This concept came to epitomize the general neurobiological principle that complex information can be encoded on the level of individual neurons.
Soon, researchers were finding command neurons in multiple invertebrate and vertebrate species, including crickets, cockroaches, lobsters, and teleost fish.
[5] The article initiated a torrent of tumultuous debate about which neurons, if any, could fit the new, more rigorous definition proposed by Kupfermann and Weiss.
[6] Many believe that the command neuron concept needs to be reworked in light of the subtleties uncovered by Kupfermann and Weiss' careful methodology.
[7] Command decisions are increasingly seen as being governed by networks of interacting and redundant cells, not simply by single neurons.
