Research into dreams includes exploration of the mechanisms of dreaming, the influences on dreaming, and disorders linked to dreaming. Work in oneirology overlaps with neurology and can vary from quantifying dreams to analyzing brain waves during dreaming, to studying the effects of drugs and neurotransmitters on sleeping or dreaming. Though ...
This includes the activation synthesis theory—the theory that dreams result from brain stem activation during REM sleep; the continual activation theory—the theory that dreaming is a result of activation and synthesis but dreams and REM sleep are controlled by different structures in the brain; and dreams as excitations of long-term memory ...
Their model posits that dreams are actively generated by the brain stem and then passively synthesized by the forebrain. That is, the cholinergic activation that occurs in any forebrain areas (via transmission from brain stem) results in attempts by the brain's cognitive areas to enforce sense or structure onto meaningless activation.

The effects of the brain activity can interfere with the REM (rapid eye movement) part of sleep, where the majority of dreams and nightmares occur, which is around 90 minutes into sleep. REM is ...
Some dreams even enable the body to express feverish or sickly states, and herald future biological disorders. Dreams can in fact have somatic causes, a fact which, as Jung points out, has long been recognized by traditional and shamanic medicine and, more recently, by experimental psychology. Similarly, certain physical and environmental ...
(B) The pigtail catheter is placed in the dilated calyx. The tube in (A) and the pigtail in (B) are marked with white arrows. [1] A nephrostomy or percutaneous nephrostomy is an artificial opening created between the kidney and the skin which allows for the urinary diversion directly from the upper part of the urinary system (renal pelvis).

Unlike the waking state, the brain cannot recognize its own condition; that it is in the midst of the dream and is not the same as the real world. [1] The brain has a single-minded state of primary consciousness during dreaming, which allows the brain to reach greater perception and awareness of a single scenario out of images and dreams. [1]
The main dopaminergic pathways of the human brain. Dopaminergic pathways (dopamine pathways, dopaminergic projections) in the human brain are involved in both physiological and behavioral processes including movement, cognition, executive functions, reward, motivation, and neuroendocrine control.
