BACKGROUND Tract-tracing studies in cats and rats demonstrated that the auricular branch of the vagus nerve (ABVN) projects to the nucleus tractus solitarii (NTS); it has remained unclear as to whether or not the ABVN projects to the NTS in humans. OBJECTIVE To ascertain whether non-invasive electrical stimulation of the cymba conchae, a region of the(More)
INTRODUCTION The projection of vagina, uterine cervix, and nipple to the sensory cortex in humans has not been reported. AIMS The aim of this study was to map the sensory cortical fields of the clitoris, vagina, cervix, and nipple, toward an elucidation of the neural systems underlying sexual response. METHODS Using functional magnetic resonance imaging(More)
BACKGROUND We analyzed an insertion/deletion (I/D) polymorphism of the angiotensin I-converting enzyme (ACE) gene in 1226 subjects from the Caerphilly Prospective Heart Disease Study. Amplification of genomic DNA using the polymerase chain reaction yielded the genotypes II, ID, and DD. Distribution of the polymorphism was analyzed among the whole group and(More)
The prevailing view in the literature is that hysterectomy improves the quality of life. This is based on claims that hysterectomy alleviates pain (dyspareunia and abnormal bleeding) and improves sexual response. Because hysterectomy requires cutting the sensory nerves that supply the cervix and uterus, it is surprising that the reports of deleterious(More)
BACKGROUND During the course of a previous study, our laboratory made a serendipitous finding that just thinking about genital stimulation resulted in brain activations that overlapped with, and differed from, those generated by physical genital stimulation. OBJECTIVE This study extends our previous findings by further characterizing how the brain(More)
BACKGROUND Although the literature on imaging of regional brain activity during sexual arousal in women and men is extensive and largely consistent, that on orgasm is relatively limited and variable, owing in part to the methodologic challenges posed by variability in latency to orgasm in participants and head movement. AIM To compare brain activity at(More)
BACKGROUND Stimulation of the vagus nerve via implanted electrodes is currently used to treat refractory epilepsy and depression. Recently, a non-invasive approach to vagal stimulation has demonstrated similar beneficial effects, but it remains unclear whether these effects are mediated via activation of afferent vagal fibers. OBJECTIVE The present study(More)
