Is the hippocampus necessary for consolidation?

• Deactivation of hippocampus after learning to block memory consolidation

  • • Implantation cryotrode in hippocampus
  • • CS-US presentation (shock -context)

• • Cooling hippocampus (continuous)

• • Test of CS retention after 2-3 weeks in `cooled' and `uncooled' animals.
