N |
• mice exhibit normal motor coordination, conditioned learning and spatial memory
|
• mice exhibit defects in consolidation of fear memory in a tone- and context-cued conditioning tests after 24 and 48 hours, respectively, compared with wild-type mice
• however, learning of the conditioned behavior is normal
|
• impaired after 24 hours
