Neuron physiology is actually described using the well known models created by Hodgkin-Huxley (HH) and their derivatives which came later, the Fitzhugh-Nagumo (FN) equations. These attempts to understand the internal functioning of the neuron are unfortunately far from the strict Nature's observation. These equations, particularly, are unable to explain an unidirectional propagation of action p...

press training and may be reluctant to engage the media. However, many universities employ press officers with journalism background and keen to work with scientists in communicating their papers to the media. Scientists need to be more proactive in working with traditional and new media, recruiting the help of their press offices, and communicating their findings to the general public through ...

We describe the origin and significance of electrical and mechanical observations on nerves. To this end, we compare two models for neural activity, which are the established Hodgkin–Huxley model and the more recent soliton theory, respectively. While the Hodgkin–Huxley model focuses particularly on the electrical aspects of the neural membranes, the soliton model is based on hydrodynamic and t...

In this research, the aim is to develop a repetitive firing stopper mechanism using electrical fields exerted on the fiber. The Hodgkin – Huxley nerve fiber model is used for modeling the membrane potential behavior. The repetitive firing of the nerve fiber can be stopped using approaches based on the control theory where the nonlinear Hodgkin – Huxley model is used to achieve this goal. The ef...

A blink in history's eye has brought us an understanding of electricity, and with it a revolution in human life. From the frog leg twitch experiments of Galvani and the batteries of Volta, we have progressed to telegraphs, motors, telephones, computers, and the Internet. In the same period, the ubiquitous role of electricity in animal and plant life has become clear. A great milestone in this j...

A hybrid system is proposed to model the electrical potential emitted by a neuron as a response to an externally applied DC current. Experimentally, Hodgkin and Huxley built a four-dimensional and nonlinear dynamical system to simulate this activity. Our idea is to use a new continuous and piecewise affine approximation as a hybrid model of the Hodgkin-Huxley dynamic. Our new model reproduces t...

This paper describes the bio-inspired visual signal processing by neuromorphic system, mimicking the primitive behaviour of visual cortex. The neuromorphic components are investigated for implementation of the visual signal selectivity of cortex, based on the CMOS conductance-based synaptic connections and neurons of Hodgkin-Huxley formalism. The proposed neuromorphic system exhibits the biolog...

In this work, an efficient numerical method for the complex solutions of nonlinear partial differential equations based on the direct algebraic approach is proposed, and tested in the case of generalized Burgers–Huxley equation ∂u ∂t + αu ∂u ∂x − ∂ u ∂x2 = βu(1− u)(u − γ) Whenα = 0, δ = 1, is reduced to the Huxley equation. The proposed scheme can be used in a wide class of nonlinear reaction–d...
