- Information theory says: increase Hamming distances in C. - Neurophysiology says: this leads to weaker brain responses. - We attempted to optimize the tradeoff between these, but found that other factors (spatial layout) are also involved. - Physical stimulus type also interacts with these effects. Given the right stimulus, together with an error-correcting code, performance can be improved.
