Even that doesn't seem to be accurate: “Using extensive co-staining with established markers, they were able to relate the twelve neuron classes to previously discovered molecular characteristics of functional enteric neuron types, thus classifying the ENCs into excitatory and inhibitory motor neurons, interneurons, and intrinsic primary afferent neurons.” With a sharper protocol and new information, the researchers were able to confirm and expand on the existing body of ENS neuron knowledge. And now they can work on finding out what each of the 12 ENS neuron types is responsible for, they say. Which sounds less like "now scientists know how it works in mice" and more like "now scientists know more about the different cell types it contains in mice."
