes and interprets internal activity like emotions, memories, experiences and sensations resulting in a dream.

Dreams are subjective interpretation of signals inside the brain during sleep.

Activation – The rate at  which the brain-mind can  process information.

Input Source – The extent  to which the brain-mind is  processing external vs  internal information.

Modulation – Shift in  balance between the  cholinergic and aminergic  system.

REM sleep occupies lower front right portion of the cube due to its non-active, external and logical nature.

>The Cortical activity  fluctuates from  mid-line to relatively  low levels as depicted in the diagram  

>Internal vs External  tends to be at mid-line

>Lastly, Modulation of  Aminergic vs  Cholinergic activity  hovers around  midline
