Correction: In the article “Profound Loss of Layer II Entorhinal Cortex Neurons Occurs in Very Mild Alzheimer’s Disease,” by T. Gómez-Isla et al., which appeared on pages 4491–4500 of the July 15, 1996 issue, the authors would like to correct the headings of the last columns in Tables 1 and 3. The headings should read, “Neuronal density (neurons/mm3 × 102).”
