The Functional Neurometry of Nelson Alves Pereira Júnior: An Advanced Method of Mapping and Biofeedback Training of the Autonomic Nervous System Functions

Abstract

Introduction: Functional Neurometry makes Biofeedback tools already demonstrated in the literature, such as: galvanic skin response, cardiac coherence and variability, thermoregulatory and respiratory interact with each other. Objective: The aim of this study was to report the historical and methodological aspects of the Functional Neurometry protocols. Method: A review was made in the MEDLINE / PubMed electronic indexing database and in the Web of Science. Results: This method intends to synchronize the frequencies of various organs linked to the autonomic nervous system (ANS) to control anxiety. Assessment and training are organized into categories. The categories of the assessment protocol are: 1st) Anxiety Control; 2nd) Physiological Response; 3rd) Baroreflex Index; 4th) hemodynamics; and 5th) Brain Neurometry and the training protocol categories are: I) Sound Anxiety Control; II) Visual Anxiety Control; III) Emotional Variability; IV) Respiratory Amplitude and Frequency; V) Progressive Muscle Relaxation; VI) Functional Physiological Response; VII) Respiratory Functional Capacity; VIII) Heart Rate Variability and IV) Cardiac Coherence. Conclusion: Functional neurometry mainly allows the balance of the ANS, making it a protective filter of the central nervous system.

Hemodynamics, baroreflex index and blood biomarkers of a patient who died after being affected by COVID-19: case report

“…Thus, the FN was performed in 3 positions: dorsal decubitus, standing up and orthostatic, called DSO analysis by the author, organizer and creator of the method, Nelson Alves Pereira Júnior. 27 The sympathetic autonomic nervous system represents the vasoconstrictions measured at the frequencies of 0.01-0.04 Hz and from 0.04 to 0.20 Hz and the parasympathetic represents the vasodilatations measured at the frequencies of 0.20-0.50 Hz. 27 The five categories of this evaluation protocol of DSO analysis were named by the author as: anxiety control; physiological response; baroreflex index; hemodynamics (blood flow velocity); and brain neurometry.…”

Detailed descriptions of each category, which captures biological signals by sensors calibrated in Series and/or Fourier Transform algorithms, have been published in the Journal of Psychology and Psychotherapy Research (DOI: https://doi.org/10.12974/2313-1047.2020.07.1).…”

In Functional Neurometry, anxiety control is measured through the galvanic skin response.…”

“…30 In this context, as sweat on the skin allows greater electrical conduction, 31 it can be estimated that with a greater amount of sweat there seems to be less energy stored in the liver (glycogen) for a person's adrenal to enable the fight and/or flight process or for that adrenal to control anxiety through the hormones aldosterone, cortisol, adrenaline and dehydroepiandrosterone. 27 The anxiety control category is calculated using a scale with agreed values from 0 to 100%, in which the level of energy provided by the functional reserve already absorbed by the enterocytes and already stored in the liver can be measured indirectly, 32 awaiting the need to pass into the bloodstream by glycogenolysis 33 to make the fight and/or flight process feasible. 34 The minimum expected in this category is 75%.…”

“…smoking, 16 insulin resistance, 17 increased homocysteine, 18 among others, which enable vascular responses with cytokines, 19 chemokines, 20 adhesion molecules, 21 heat shock proteins 22 and antibodies, 23 leading to inflammation, 24 oxidative stress 25 and autoimmune dysfunction. 26 Atherosclerosis and vascular disease are postprandial phenomena, that is, they arise after eating allergenic and inflammatory foods, 27 associated with hyperglycemia and hypertriglyceridemia, with endothelial dysfunction being the earliest stage of vascular disease, which can be detected through the baroreflex index, hemodynamics 27 and biomarkers already studied in the literature, linked to cardiovascular diseases. 28 In this sense, this study aimed to report the values of the baroreflex and hemodynamic index related to biomarkers that signal obstruction of the blood microcirculation found in the 57-year-old male patient, who died after being affected by COVID-19.…”
