Erratum: In the article “A Monosynaptic GABAergic Input from the Inferior Colliculus to the Medial Geniculate Body in Rat,” by D. Peruzzi, E. Bartlett, P. H. Smith, and D. L. Oliver, which appeared on pages 3766–3777 of the May 15, 1997 issue, a printer’s error resulted in the unclear reproduction of Figure 4 (page 3771). The figure and legend are reprinted.
