The use of appropriate quantitative tools assigning numerical values to the observed variable is necessary to define good descriptors of the electroencephalogram, allowing comparisons between different recordings. In this line, we propose a numerical method for the spectral and temporal reconstruction of a brain signal. The convergence of the procedure is analyzed, providing results of the concerned approximation error. In a second part of the text, we use the methodology described to the quantification of the bioelectric variations produced in the brain waves for the execution of a test of attention related to military simulation. info:eu-repo/grantAgreement/ES/UZ/CUD2013-16 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 1.017 2016 MATHEMATICS, APPLIED 108 / 255 = 0.424 2016 Q2 T2 0.697 2016 Engineering (miscellaneous) 2016 Q1 Mathematics (miscellaneous) 2016 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Navascues, Maria Antonia (orcid)0000-0002-8885-7492 Ruiz, C.
