Activation of the basolateral amygdala induces long-term enhancement of specific memory representations in the cerebral cortex

- The basolateral amygdala strengthens remotely stored memories.
- Auditory cortical tuning plasticity serves as memory representations.
- Waking rats receive one session of tone paired with BLA stimulation.
- Stimulation rapidly induced specific tuning shifts, maintained for at least 3 weeks.
- Thus, BLA may strengthen memory by increasing number of its representative cells.
