| | HYPOTHALAMUS |
 | | The hypothalamus plays a major integrative role in the control of maternal and reproductive behavior, including sexual development, and differentiation, as well as sexual behavior. | | | Estradiol elicits positive feedback by acting at the level of the hypothalamus to increase GnRH release and at the level of the pituitary to increase gonadotrope sensitivity to GnRH. | | | These areas project both caudally to the spinal cord and rostrally to the hypothalamus, thalamus and cortex. |

| | The suprachiasmatic nucleus of the hypothalamus is the seat of a biological clock that keeps near 24-hr time and generates the signals that time diverse aspects of metabolism, physiology, and behavior and integrates them with respect the daily cycle of light and darkness in the external world. | | | The hypothalamus plays a vital role in many body functions, including emotional behavior and the regulation of water balance, temperature, feeding behavior, sleep-wakefulness cycle, autonomic activities, and circadian rhythms. | | | The posterior hypothalamus is responsible for heat conservation. |

| | Hypothalamus Over-Activation |
| | The Hypothalamus is situated in the mid-brain, from which place it controls practically every organ in the body, mainly through the Endocrine system. | | | The key function of the Hypothalamus is to coordinate the actions of the Nervous system, the Muscles, the Gut and the Immune system, along with the body's energy reserves, so that a balance can be maintained. | | | A dysfunctional Hypothalamus ceases to respond appropriately to feedback from the body regarding its exhausted state. |

| | Karen Skinner, Ph.D. Jonathan Pollock, Ph.D. On July 10, 2001, NIDA sponsored a workshop entitled "The Hypothalamus and Addiction." The purpose of the meeting was to discuss the extent to which gene expression studies in the hypothalamus may inform biological studies on the anatomy and function of the hypothalamus in varying "states" including addiction. | | | A wide range of existing and emerging tools and techniques may be applied to studies of functional neuroanatomy of the hypothalamus. | | | A pilot study should be initiated to explore approaches to the development of such a knowledge base. |

| | Last year, postdoctoral fellow Elias and her colleagues identified the pathway between the two parts of the hypothalamus that apparently linked leptin to eating. | | | In the past several years, the researchers in Elmquist's lab have combined genetic techniques with neuroanatomic methods to tease out the details of the neural pathways linking leptin to eating behavior. | | | In these classic experiments with rats, lesions in one part of the hypothalamus created massively obese rats. |

| | The hypothalamus, which together with the thalamus makes up the section of the forebrain called the diencephalon, is involved in such aspects of behavior as motivation, emotion, eating, drinking, and sexuality. | | | With neurons firing on a 24- or 25-hour cycle, it determines the periods of greatest alertness-whether one is "morning person" or a "night person." Pathways from the SCN to the eyes connect its circadian rhythms to external cycles of light and dark. | | | From the SCN, signals reach areas of the hindbrain that regulate sleep and wakefulness. |
