Here, we obtain a covariant formulation of Ohm’s law for an electromagnetic field tensor of any order derived from the emergent conductivity tensor in highly non-isotropic systems, employing the bidomain theory framework within brain tissue cells. With this, we offer a different perspective that we hope will lead to understanding the close relationship between brain dynamics and a seemingly ordinary yet profoundly crucial element: space.20 p.application/pdfengcc-by (c) Rivas, M. et al., 2024http://creativecommons.org/licenses/by/4.0/Camps electromagnèticsCircuits elèctricsEspais de LorentzCervellElectromagnetic fieldsElectric circuitsLorentz spacesBraininfo:eu-repo/semantics/article7556292025-03-31info:eu-repo/semantics/openAccess
