Corrections: In the article “Presynaptically Located CB1 Cannabinoid Receptors Regulate GABA Release from Axon Terminals of Specific Hippocampal Interneurons” by István Katona, Beáta Sperlágh, Attila Sík, Attila Käfalvi, E. Sylvester Vizi, Ken Mackie, and Tamás F. Freund, which appears on pages 4544–4558 of the June 1, 1999 issue, Attila Käfalvi's last name was inadvertently misspelled and should have been listed as Köfalvi.
