Neurons and Neural Networks: Computational Models
نویسندگان
چکیده
Neural networks produce electrical activity that is generated by the biophysical properties of the constituent neurons and synapses. Mathematical equations can be used to describe the electrical activity of neurons and neural networks and the underlying biophysical properties. These equations give rise to computational models of neurons and networks that can be analysed using mathematical techniques or numerically simulated with computers.
