title: Erratum.
abstract: In the report by L. D. Fetcher and Z. Annau [197, 680 (1977)], the values for whole brain dopamine levels in 1-day-old rats were given as 5.47 +/- 1.62 and 3.01 +/- 0.81, microg/g (wet weight) in air and CO subjects injected with L-dopa. The correct values are 5.47 +/- 0.38 and 3.01 +/- 0.20 microg/g. The difference between the groups is significant at P < .01 as reported.
