Background: Electric and magnetic field-generating systems must be insulated in order to maintain their balance. It is certain that the brain, which has a very intense electric and magnetic field, is insulated by the dura mater and cerebrospinal fluid (CSF) that surround it. In this article, the electrophysical properties of these structures will be postulated in accordance with the laws of mathematics and physics.
Material and Methods: In human samples, on the other hand, the morphological features of EEG waves were examined with parameters such as the number of scalp hairs and scalp thickness, conductivity, skull thickness, ratios between cranial and brain volumes, and the thickness of the subarachnoid space where CSF circulates, and ventricular volumes. Since this study is postulative, the data were not detailed by statistical evaluation.
Results: With the geometric shapes of EEG waves; scalp thickness and number of hairs, skull thickness, depth of subarachnoid space, ventricular volumes, thickness of dura mater. EEG artifacts were excessive in pediatric cases with closed fontanelles or in adults with bone defects. There were statistically varying safety limits between 0.05 Conclusion: The morphological structure of the skull and brain is fundamental in determining the nature of the EEG waves. The artifact of EEG waves in infants with open fontanelles and individuals with cranial bone defects may result from the rupture of the cerebrospheric armor formed by the dura.
