Correction:In the article “Muscarinic Control of Long-Range GABAergic Inhibition within the Rhinal Cortices” by John Apergis-Schoute, Aline Pinto, and Denis Paré, which appeared on pages 4061–4071 of the April 11, 2007 issue, there was an error in the calibration bar of the currents of Figure 7. The correct values should be 40 pA for A1, 20 pA for A2 and A3, and 16 pA for B1 and B2.
