McCulloch-Pitts neuron
     
         The basic building block of
        {artificial neural networks}.  It receives one or more inputs
        and produces one or more identical outputs, each of which is a
        simple non-linear function of the sum of the inputs to the
        neuron.  The non-linear function is typically a threshhold or
        step function which is usually smoothed (i.e. a {sigmoid}) to
        facilitate {learning}.
