Initiation à l'Oeuvre Médico-Scientifique de Sir Emanuel Swedenborg

Le IVème Ventricule, pièce maîtresse des Cerveaux (the Brains, comme dit Sir Emanuel Swedenborg) ne réagit et ne fontionne pas de la même manière - i.e. “selon la même logique appliquée aux ... “- que les Ventricules Latéraux ou le IIIè Ventricule. De par sa raison d'être et d'exister, qui s'explique et se comprend par son anatomie et sa physiologie, il tient une place centrale de haute importance, bien à part.

The Brain, volume II, chapitre XXVI, The Fourth Ventricle, Analysis, p.375 & ss., extraits:

“705: The fourth ventricle, which, by some of our modern anatomists, is made of no account, or deemed of only slight importance, but which, by the old anatomists, was esteemed most highly, ...; [...]; [...]“

“705. [...]; [...]; for thence, as from a principal, mediating cause, comes the power, as wellas the exertive force of the motions of the whole encephalon, that is, of the cerrebellum, medulla oblongata, spinal marrow, and, by connection therewith, also of the cerebrum and its chymical organs.“ [...]

“706. The cerebellum derives thence the power of its motion, that is, its power of expansion and constriction; [...]: for the outermost parts must conspire with the middle in the production of the same effect.[...].“

“710. Yet not the cerebellum, medulla oblongata, and spinal marrow alone are affected, but the cerebrum also carries on its motions, and especially the chymical organs of its laboratory accomplish their operations in harmony with this ventricle, for without the service and auxiliary function of this ventricle the cerebrum and its members would soon be seized as it where with a swoon, and would cease to act; because there is a continual nexus of all things, and indeed a certaon chain and series from first to last things through the middle. If therefore, either the cerebellum or the medulla oblongata, or the spinal marrow, or if, going still further, the lungd or the heart were struck with an inability of action, a similar effect would at once be communicated to the cerebrum. The cerebellum is so connected with its cerebrum as to expect from its government and an alternate motion akin to its own. In the medulla oblongata, the fibre of the cerebrum reigns equally with that of the cerebellum; likewise in the spinal marrow; and the fibre of the cerebrum which comes from its front part, descends into the meddula of the neck and of the back through the pons Varolii, in the closest proximity to the bottom, and the walls of this ventricle, while that which comes from its own crown flows down the same way, through the isthmus, close to the edges of the ventricle. If, therefore, the alternate and reciprocal action of the ventricle should cease, that of the fibre, and consequently, that of the cerebrum itself would cease; for in order that the cortex may possess mobility itself, it must have motion and action in the middle parts and in the extreme or end; because in its extreme or end resides the active force of its power, which must act the part of one and the same cause, in order that the cerebrum may have the power of motion.“

“711. [...]. It follows thence that without the reciprocal action of the fourth ventricle, and without its action upon the valve of Vieussens, and through the valve upon the aqueduct, the third ventricle would remain emptied and unsupplied with its desired lymph; and consequently also the lateral ventricles, the pineal gland, the infundibulum and the pituitary gland, and thus the organs and members of the chymical laboratory. “

“712. [...]. That most refined lymph which is propelled through the reticular plexuses of the medulla of both brains, and through the interstices and pores of the nerves of the body, is not the animal spirit itself, but is impregnated with spirit; [...]"

“713. [...]. It seems, however, that the above cavity ought not to be called with Aurantius a cistern of spirits, but the cistern of a spirituous lymph; for no fibre, conveying the genuine spirit, empties into it.“

Lorsque le Cortex/Matière Grise effectue sa Diastole, le 4ème Ventricule effectue également sa Diastole - s'expand et se remplit - contrairement aux Ventricules Latéraux et au 3ème Ventricule, qui eux, effectuent leur Systole et se vident - afin de permettre la distribution/diffusion de l'Elixir Premier et de l'Information Première puis du LCR selon les besoins de “nourriture“ et d'informations, du SNC et par voie de conséquence de tout l'organisme.

The Brain, volume II, chapitre XXVI, The Fourth Ventricle, Analysis, p.384:

“715. [...]. It was shown above that the acqueduct is filled and swollen when the lateral ventricles and the third ventricle are constricted, which happens when the cerebrum and cerebelllum, and also the fourth ventricle are expanded. Thus this latter ventricle alternates with the acqueduct in its motions, as has been maintained above.

IMPORTANT: William Garner Sutherland, le dit père de “l'approche crânienne“, nous explique quant à lui que tous les ventricules effectuent leur systole et leur diastole en même temps et de manière synchronisée.

Cf. par exemple dans les extraits ci-dessous reproduits.

Explication reprise et acceptée telle quelle par tous ses élèves et successeurs puis de manière générale, par les ostéopathes depuis toujours.

Contributions of Thought, The Collected Writings of William Garner Sutherland, D.O., 1998 second edition, pp. 217-218 & 219, extracts:

pp. 217-218: “[...]. ...the fourth ventricle... . During inhalation periods of respiration, the ventricle dilates, in common with all the other ventricles, while during exhalation periods, the fourth and all the other ventricles return to contraction. [...]

p. 219: [...]. The third and lateral ventricles, as well as the cerebral aqueduct and the spinal canal, also possess motile physiological activities in connection with the fourth chamber during alternating periods of respiration: dilating during inhalation and contracting during exhalation, [...]. [...]

W. G. Sutherland ne serait-il pourtant pas dans l'erreur ?

Ce qui est sûr, c'est que la présentation anatomico-fonctionnelle des ventricules que nous présente et nous offre Sir Emanuel Swedenborg est la seule que nous ayons qui soit la plus compréhensible, parce que la complète, la plus détaillée, la plus précise, la plus cohérente et la plus objective, de bout en bout.
