I'd be interested in hearing more about this. What criteria were used

Amen! If there only were six types we'd probably know everything by
Except for specail restricted purposes (retina physiolgy, cerebellum
physiology, etc.) the notion of a few types of neurons or standard
circuitry has no credibility among neuroscientists.
