Sleep cycles are primarily regulated by the brainstem, particularly the pons and medulla oblongata. The pons plays a crucial role in the regulation of REM (rapid eye movement) sleep, while the medulla is involved in the control of non-REM sleep. Together, these areas help coordinate the transition between different sleep stages and maintain the overall sleep-wake cycle.
The part of the brain that is primarily involved in sleep is the hypothalamus. Within the hypothalamus, there are specific regions that regulate sleep-wake cycles, such as the suprachiasmatic nucleus (SCN) and the ventrolateral preoptic nucleus (VLPO). These regions interact with other brain areas to control the timing and duration of sleep.
The pineal gland, located in the brain, produces the hormone melatonin which helps regulate sleep-wake cycles. Melatonin levels rise in the evening to promote sleep and decrease in the morning to help wake up.
hypothalamus
The hypothalamus is part of an organ - that being the brain. It isn't a gland, because it only secretes hormones locally. The pituitary is a gland because it secretes hormones into the bloodstream for distant effects.
hypothalamus - a region in the upper part of the brainstem that acts as a relay to the pituitary gland - it controls body temperature, circadian cycles, sleep, moods, hormonal body processes, hunger, and thirst. The hypothalamus is part of the limbic system and works with the pituitary gland.

The reticular formation is a network of neurons located in the brainstem. It is involved in regulating arousal, attention, and sleep-wake cycles.
The pineal gland synthesizes and secretes melatonin.

cerebral cortex
hypothalamus
The pons is the part of the brain that regulates body movement, attention, sleep, and alertness. The pons is the part of the brainstem that links the medulla oblongata and the thalamus.
The brainstem and hypothalamus regulate sleep-wake cycles. The pineal gland produces melatonin, a hormone that helps control sleep patterns. The thalamus also plays a role in promoting sleep by shutting off sensory information to the cerebral cortex.
Limbic system
hypothalamus
The part of the brain stem between the diencephalon and the pons is the midbrain, also known as the mesencephalon. It plays a crucial role in motor movement, auditory and visual processing, and regulating sleep-wake cycles. The midbrain contains structures such as the tectum, tegmentum, and substantia nigra.
