Information:  - The Erotes are a collective of winged gods associated with love and sex in Greek mythology. They are part of Aphrodite's retinue. "Erotes" (Greek ) is the plural of "Eros" ("Love, Desire"), who as a singular deity has a more complex mythology.  - Psychoanalytic theory is the theory of personality organization and the dynamics of personality development that guides psychoanalysis, a clinical method for treating psychopathology. First laid out by Sigmund Freud in the late 19th century, psychoanalytic theory has undergone many refinements since his work. Psychoanalytic theory came to full prominence in the last third of the twentieth century as part of the flow of critical discourse regarding psychological treatments after the 1960s, long after Freud's death in 1939, and its validity is now widely disputed or rejected. Freud had ceased his analysis of the brain and his physiological studies and shifted his focus to the study of the mind and the related psychological attributes making up the mind, and on treatment using free association and the phenomena of transference. His study emphasized the recognition of childhood events that could influence the mental functioning of adults. His examination of the genetic and then the developmental aspects gave the psychoanalytic theory its characteristics. Starting with his publication of "The Interpretation of Dreams" in 1899, his theories began to gain prominence.  - Psychopathology is the scientific study of mental disorders, including efforts to understand their genetic, biological, psychological, and social causes; effective classification schemes (nosology); course across all stages of development; manifestations; and treatment. The term may also refer to the manifestation of behaviors that indicate the presence of a mental disorder.  - Sigmund Freud ( born Sigismund Schlomo Freud; 6 May 1856  23 September 1939) was an Austrian neurologist and the founder of psychoanalysis, a clinical method for treating psychopathology through dialogue between a patient and a psychoanalyst. Freud was born to Galician Jewish parents in the Moravian town of Freiberg, in the Austro-Hungarian Empire. He qualified as a doctor of medicine in 1881 at the University of Vienna. Upon completing his habilitation in 1885, he was appointed a docent in neuropathology and became an affiliated professor in 1902. Freud lived and worked in Vienna, having set up his clinical practice there in 1886. In 1938 Freud left Austria to escape the Nazis. He died in exile in the United Kingdom in 1939.  - Aphrodite (; Greek: ("Afrodíti")) is the Greek goddess of love, beauty, pleasure, and procreation. She is identified with the planet Venus, and her Roman equivalent is the goddess .  - In classical mythology, Cupid (Latin Cupido, meaning "desire") is the god of desire, erotic love, attraction and affection. He is often portrayed as the son of the love goddess Venus and the war god Mars, and is known in Latin also as "Amor" ("Love"). His Greek counterpart is Eros.  - Testosterone is the primary male sex hormone and an anabolic steroid. In men, testosterone plays a key role in the development of male reproductive tissues such as the testis and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair. In addition, testosterone is essential for health and well-being, and for the prevention of osteoporosis. Insufficient levels of testosterone in men may lead to abnormalities including frailty and bone loss.  - Greek mythology is the body of myths and teachings that belong to the ancient Greeks, concerning their gods and heroes, the nature of the world, and the origins and significance of their own cult and ritual practices. It was a part of the religion in ancient Greece. Modern scholars refer to and study the myths in an attempt to shed light on the religious and political institutions of Ancient Greece and its civilization, and to gain understanding of the nature of myth-making itself.  - The University of Vienna is a public university located in Vienna, Austria. It was founded by Duke Rudolph IV in 1365 and is one of the oldest universities in the German-speaking world. With its long and rich history, the University of Vienna has developed into one of the biggest universities in Europe, and also one of the most renowned, especially in the Humanities. It is associated with 15 Nobel prize winners and has been the academic home of a large number of figures both of historical and academic importance.  - Psychoanalysis is a set of theories and therapeutic techniques related to the study of the unconscious mind, which together form a method of treatment for mental-health disorders. The discipline was established in the early 1890s by Austrian neurologist Sigmund Freud and stemmed partly from the clinical work of Josef Breuer and others.  - In Greek mythology, Thanatos ([] "Death", from  "thnsk" "to die, be dying") was the personification of death. He was a minor figure in Greek mythology, often referred to, but rarely appearing in person.  - Vienna is the capital and largest city of Austria and one of the nine states of Austria. Vienna is Austria's primary city, with a population of about 1.8 million (2.6 million within the metropolitan area, nearly one third of Austria's population), and its cultural, economic, and political centre. It is the 7th-largest city by population within city limits in the European Union. Until the beginning of the 20th century, it was the largest German-speaking city in the world, and before the splitting of the Austro-Hungarian Empire in World War I, the city had 2 million inhabitants. Today, it has the second largest number of German speakers after Berlin. Vienna is host to many major international organizations, including the United Nations and OPEC. The city is located in the eastern part of Austria and is close to the borders of the Czech Republic, Slovakia, and Hungary. These regions work together in a European Centrope border region. Along with nearby Bratislava, Vienna forms a metropolitan region with 3 million inhabitants. In 2001, the city centre was designated a UNESCO World Heritage Site.  - Beyond the Pleasure Principle ( German : Jenseits des Lustprinzips ) is a 1920 essay by Sigmund Freud that marks a major turning point in his theoretical approach . Previously , Freud attributed most human behavior to the sexual instinct ( Eros or libido ) . With this essay , Freud went `` beyond '' the simple pleasure principle , developing his theory of drives with the addition of the death drive ( s ) ( Todestrieb ( e ) ) ( often referred to as `` Thanatos '' ) .  - Hypersexuality is a clinical diagnosis used by mental healthcare researchers and providers to describe extremely frequent or suddenly increased sexual urges or sexual activity. The terms nymphomania and satyriasis were once used to describe the condition, in women and men respectively, but are no longer in general medical use, although the former is still used colloquially.  - Moravia  is a historical country in the Czech Republic (forming its eastern part) and one of the historical Czech lands, together with Bohemia and Czech Silesia. The medieval and early modern Margraviate of Moravia was a crown land of the Lands of the Bohemian Crown (from 1348 to 1918), an imperial state of the Holy Roman Empire (1004 to 1806), later a crown land of the Austrian Empire (1804 to 1867) and briefly also one of 17 former crown lands of the Cisleithanian part of the Austro-Hungarian Empire from 1867 to 1918. During the early 20th century, Moravia was one of the five lands of Czechoslovakia from 1918 to 1928; it was then merged with Czech Silesia, and eventually dissolved by abolition of the land system in 1949.  - The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union.  - In Greek mythology, Eros (or ,  "Desire") was the Greek god of love. His Roman counterpart was Cupid ("desire"). Some myths make him a primordial god, while in other myths, he is the son of Aphrodite. He was one of the winged love gods, Erotes.  - Puberty is the process of physical changes through which a child's body matures into an adult body capable of sexual reproduction. It is initiated by hormonal signals from the brain to the gonads: the ovaries in a girl, the testes in a boy. In response to the signals, the gonads produce hormones that stimulate libido and the growth, function, and transformation of the brain, bones, muscle, blood, skin, hair, breasts, and sex organs. Physical growthheight and weightaccelerates in the first half of puberty and is completed when an adult body has been developed. Until the maturation of their reproductive capabilities, the pre-pubertal physical differences between boys and girls are the external sex organs.  - In classical Freudian psychoanalytic theory, the death drive is the drive towards death and self-destruction. It was originally proposed by Sabina Spielrein in her paper "Destruction as the Cause of Coming Into Being" (""Die Destruktion als Ursache des Werdens"") which was then taken up by Sigmund Freud in 1920 in "Beyond the Pleasure Principle." This concept has been translated as, "opposition between the ego or death instincts and the sexual or life instincts". In "Pleasure Principle", Freud used the plural "death drives" ("Todestriebe") much more frequently than in the singular.  - Neuropathology is the study of disease of nervous system tissue, usually in the form of either small surgical biopsies or whole-body autopsies. Neuropathology is a subspecialty of anatomic pathology, neurology, and neurosurgery. It should not be confused with neuropathy, which refers to disorders of the nerves themselves (usually in the peripheral nervous system).  - Libido, colloquially known as sex drive, is a person's overall sexual drive or desire for sexual activity. Sex drive is influenced by biological, psychological and social factors. Biologically, the sex hormones and associated neurotransmitters that act upon the nucleus accumbens (primarily testosterone and dopamine, respectively) regulate libido in humans. Social factors, such as work and family, and internal psychological factors, like personality and stress, can affect libido. Sex drive can also be affected by medical conditions, medications, lifestyle and relationship issues, and age (e.g., puberty). A person who has extremely frequent or a suddenly increased sex drive may be experiencing hypersexuality, while the opposite condition is hyposexuality.  - Instinct or innate behavior is the inherent inclination of a living organism towards a particular complex behavior. The simplest example of an instinctive behavior is a fixed action pattern (FAP), in which a very short to medium length sequence of actions, without variation, are carried out in response to a clearly defined stimulus.
