These criteria are often tested by: # Recording the activity of the command neuron during stimulus presentation that triggers a given behavior. # Showing that the behavior cannot be evoked after removal of the command neuron (necessary). # Stimulation of the command neuron can elicit the behavior (sufficient). In some cases, a group of interneurons together form a command system while the individual members, known as command-like neurons, may not satisfy both the necessity and sufficiency criteria.
