This painting depicts the pineal gland’s function through the serene imagery of a night sky. The moon represents the pineal gland, which secretes the hormone melatonin into the bloodstream during darkness. This process, symbolized by the molecules in the water, reduces alertness and facilitates sleep. The clouds, colored to resemble brain matter, underscore the gland’s location and connection to the brain. The artwork beautifully captures the natural rhythm of night and sleep, illustrating the harmonious interplay between the pineal gland and the body’s circadian rhythms.
