Due to a printing error, some data were left off of Figure 2C in “Cholinergic Basal Forebrain Transplants Restore Diminished Metabolic Activity in the Somatosensory Cortex of Rats with Acetylcholine Depletion” by S.E. Jacobs, A. Fine, and S.L. Juliano, which appeared in the February 1994 issue, pp. 697–711. The correct figure appears above.
