Incomplete and off-target infusions confirm a critical role of cerebellar cortex in consolidation.

Expanded view of CR acquisition in Phase 1 (mean CR frequencies for successive 10-trial blocks of Phase 1 in all experimental groups, followed by mean session frequencies for each session of Phase 2 and 3). Rate of acquisition is related to depth of cortical inactivation with muscimol: Cortex+Nucleus (n = 4) subjects fail to acquire robust CRs during Phase 1, whilst Incomplete (n = 6) subjects do acquire CRs, but not as rapidly as Nucleus Only (n = 7) and Off-Target (n = 10) subjects, which acquire CRs at a similar rate to Controls (n = 4).
