Flexi Says: The hypothalamus produces oxytocin hormone that are stored in the pituitary gland. In addition to influencing maternal behavior, oxytocin is involved in controlling aspects of circadian homeostasis such as a person's body temperature, activity level, and wakefulness at different times of the day. Most hormone feedback mechanisms involve negative feedback loops. Negative feedback keeps the concentration of a hormone within a narrow range. But oxytocin regulation involve positive feedback loops. The release of oxytocin feeds back to increase more oxytocin production and release.
