Despite the vast collection of literature on sexuality that has accumulated, human asexuality has been largely ignored. Asexuality is controversially considered a sexual orientation and people who identify as asexual are people who generally do not experience sexual attraction (Asexuality Visibility and Education Network, 2013). Although research on gender and sexual orientations has been conducted for centuries, the first real suggestion that there might be people who fall outside the spectrum of heterosexual and homosexual orientations came from Kinsey and colleagues in 1948. These individuals were placed in a separate category and were identified as having no erotic response to heterosexual or homosexual stimuli, but they were otherwise largely ignored by researchers (Kinsey, 1953). Later researchers associated asexuality with negative traits and pathologies, including depression and low self-esteem (Masters, Johnson, & Kolodny, 1986; Nuius, 1983). One problem with these studies, however, is that the researchers defined asexuality in a way that most current asexuals disagree with. For example, in a study by Bell and Weinberg (1978), references were made to asexual homosexuals who were simply hiding their homosexuality. Many asexuals, otherwise known as Aces, would struggle with this definition because homosexuality involves one type of sexual attraction: same-sex attraction. Because Aces generally feel no sexual attraction to anyone or anything, they should not be classified under the same label as a closeted homosexual. Another problem is that none of these studies actually focused on asexuality. Instead, they were added alongside and generally ignored. In 2004, Anthony Bogaert became the first researcher...... in the middle of an article ...... is a conflict between possible responses to a situation (Carter & van Veen, 2007) because the ACC caudal plays an important role when initiating goal-directed behaviors (Devinsky et al., 1995). Other areas sometimes activated include: the amydgala (Stoléru et al., 2011); the claustrum (Arnow et al., 2002; Stoléru et al., 2011); the orbitofrontal cortex (Stoléru et al., 2011); the hypothalamus (Redouté et al., 2002; Stoléru et al., 2011); the insula (Arnow et al., 2002; Moulier et al., 2006; Stoléru et al., 2011); the ventral striatum (Redouté et al., 2000; Stoléru et al., 2011); the cerebellum (Aalto et al., 2002; Ivry & Fiez, 2000; Stoléru et al., 2011). These areas are just a few of many areas that are activated in response to sexual stimuli, and they activate for various reasons and in response to various aspects of the stimuli..
