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

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
