Mechanistic description

The transgenerational stability of migration routes suggests extended critical periods for spatial learning. Pharmacologically reopening critical periods could allow recovery of lost spatial memories.

Mechanism / pathway

  1. PSD-95, CREB, perineuronal net components
  2. spatial memory
