Dreaming and sleep are intertwined. Dreams occur mainly in the rapid-eye movement (REM) stage of sleep—when brain activity is high and resembles that of being awake. Because REM sleep is detectable in many species, and because research suggests that all mammals experience REM, [15] linking dreams to REM sleep has led to conjectures that ...
Furthermore, REM sleep was maintained. Remember that the pons is crucial for REM. Loss of dreaming only occurred when higher parts of the cerebral hemispheres were damaged. REM sleep is controlled by cholinergic activation in the pons. It is now believed that dreaming may be a dopaminergic process that occurs in limbic and frontal areas of the ...
