Before revision: " Available data demonstrate that discrete regions of the cerebellum and associated brainstem areas contain neurons that alter their activity during conditioning – these regions are critical for the acquisition and performance of this simple learning task.
After revision: " ...The American neuroscientist David A. McCormick performed experiments that demonstrated discrete regions of the cerebellum and associated brainstem areas contain neurons that alter their activity during conditioning – these regions are critical for the acquisition and performance of this simple learning task.
