After the neuron electrical activity simulator works stably, it outputs the neuron response including the electromagnetic memory effect, that is, the membrane potential x. The invention considers the electromagnetic memory effect of neuron membrane potential discharge and ensures the regularity of neuron electrical activity.

Description

technical field [0001] The invention belongs to the field of electronic technology, and in particular relates to a neuron electrical activity simulator under electromagnetic radiation. Background technique [0002] In 1952, British biologists Hodgkin and Huxley proposed the ionic theory about the electrical activity of biological neurons, and based on this, they established the H-H neuron model that can simulate the neuronal membrane potential activity. Under the appropriate parameters and external stimuli, the model can simulate such phenomena as spike discharge, burst discharge and chaotic discharge observed in the axonal action potential experiment of calamari. In 1981, Cathy Morris and Harold Lecar simplified the H-H model to obtain the Morris–Lecar neuron model including ion channel effects. At present, among many simplified neuron models, the Hindmarsh-Rose neuron model is often used to study neurons Pattern shift of electrical activity. On the other hand, considerin...

Problems solved by technology

[0003] But no matter what kind of research, when neurons or neural tissues are in a complex electromagnetic environment, such as figure 1 As shown, the behavior of neuron electrical activity must be affected by multiple scales, such as the conductance and activation of ion channels, and the excitability may be affected, which will further affect the law of neuron electrical activity
