of single neurons in command decisions. Despite Kupfermann and Weiss' scathing critique of the loose fashion with which the command neuron concept was being used in the late 1970s and the resultant abandonment of the concept by some, the command neuron concept is still extant in the most current neurobiological literature. Some accept the revisionist "command-like" neuron concept—believing that no neurons exist which can satisfy the strictures outlined in "The Command Neuron Concept". Others cling to the use of the original command neuron concept as useful, rejecting the Kupfermann and Weiss strictures, and using less stringent definitions of the term (most seem to believe that there is a spectrum of pre-motor command organization: from parallel distributed networks on the one end, to command neurons on the other).
