“…6,12 Recent studies provide compelling evidence for the involvement of the vagus nerve in the sensory component of orgasm. Komisaruk et al 13,14 hypothesised that the nucleus tractus solitarii in the medulla oblangata to which the vagus nerves project, is activated during orgasm. Support for this theory is derived from animal studies 13 and functional magnetic resonance imaging on women with complete SCI at or above T10 (n ¼ 4), 14 which demonstrated activation of the inferior region of the nucleus tractus solitarii on vaginal-cervical selfstimulation.…”

Results: The literature focuses on the effect of neurological change on women's ability to achieve sexual arousal and orgasm. Urinary and bowel incontinence, spasticity, vaginal lubrication and autonomic dysreflexia are the physical consequences of SCI that appear to have most impact on sexual activity. More recent studies have acknowledged that psychosocial factors such as age and partnership status may also affect the successful sexual rehabilitation. Discussions with women with SCI in Denmark and Sweden on their reactions to information and counselling offered during rehabilitation revealed an overwhelming need for the exchange of information and experience with other women with SCI, and a desire for opportunities for counselling after initial rehabilitation. Conclusion: Successful sexual rehabilitation of women with SCI demands a holistic approach that considers individual neurological, physical and psychosocial circumstances. Peer-counselling could make a significant contribution to the sexual rehabilitation of women with SCI.

“…Hence, it is problematic to equate simple intensity and satisfaction. Self-report studies consistently show predictable differences between orgasms on the basis of stimulation site, which is consistent with the objective physiological differences between vaginal, cervical and clitoral stimulation (Komisaruk, Beyers-Flores, & Whipple, 2006;Komisaruk & Whipple, 1995;Komisaruk et al, 2004Komisaruk et al, , 2011. It is surprising that Prause argues against self-report studies, given that her proposals are almost exclusively based on self-reports.…”

“…Vaginal stimulation also produces a much greater analgesic (but not anesthetic) response than clitoral stimulation, which further increases when the vaginal stimulation elicits orgasm -this effect is not explained by distraction (Komisaruk & Whipple, 1995;Komisaruk et al, 2004;Whipple & Komisaruk, 1985, 1998.…”

“…Studies reveal that vagina and clitoris activate distinct afferent pathways (Komisaruk, Beyers-Flores, & Whipple, 2006;Komisaruk et al, 2004) and that stimulation of clitoris, vagina and cervix activate different regions of the brain's sensory cortex (Komisaruk et al, 2011). Such cortical differences are likely due to distinct afferents: sensory information from the clitoris to the brain is transmitted mainly by the pudendal nerve, whereas vaginal and cervical sensation is additionally conducted by the pelvic, hypogastric and vagus nerves (Komisaruk et al, 2004(Komisaruk et al, , 2006. The vagus nerve is the main constituent of the parasympathetic branch of the autonomic nervous system and bypasses the spinal cord.…”

This paper reviews evidence from behavioral and brain sciences to assess whether, and for what reasons, this assumption may be warranted. It is claimed that the decision makers' difficulties can be explained once the motivational aspects of utility ("wanting") are disentangled from the experiential ones ("liking") and the features of the different psychological processes involved are recognized.
