Typically, before and after surgical correction faces are assessed on still images by surgeons, orthodontists, the patients, and family members. We hypothesized that judgment of faces in motion and by naïve raters may closer reflect the impact on patients' real life, and the treatment impact on e.g. career chances. Therefore we assessed faces from dysgnathic patients (Class II, III and Laterogn...
Orotic acid has been demonstrated to be an effective precursor of the nucleic acid pyrimidines in animal tissues, both in viva (1, 2) and in vitro (3,4). It is a growth-stimulating factor for certain pyrimidineless mutants of microorganisms (5-8) and may be partially replaced by oxalacetic acid (9) or ureidosuccinic acid (10, 11) in some strains. The possibility that erotic acid, and, hence, th...
A fundamental question about the relationship between cognition and emotion concerns the neural substrate underlying emotional self-regulation. To address this issue, brain activation was measured in normal male subjects while they either responded in a normal manner to erotic film excerpts or voluntarily attempted to inhibit the sexual arousal induced by viewing erotic stimuli. Results demonst...
This article focuses on the organization of the erotic lives of young men who engage in homosexual practices. The reflections presented here are based on ethnographic research including observation in places of homosociability and interviews with young men in Rio de Janeiro reporting homosexual practices. By presenting erotic scenes pertaining to a homoerotic circuit and recording the sexual tr...
Various lines of evidence indicate that men generally experience greater sexual arousal (SA) to erotic stimuli than women. Yet, little is known regarding the neurobiological processes underlying such a gender difference. To investigate this issue, functional magnetic resonance imaging was used to compare the neural correlates of SA in 20 male and 20 female subjects. Brain activity was measured ...
The present study examined men and women's sexual and affective responses to erotic film clips that were combined with different fantasy instructions. Men (n = 29) and women (n = 28) were presented with two types of erotic films (explicit vs. romantic) and two fantasy instructions (fantasizing about one's real-life partner vs. fantasizing about someone else). Genital response, subjective sexual...
Recent work has questioned whether the negativity bias is a distinct component of affective picture processing. The current study was designed to determine whether there are different neural correlates of processing positive and negative pictures using event-related brain potentials. The early posterior negativity and late positive potential were greatest in amplitude for erotic pictures. Parti...
OBJECTIVE AND METHODS Two experiments examined the impact of viewing unpleasant, pleasant, and neutral photographic slides on cold-pain perception in healthy men and women. In each experiment, participants viewed one of three slide shows (experiment 1 = fear, disgust, or neutral; experiment 2 = erotic, nurturant, or neutral) immediately before a cold-pressor task. Skin conductance and heart rat...
The effects of sympathetic nervous system (SNS) activation, induced via acute exercise, on sexual arousal in women was studied. In 2 experimental sessions, 36 women viewed a neutral film followed by an erotic film. In 1 session, the women were exposed to 20 min of intense exercise before viewing the films. Twelve women were sexually functional, 12 experienced significant impairments in sexual d...
Research indicates hysterectomy surgery may adversely affect the pelvic autonomic nerves and autonomic mechanisms are integral to the sexual arousal response in women. This study explored the possibility that women who undergo hysterectomy may experience an impaired vasocongestive response to erotic stimulation. Thirty-two women with a history of benign uterine fibroids who had ( n = 15) or had...
