SUMMARY
Responses of neurons in early visual cortex change
little with training and appear insufficient to account
for perceptual learning. Behavioral performance,
however, relies on population activity, and the accu-
racy of a population code is constrained by corre-
lated noise among neurons. We tested whether
training changes interneuronal correlations in the
dorsal medial superior temporal area, which is
involved in multisensory heading perception. Pairs
