 e responses to specific odor stimuli\, while also learning to approach or 
 avoid odors through experience. Although the innate behavioral responses m
 ust be established genetically\, we found that these responses can be alte
 red by odor experience during early postnatal experience\, through a proce
 ss known as olfactory imprinting. We found that exposure to odors during t
 he developmental critical period of the olfactory system converts innately
  aversive odors into homing signals for mice under threat. Mechanistically
 \, early odor exposure alters the projection patterns of olfactory sensory
  neurons\, thereby changing odor identity. We found that this developmenta
 l plasticity required a population of cells during perinatal neurogenesis.
  Moreover\, we identify a master regulator that orchestrates axon plastici
 ty and gene expression during the critical period. Its absence disrupts th
 e closure of the critical period and abolishes odor imprinting.\n
