Behavioral endocrinology

{{Main|Neuroendocrinology}}

The neuroendocrine system is an integrated system composed of neurons, glands and non-endocrine tissues, and the hormones and neurochemicals they produce and receive collectively regulate physiological or behavioral state.{{Citation|last=Levine|first=Jon E.|title=Chapter 1 - An Introduction to Neuroendocrine Systems|date=2012-01-01|url=http://www.sciencedirect.com/science/article/pii/B9780123750976100010|work=Handbook of Neuroendocrinology|pages=3–19|editor-last=Fink|editor-first=George|publisher=Academic Press|isbn=9780123750976|access-date=2019-10-07|editor2-last=Pfaff|editor2-first=Donald W.|editor3-last=Levine|editor3-first=Jon E.}}

{{Main|Hypothalamus}}

The hypothalamus is a distinct part of the brain that is made up of neurons and its main purpose is to maintain homeostasis.{{Citation|last=Hennig|first=J.|title=Hypothalamus|date=2001-01-01|url=http://www.sciencedirect.com/science/article/pii/B0080430767034689|encyclopedia=International Encyclopedia of the Social & Behavioral Sciences|pages=7113–7118|editor-last=Smelser|editor-first=Neil J.|publisher=Pergamon|isbn=9780080430768|access-date=2019-10-07|editor2-last=Baltes|editor2-first=Paul B.}} The hypothalamus also plays an important part in survival of the individual by integrating the interactions between hormonal and behavioral processes, such as, eating behavior and aggressive behavior.

{{Main|Pituitary gland}}

The pituitary gland located in the brain is a major system in neuroendocrine system because the secretion of hormones from the anterior pituitary is directly regulated by the central nervous system.{{Citation|last=Goodman|first=H. Maurice|title=Chapter 2 - Pituitary Gland|date=2009-01-01|url=http://www.sciencedirect.com/science/article/pii/B9780123739759000021|work=Basic Medical Endocrinology (Fourth Edition)|pages=29–42|editor-last=Goodman|editor-first=H. Maurice|publisher=Academic Press|isbn=9780123739759|access-date=2019-10-07}}

Social behavior, reproductive behavior, moods, feelings, attitudes, development and survival are affected by the neuroendocrine system and studied in the field of behavioral endocrinology.{{Cite book |last=Welling |first=Lisa L.

{{Main|Cortisol}}

See the Cortisol: Memory and Stress sections for more information on how cortisol has been found to affect behavior.{{cn|date=July 2024}}

{{Main|Sex hormone}}

Testosterone is secreted by the testicles of males and the ovaries of females, although small amounts are also secreted by the adrenal glands. It is the principal male sex hormone and an anabolic steroid. See Testosterone: Aggression and criminality and Testosterone: Brain for more information on how testosterone effects behavior.{{cn|date=July 2024}}

Estrogens, together, make up a group of primary female sex hormones synthesized in the ovaries. See Estrogen: Brain and behavior for more on the role of estrogen in behavioral endocrinology.

Thyroid hormones are responsible for controlling metabolism, nervous system, body temperature and development of several organ systems such as the reproductive system.

{{Main|Endocrine disease}}

Hyperthyroidism and hypothyroidism are the two major dysfunctions associated to behavioral and brain chemistry changes due to the imbalances in the thyroid hormones, triiodothyronine (T₃) and thyroxine (T₄).{{Citation|last1=Bauer|first1=Michael|title=Thyroid Hormone, Brain, and Behavior|date=2002|work=Hormones, Brain and Behavior|pages=239–264|publisher=Elsevier|doi=10.1016/b978-012532104-4/50023-8|isbn=9780125321044|last2=Whybrow|first2=Peter C.}}

Behavioral endocrinology has roots in ethology and is also seen as a combination of endocrinology and psychology. Like ethology, behavioral endocrinology focuses on behavior on the level of the whole organism. The invention of radioimmunoassay techniques revolutionized behavioral endocrinology, allowing scientists to see and quantify hormones. The field historically resists reductionist thinking and focuses on the physiological aspects of behavior.{{Cite journal|last=Marler|first=Peter|date=2005-04-01|title=Ethology and the origins of behavioral endocrinology|journal=Hormones and Behavior|volume=47|issue=4|pages=493–502|doi=10.1016/j.yhbeh.2005.01.002|issn=0018-506X|pmid=15777816|s2cid=16538119 }}
