THE HUMAN BODY AS AN EXOSKELETON OF THE ENCEPHALON: A DIFFERENT VIEW ABOUT THE ORGANIC SYSTEMS

ANDREW TOLEDO FISCHE R DA SILVA, JÉSSICA VENCATTO SENEM

Resumo


Introduction: In order to expand our knowledge about the consciousness´s processes and, equally,
deepen our conception of who we are, the body is demonstrated here as just an exoskeleton of the
encephalon. Material and Methods: Review of international bibliography and scientific articles, the
following platforms were used: www.scielo.org, www.ncbi.nlm.nih.gov/pubmed,
www.sciencedirect.com. The functionality of all the organic systems in the creation and maintence of the
organism were compared and simplified. In the same way, new studies and innovations over the cognitive
area were shown. Results: Unlike the more widespread views that the notion of ego is contained in all
the Central Nervous System, or even the whole body, the conscience is a consequence of the encephalon´s
activity, whereas the spinal cord is just a center of unprocessed actions, an intermediate and a pathway
for ascendant fibers. Analyzing the encephalon, injuries upon the brain stem reinforces its modulating
functions over the superior cortical networks. Equally, the cerebellum is presented, according to recent
works, as a modulation tool of the limbic and cognitive systems. Meanwhile, within the prosencephalon,
the Default Mode Network (DMN) that is, theoretically, the basal connections of the consciousness
showed rearrangement during psychedelic experiences and, united with the Claustrum´s switch of
cognition theory, provides new insights into the conscious universe as its pathways begin to appear.
Finally, during electrical stimulation of the left claustrum and anterior insula, an epileptic woman
manifested static behavior, aphasia and a complete lack of responsiveness, as well as amnesia. The effects
disappeared when the stimulation went off. Discussion and Conclusion: Whether analyzing the DMN and
Claustrum pathways or so many other perspectives and hypotheses about the processes of consciousness,
attention and cognition, one thing that is clear is that we do not possess the encephalon, we are it. Our
body is just and exoskeleton that we use for survival in the environment. Certainly, this vision will clarify
ideas and thoughts, expanding the human knowledge and catalyzing steps of scientific progress that
progresses our specie.
