| Abstract: | "The dual theory of sexuality is a work in progress that tries to put together all the significant physiological aspects described on this subject, the most recent published article discussing about the hormonal and pheromonal neuromodulation of somatic peripheral afferents. But sexuality and cognition shares common somatic peripheral afferents, so that a good understanding of sexual mechanisms supposes also a good knowledge of the essential psychological mechanisms/neuromodulators. Current psychological approaches could be limited to two general tendencies. Some authors consider that cerebral neuronal connexions generate a unitary network substrate that - increasing in its complexity - becomes compatible with our complex mental function. Others suggest that such a complex cerebral function correspond actually to a system based on subsystems, represented by distinct neuronal units (not necessarily complexes) that interact each other. Starting from basic somatic/sexual neurophysiological elements and general accepted psychological aspects, the discussion gave sense to the last point of view, namely that genesis of a new function is the result of cooperation between distinct structural and functional units. Contrary to the classical concepts, this paper sows the fact that mental perception corresponds actually (in term of touch/tangibility) to the internal representation of an external object while sensations realize an internal representation of the external characteristics of environmental object. As a conclusion, sexuality and cognition are two distinct autonomic/dual functions, interrelated at both cerebral and peripheral level. Peripheral interference implies intervention of some specific (mental and sexual) neuromodulators, making external information act as internal mental or internal sexual stimuli. Central cerebral interferences are also clinically and pharmacologically documented, specific neuromodulators being taken into account. Supplementary studies would be necessary to complete psychosexual dualism, presenting the association between image and perception for the genesis of visual perception or between image and sensation for the genesis of visual sensations, complex (mental or sexual) stimuli that suppose a synergic action between distinct neuromodulators. This central synergism supposes a peripheral synergism between left visual field and right nostril, aspects that will be discussed largely in a future article" |
