![]() Amniote Gastrulation) forming an inner layer known as mesoderm made up of cells which have migrated from the epiblast to the interior of the embryo, via the primitive streak. Gastrulation “initiates at the primitive streak, a groove formed by internalizing cells along the posterior axial midline” ( Houston, 2017, 6.6.3. ![]() In brief, during a process known as gastrulation, the morphological structure of the human embryo is changed from a flat two-dimensional disc to a three-dimensional tri-laminar disc. However, according to van der Wal (2003/2014), it is not a derm but an inner layer which “creates space and connects at the same time” (p. In the theory of the three germ layers, the inner layer is called mesoderm. 174-175) (emphasis added).Īn organic basis for his models eluded Freud all his life, but considering our anatomical development gives rise to insights that might provide a solution to his dilemma. Our psychical topography has for the present nothing to do with anatomy, it has reference not to do with anatomical locations but to regions in the mental apparatus, wherever they may be situated in the body.” (pp. 326) 1įreud (1915a) felt there was a hiatus between his psychical system and its basis which could not be filled by psychologists “ There is a hiatus here which at present cannot be filled, nor is it one of the tasks of psychology to fill it. But apart from this conviction, I do not know how to go on, neither theoretically nor therapeutically and therefore must behave as if only the psychological were under consideration. I am not at all in disagreement with you, not at all inclined to leave psychology hanging in the air without an organic base. In a letter Freud wrote to Fleiss on the 22 nd September 1898, he says: The paper follows the order of my explorations. The research centred around this suggestion but as it unfolded, the original hypothesis expanded to include a possible link between systems, layers, structures, and levels of consciousness and Freud’s model. I refer to this hypothesis as “the meso hypothesis”. My initial investigation involved the consideration of a possible link between the middle of the three-germ layer that forms during our anatomical development, known as mesoderm, and the organic basis of Freud’s topographic model of the mind and his structural model of the psyche. Rather, it grew out of my research as an intuitive insight as I began to gather the data presented in this paper where I started from an interdisciplinary perspective based mainly on embryogenesis. The thesis that there is possible correlational and/or developmental relationship between systems, layers, structures, levels of consciousness and Freud’s model of the mind, was not contemplated at the beginning of my investigation. Resistance to accessing this inner “unconscious” layer is probably related to an early tendency in controlling the expression of emotional and instinctual behaviour. This perspective also throws light on Freud’s agents of the psyche or soul, where the ego is the chief protagonist and whose actions and decisions are affected by unconscious processes. As the activities, contents, and history related to the meso layer predate temporal reasoning associated with the prefrontal cortex, our contact with this deeper layer is either direct through feeling and sensation, which predate verbal thought, or indirect using free association and dreams. In this paper, the possible links between these aspects are explored. ![]() It rests on three premises or postulates: 1) mesoderm might provide the key to the organic basis of Freud’s topographical and structural models, both of which involve primary and secondary systems 2) mesoderm is not a limiting skin, but a layer that simultaneously creates space and connects: 3) as it gives rise to the major structural components and organs of the inner body including the notochord (made of three-dimensional meso tissue) which underlies and promotes the development of the CNS made of neuroectoderm, mesoderm also involves primary and secondary aspects. The main body of the paper leads to the insight that there might be a correlational and/or developmental relationship between systems, layers, structures, levels of consciousness and Freud’s model of the mind.
