Ivanka Savic Berglund (born 1953) is a Serbian-Swedish neuroscientist, a professor of neurology and chief physician at the Karolinska Institute in Sweden, and an adjunct professor in the neurology department at the University of California, Los Angeles (UCLA). [1] [2] [3] [4] Savic is best known for her neurophysiology and neuroimaging research relating to epilepsy, sex differences, sexual orientation, gender identity, brain processing of odors and pheromones, and the effects of chronic stress on the brain. Savic is a co-founder of the Stockholm Brain Institute and the editor of several medical books. [1]

Education and career

Savic was born in Belgrade, Serbia in 1953 to a family of high ranking military officers and academics. She began her medical studies at Uppsala University in Sweden, graduated as a doctor at Karolinska Institute (KI) in 1978 and became a certified doctor in 1980. [1] In 1984 she became a specialist in neurology and in 1991 in clinical neurophysiology. Savic received her PhD doctorate in 1992. In 1994–1996, she worked in a post doctoral position with Jerome Engel at the University of California, Los Angeles (UCLA), which became a long standing collaboration.

In 1996, Savic returned to research at the Karolinska Institute, where she became an associate professor in 1999. The same year, she became chief physician at Karolinska University Hospital Huddinge. In 1997–2003, she had a research assistant and a research position at the Swedish Research Council. In 2003–2009, she held an "elite position" as a research group leader at the Karolinska Institute. She was appointed professor of neurology in 2013 with a special focus on gender differences at Karolinska Institute, combined with a position as chief physician at Karolinska University Hospital. [1] In 2016 she became an adjunct professor at UCLA. [5]

Savic is a co-founder and member of the Stockholm Brain Institute's executive committee. [1] She is the editor and co-editor of two educational medical books on sex differences in the human brain, their underlying mechanisms and clinical implications. [6] [7]

Epilepsy

During her doctoral thesis, Savic investigated the GABA benzodiazepine receptor's role in temporal lobe epilepsy and helped to develop a new and internationally used method to pre-surgically diagnose the epileptogenic region. [2] [1]

Pheromone and odour processing

Savic was the first scientist to show that humans process pheromone stimuli in the brain, differently from other odours, and in a sexually differentiated manner. [8] [1]

Sexual orientation

Savic has carried out neuroimaging research to compare the brain structure of homosexual and heterosexual men and women. In 2008 Savic found both male and female homosexual persons in her samples had brain activation with pheromones, and amygdala's connections which resembled those of the opposite sex, i.e. gay men had a female-typical pattern, while lesbians had male-typical pattern. [4] [9] [10] Neuroscientist Simon LeVay included her research in his book Gay, Straight, and the Reason Why, and discusses its relevance to other neuroscience research related to sexual orientation. [4] : 112 

Savic and her colleagues also carried out research on brain activity in gay and straight men in response to "putative human pheromones". [4] : 115–116 

Later research Savic carried out in 2018 and 2019 suggests that male homosexuality may be related to cerebral midline structures of the brain, which were not found in her sample of heterosexual females or males. [11] [12] [13]

Gender identity

Savic has also studied the brains of transgender people. Her research suggests that transgender men and women have weaker connections between the two areas of the brain that process the perception of self and one's own body compared to cisgender persons. Savic has said these connections seem to improve after the person receives cross-hormone treatment. [3] Savic has co-authored papers with the dutch neuroscientist Dick Swaab on the brain structure of transsexual and transgender people. [14]

Lesbian, gay, bisexual, transgender and queer (LGBTQ) movements are social movements that advocate for LGBTQ people in society. Although there is not a primary or an overarching central organization that represents all LGBTQ people and their interests, numerous LGBTQ rights organizations are active worldwide. The first organization to promote LGBTQ rights was the Scientific-Humanitarian Committee, founded in 1897 in Berlin.

