Dreams
Beginning of paper
Theories attempting to explain the origin and functions of REM sleep
include: (1) that REM sleep provides stimulation for the development of the
brain; (2) that it performs a chemical restoration function, since during REM
dreaming neuro-protein synthesis occurs along with the restoration of othe ....

.... by environmental stimuli during sleeping. Dreaming is
caused by internal biological process. Some researchers have proposed the
activation-synthesis hypothesis. Their neurological research indicates that
large brain cells in the primitive brain stem spontaneously fire about every 90
minutes, sending random stimuli to cortical areas of the BRAIN. As a
consequence, memory, sensory, muscle-control, and cognitive areas of the brain
are randomly stimulated, resulting in the higher cortical bra ....
