Digital implementation of Hodgkin–Huxley neuron model for neurological diseases studies


Neurological disorders affect millions of people which influence their cognitive and/or motor capabilities. The realization of a prosthesis must consider the biological activity of the cells and the connection between machine and biological cells. Biomimetic neural network is one solution in front of neurological diseases. The neuron replacement should be processed by reproducing the timing and the shape of the spike. Several mathematical equations which model neural activities exist. The most biologically plausible one is the Hodgkin–Huxley (HH) model. The connection between electrical devices and living cells require a tunable real-time system. The field programmable gate array (FPGA) is a nice component including flexibility, speed and stability. Here, we propose an implementation of HH neurons in FPGA serving as a presage for a modulating network opening a large scale of possibilities such as damage cells replacement and the study of the effect of the cells disease on the neural network.
