Cross-modal enhancement (CME) occurs when the neural response to a
stimulus of one modality is augmented by another stimulus of a differ-
ent modality. Paired stimuli of the same modality never produce supra-
additive enhancement but may produce modality-speci c suppression
(MSS), in which the response to a stimulus of one modality is dimin-
ished by another stimulus of the same modality. Both CME and MSS
have been described for neurons in the deep layers of the superior collicu-
lus (DSC), but their neural mechanisms remain unknown. Previous in-
vestigators have suggested that CME involves a multiplicative ampli er,
