Values are means ± SE with number of neurons in parentheses. Control, data from neurons close to the normal border in nondenervated animals (from Hickmott and Merzenich 1998); normal, data from neurons close to a nonborder site in nondenervated animals (from Hickmott and Merzenich 1998); and acute, 7 day, 14 day, and 28 day; data from neurons close to the normal or reorganized border sites after the indicated duration of denervation.
