COLLOQUIUM PAPER Correction for “Understanding dopamine and reinforcement learning: The dopamine reward prediction error hypothesis,” by Paul W. Glimcher, which appeared in issue S3, September 13, 2011, of Proc Natl Acad Sci USA (108:15647–15654; first published March 9, 2011; 10.1073/pnas.1014269108).
The authors note that, due to a printer’s error, the legends for Figs. 1–5 appeared incorrectly. The figures and the corrected legends appear below. These errors do not affect the conclusions of the article.

Fig. 3.
“When a reward is cued and delivered, dopamine neurons respond only to the cue. When an expected reward is omitted after a cue the neuron responds with a suppression of activity as indicated by the oval” (30).