<span class="mw-page-title-main">Heterosexuality</span> Attraction between people of the opposite sex or gender

Heterosexuality is romantic attraction, sexual attraction or sexual behavior between people of the opposite sex or gender. As a sexual orientation, heterosexuality is "an enduring pattern of emotional, romantic, and/or sexual attractions" to people of the opposite sex. It "also refers to a person's sense of identity based on those attractions, related behaviors, and membership in a community of others who share those attractions." Someone who is heterosexual is commonly referred to as straight.

<span class="mw-page-title-main">Sexual orientation</span> Pattern of romantic or sexual attraction

Sexual orientation is an enduring personal pattern of romantic attraction or sexual attraction to persons of the opposite sex or gender, the same sex or gender, or to both sexes or more than one gender. Patterns are generally categorized under heterosexuality, homosexuality, and bisexuality, while asexuality is sometimes identified as the fourth category.

<span class="mw-page-title-main">Biology and sexual orientation</span> Field of sexual orientation research

The relationship between biology and sexual orientation is a subject of on-going research. While scientists do not know the exact cause of sexual orientation, they theorize that it is caused by a complex interplay of genetic, hormonal, and environmental influences. However, evidence is weak for hypotheses that the post-natal social environment impacts sexual orientation, especially for males.

<span class="mw-page-title-main">Homosexuality and psychology</span> Homosexuality as studied by the field of psychology

The field of psychology has extensively studied homosexuality as a human sexual orientation. The American Psychiatric Association listed homosexuality in the DSM-I in 1952 as a "sociopathic personality disturbance," but that classification came under scrutiny in research funded by the National Institute of Mental Health. That research and subsequent studies consistently failed to produce any empirical or scientific basis for regarding homosexuality as anything other than a natural and normal sexual orientation that is a healthy and positive expression of human sexuality. As a result of this scientific research, the American Psychiatric Association removed homosexuality from the DSM-II in 1973. Upon a thorough review of the scientific data, the American Psychological Association followed in 1975 and also called on all mental health professionals to take the lead in "removing the stigma of mental illness that has long been associated" with homosexuality. In 1993, the National Association of Social Workers adopted the same position as the American Psychiatric Association and the American Psychological Association, in recognition of scientific evidence. The World Health Organization, which listed homosexuality in the ICD-9 in 1977, removed homosexuality from the ICD-10 which was endorsed by the 43rd World Health Assembly on 17 May 1990.

<span class="mw-page-title-main">Demographics of sexual orientation</span> Prevalence of different types of sexual orientation

Obtaining precise numbers on the demographics of sexual orientation is difficult for a variety of reasons, including the nature of the research questions. Most of the studies on sexual orientation rely on self-reported data, which may pose challenges to researchers because of the subject matter's sensitivity. The studies tend to pose two sets of questions. One set examines self-report data of same-sex sexual experiences and attractions, while the other set examines self-report data of personal identification as homosexual or bisexual. Overall, fewer research subjects identify as homosexual or bisexual than report having had sexual experiences or attraction to a person of the same sex. Survey type, questions and survey setting may affect the respondents' answers.

"Gay bomb" is an informal term referring to a hypothetical non-lethal psychochemical weapon about which the United States Air Force speculated. The unconventional idea involved the potential dispersion of sex pheromones among enemy forces, with the intent of generating mutual sexual attraction among them, causing mass confusion and panic.

A sexual minority is a demographic whose sexual identity, orientation or practices differ from the majority of the surrounding society. Primarily used to refer to lesbian, gay, bisexual, or non-heterosexual individuals, it can also refer to transgender, non-binary or intersex individuals.

<span class="mw-page-title-main">Androphilia and gynephilia</span> Sexual orientation to men or women

In behavioral science, androphilia and gynephilia are sexual orientations: Androphilia is sexual attraction to men and/or masculinity; gynephilia is sexual attraction to women and/or femininity. Ambiphilia describes the combination of both androphilia and gynephilia in a given individual, or bisexuality. The terms offer an alternative to a gender binary homosexual and heterosexual conceptualization of sexuality.

