In vivo measurement of cortical impedance spectrum in monkeys: implications for signal propagation.
TL;DR: It is proposed that the spatial summation of LFP and MUA is determined by the size of these signals' generators and the nature of neural events underlying them, rather than by biophysical properties of gray matter.

XXXIII. The theory of electrolytic polarization
TL;DR: In this paper, the authors derived the following equations: C p designates the polarization capacity, R p the polarization resistance, and ψ the phase angle defined by tan ψ = C p ωR p (ω: angular frequency of alternating current), and V(x)dq represents the value of the counter-electromotive force x seconds after a quantity dq of electricity has passed through the electrolytic cell.

TL;DR: The resistive properties of various tissues surrounding the heart were investigated in a number of living dogs and show that most tissues are comparable and that the resistivity decreases slowly as the frequency increases.
