Plasticity is an important feature of single units and one that is probably not available from LFPs. It ought to be easier to train one unit than an unruly classroom of poorly correlated units. The expectation is that perhaps any unit recorded from anywhere in the brain can be trained to control a specific output. If this plasticity expectation is to be fulfilled, however, there must be a priori stability of the unit. Without stability and longevity, repeated sessions of retraining would be required. Thus far, the NE is unique in achieving the goals of plasticity, stability, and longevity [4, 5, manuscript in preparation].
