Webneuron; dut if at any time the neuron fires, and the axonal terminations are simultaneously excited, they become synapses of the ordinary kind, henceforth capable of exciting the neuron. The loss of an inhibitory synapse gives an entirely equivalent result. We shall then have THEOREM 7. WebThe artificial neuron ( McCulloc's mathematical neuron, Pitts [en] , the formal neuron [1] ) is a node of an artificial neural network that is a simplified model of a natural neuron. Mathematically, an artificial neuron is usually represented as some non-linear function of a single argument — a linear combination of all input signals.
