Observing Erotic Videos With Heterosexual Content Induces Different Cerebral Responses in Homosexual and Heterosexual Men

Cardiovascular, Endocrine, and Brain Activity Changes in Humans During Sexual Arousal Induced by Pornography vs. Masturbation; Updated Literature Guidelines

“…EEG monitoring of men during sexual arousal revealed a decrease in the absolute power (AP) of the alpha1 and alpha2 bands in the frontal dorsal lateral and parietal regions. In the heterosexual group, a reduced AP in the theta band was observed in the parietal regions during exposure to pornography, whereas a lower AP in the alpha1 band was observed solely in the frontopolar regions during the same stimuli (31). We observed remarkable activation of several key brain regions during the onset of sexual arousal in right-handed men.…”

Deep Learning in the Identification of Electroencephalogram Sources Associated with Sexual Orientation

“…One study found that heterosexual men rated the erotic video with higher general and sexual arousal than the homosexual participants. During observation of the neutral and erotic videos, both groups showed decreased amplitude of the alpha band in prefrontal and parietal cortices, indicating increased attention [50]. Another study revealed less suppression of the mu-rhythm, a specific central rhythm in the frequency range of alpha, in HoM as reaction to painful actions in comparison to heterosexual men [51].…”

“…However, at the group level, the extracted frequencies showed peaks in the beta and gamma range, not within the alpha band. Again, EEG beta activity has been associated with processing of erotic content in homosexual males [50]. Further, at both, the single subject level and at the group level, the areas with the most important weights for differentiation by the network were in the parietal cortex.…”

“…In applied psychology, EEG has been used quite diversely with many different research and practice purposes. Of particular importance are the assessment of human cognitive levels (Antonenko et al, 2010), exploring memory and emotional responses (Ramirez, & Vamvakousis, 2012;Schneider et al, 2020), brain characteristics and brain responses of people with psychological disorders (Huang et al, 2019) or children with disabilities (Ünal et al, 2019), mental health (Price, & Budzynski, 2009), sexual orientation (Amezcua-Gutiérrez et al, 2021), or learning tendency (Alwedaie et al, 2018). It can be seen that the application of EEG machines in experiments and practices in the fields of education and psychology are topics of great interest in the world.…”
