The short-term replicability of the mismatch negativity (MMN) between two recording sessions spaced 2 h apart was evaluated at individual and group levels in a sample of 11 healthy adults. Subjects were presented with a random sequence of 1000 Hz standard (92%) and 1100 Hz deviant (8%) tones while they were reading a book. The N1 and P2 exogenous components to standard tones showed a fairly good individual and group replicability. There were no significant differences in the MMN amplitude and latency between the two sessions in the group of subjects as a whole. The individual replicability of the MMN was not as good as for the N1 to standards, reaching significance in only some of the electrodes. This result was, however, similar to that obtained for the N1 after deviant tones. The results indicate that the MMN has good replicability at the group level, and further that at the individual level, MMN replicability is similar to that of the N1 to deviants. This suggests that the number of summations should be increased in order to improve the clinical usefulness of the MMN.