INAH-3 is the short form for the third interstitial nucleus of the anterior hypothalamus, and is the sexually dimorphic nucleus of humans. The INAH-3 is significantly larger in males than in females regardless of age and larger in heterosexual males than in homosexual males and heterosexual females. Homologs of the INAH-3 have been found to play a direct role in sexual behavior in quails, rhesus macaques, sheep, rats, mice, and ferrets.

<span class="mw-page-title-main">LGBTQ rights in Sweden</span>

Lesbian, gay, bisexual, transgender, and queer (LGBTQ) rights in Sweden are regarded as some of the most progressive in Europe and the world. Same-sex sexual activity was legalized in 1944 and the age of consent was equalized to that of heterosexual activity in 1972. Sweden also became the first country in the world to allow transgender people to change their legal gender post-sex reassignment surgery in 1972, whilst transvestism was declassified as an illness in 2009. Legislation allowing legal gender changes without hormone replacement therapy and sex reassignment surgery was passed in 2013.

The American-Canadian sexologist Ray Blanchard proposed a psychological typology of gender dysphoria, transsexualism, and fetishistic transvestism in a series of academic papers through the 1980s and 1990s. Building on the work of earlier researchers, including his colleague Kurt Freund, Blanchard categorized trans women into two groups: homosexual transsexuals who are attracted exclusively to men and are feminine in both behavior and appearance; and autogynephilic transsexuals who experience sexual arousal at the idea of having a female body. Blanchard and his supporters argue that the typology explains differences between the two groups in childhood gender nonconformity, sexual orientation, history of sexual fetishism, and age of transition.

Gender incongruence is the state of having a gender identity that does not correspond to one's sex assigned at birth. This is experienced by people who identify as transgender or transsexual, and often results in gender dysphoria. The causes of gender incongruence have been studied for decades.

Sexual orientation is an enduring pattern of romantic or sexual attraction to persons of the opposite sex or gender, the same sex or gender, or to both sexes or more than one gender, or none of the aforementioned at all. The ultimate causes and mechanisms of sexual orientation development in humans remain unclear and many theories are speculative and controversial. However, advances in neuroscience explain and illustrate characteristics linked to sexual orientation. Studies have explored structural neural-correlates, functional and/or cognitive relationships, and developmental theories relating to sexual orientation in humans.

The demographics of sexual orientation and gender identity in the United States have been studied in the social sciences in recent decades. A 2023 Gallup poll concluded that 7.6% of adult Americans identified as LGBTQ+. A different survey in 2016, from the Williams Institute, estimated that 0.6% of U.S. adults identify as transgender. As of 2022, estimates for the total percentage of U.S. adults that are transgender or nonbinary range from 0.5% to 1.6%. Additionally, a Pew Research survey from 2022 found that approximately 5% of young adults in the U.S. say their gender is different from their sex assigned at birth.

The Sexual Brain is a 1993 book about brain mechanisms involved in sexual behavior and feelings, and related topics such as sexual orientation, by the neuroscientist Simon LeVay. The book was praised as a well-written work on science. However, some reviewers pointed out factual errors, and stated that LeVay failed to prove that homosexuality has a biological basis.

Conspiracy theories alleging that governments are using endocrine disrupting chemical pollutants in the water supply to create an alleged increase in the gay, bisexual or transgender population were popularized in the 2010s. Most notably, American conspiracy theorist Alex Jones cited research on the effects of atrazine on frogs, which can induce spontaneous sex change or hermaphroditism, claiming that the federal government of the United States was "putting chemicals in the water that turn the friggin’ frogs gay" as part of a "chemical warfare operation" or "gay bomb" to increase homosexuality and suppress birth rates. However, frogs have the ability to spontaneously change sex in non-polluted waterways in response to changes in temperature.
