neuron neuron from visual cortex of a rat motor neuron A simple feedforward neural networkIn a simple feedforward neural network, all signals flow in one direction, from input to output. Input neurons receive signals from the environment and in turn send signals to neurons in the “hidden” layer. Whether any particular neuron sends a signal, or “fires,” depends on the combined strength of signals received from the preceding layer. Output neurons communicate the final result by their firing pattern.
