Later, cable theory with its mathematical derivatives allowed ever more sophisticated neuron models to be explored by workers such as Jack, Rall, Redman, Rinzel, Idan Segev, Tuckwell, Bell, and Iannella. More recently, cable theory has been applied to model electrical activity in bundled neurons in the white matter of the brain. [1]
Wilfrid Rall (August 29, 1922 – April 1, 2018) was a neuroscientist who spent most of his career at the National Institutes of Health.He is considered one of the founders of computational neuroscience, and was a pioneer in establishing the integrative functions of neuronal dendrites.
The magnetic field inside a coaxial cable can be divided into three regions, each of which will therefore contribute to the electrical inductance seen by a length of cable. [ 11 ] The inductance L cen {\displaystyle L_{\text{cen}}\,} is associated with the magnetic field in the region with radius r < a {\displaystyle r<a\,} , the region inside ...
The linear cable model makes several simplifications to give closed analytic results, namely that the dendritic arbor must branch in diminishing pairs in a fixed pattern and that dendrites are linear. A compartmental model [65] allows for any desired tree topology with arbitrary branches and lengths, as well as arbitrary nonlinearities. It is ...
Exposure to ELF waves can induce an electric current. Because the human body is conductive, electric currents and resulting voltages differences typically accumulate on the skin but do not reach interior tissues. [22] People can start to perceive high-voltage charges as tingling when hair or clothing in contact with the skin stands up or ...
The Hodgkin–Huxley model, or conductance-based model, is a mathematical model that describes how action potentials in neurons are initiated and propagated. It is a set of nonlinear differential equations that approximates the electrical engineering characteristics of excitable cells such as neurons and muscle cells .

They were developed by Oliver Heaviside who created the transmission line model, and are based on Maxwell's equations. Schematic representation of the elementary component of a transmission line. The transmission line model is an example of the distributed-element model. It represents the transmission line as an infinite series of two-port ...
