PURPOSE The purpose of this study was to examine the cerebral changes in high beta frequency oscillations (22-30 Hz) induced by sertraline and by audiovisual erotic stimuli in healthy adult males. MATERIALS AND METHODS Scalp electroencephalographies (EEGs) were conducted twice in 11 healthy, right-handed males, once before sertraline intake and again 4 hours thereafter. The EEGs included four...

Pathological gambling is an addictive disorder characterized by a persistent and compulsive desire to engage in gambling activities. This maladaptive behaviour has been suggested to result from a decreased sensitivity to experienced rewards, regardless of reward type. Alternatively, pathological gambling might reflect an imbalance in the sensitivity to monetary versus non-monetary incentives. T...

Importance Pornography consumption is highly prevalent, particularly among young adult males. For some individuals, problematic pornography use (PPU) is a reason for seeking treatment. Despite the pervasiveness of pornography, PPU appears under-investigated and basic questions remain unanswered. Objective To investigate the neural mechanisms underlying PPU in men. Design and participants Using ...

The current study investigated psi ability (precognition) based on Bem’s (2011) experiments. The study used a computer-based program that tested for the prediction of erotic stimuli via erotic and non-erotic images. Sensation seeking and cortisol were explored as moderators of psi ability. Participants provided saliva samples at the beginning and end of the study for a measure of cortisol. It w...

Previous studies have demonstrated variable influences of sexual hormonal states on female brain activation and the necessity to control for these in neuroimaging studies. However, systematic investigations of these influences, particularly those of hormonal contraceptives as compared to the physiological menstrual cycle are scarce. In the present study, we investigated the hormonal modulation ...

Considerable evidence has accumulated from studies in vivo and with tissue slices indicating that erotic acid (4-carboxyuracil), or a closely related compound, is a precursor of the pyrimidines in nucleic acid (l-6). In order to study the pathway of erotic acid metabolism at the enzymatic level, a source material capable of metabolizing large amounts of erotic acid was sought. Such a system was...

A definite connection of erotic acid with the biosynthesis of nucleic acid pyrimidines is provided by the finding that erotic acid (7) as well as thymine (8,9) can supplement or replace the folic acid required by certain microorganisms. As suggested by Chattaway (7)) it would appear that folic acid has a function in the biosynthesis of pyrimidines. Furthermore, this function is probably concern...

Although the combination of alcohol and sex is frequently observed in human social interaction, many questions concerning alcohol’s effects on the processing of sexual stimuli and brain functionality remain unanswered. Erotic films eliciting sexual arousal in humans and affect electroencephalographic (EEG) activity. This study examines the effects of alcohol on cortical EEG activity in young me...

Based on studies of heterosexual male fetishists, transvestites, and transsexuals, Blanchard (1991) proposed the existence of a hitherto unrecognized paraphilic dimension, erotic target location errors (ETLEs), involving the erroneous location of erotic targets in the environment. ETLEs can involve preferential attention to a peripheral or inessential part of an erotic target, manifesting as fe...

Exotic Becomes Erotic: Explaining the Enigma of Sexual Orientation Daryl J. Bem Cornell University In this address, I outline my “Exotic-Becomes-Erotic" theory of sexual orientation (Bem, 1996) , which provides the same basic account for both opposite-sex and same-sex erotic desire—and for both men and women. It proposes that biological variables do not code for sexual orientation per se but fo...
