NEUROSCIENCE. For the article “Neural correlates of perceptual learning: A functional MRI study of visual texture discrimination,” by Sophie Schwartz, Pierre Maquet, and Chris Frith, which appeared in number 26, December 24, 2002, of Proc. Natl. Acad. Sci. USA (99, 17137–17142; First Published November 21, 2002; 10.1073/pnas.242414599), on page 17138, the last sentence beginning at the bottom of the right column:
“Axons from the temporal retina cross in the optic chiasm and project to ocular dominance columns in the contralateral hemisphere, whereas axons from the nasal retina do not cross and project to ocular dominance columns in the ipsilateral hemisphere (21).”
should read:
“Axons from the nasal retina cross in the optic chiasm and project to ocular dominance columns in the hemisphere contralateral to the eye, whereas axons from the temporal retina do not cross and project to ocular dominance columns in the hemisphere ipsilateral to the eye (21).”
The conclusions of the article remain unchanged.
