 als exhibit innate appetitive and aversive responses to specific odor stim
 uli\, while also learning to approach or avoid odors through experience. A
 lthough the innate behavioral responses must be established genetically\, 
 we found that these responses can be altered by odor experience during ear
 ly postnatal experience\, through a process known as olfactory imprinting.
  We found that exposure to odors during the developmental critical period 
 of the olfactory system converts innately aversive odors into homing signa
 ls for mice under threat. Mechanistically\, early odor exposure alters the
  projection patterns of olfactory sensory neurons\, thereby changing odor 
 identity. We found that this developmental plasticity required a populatio
 n of cells during perinatal neurogenesis. Moreover\, we identify a master 
 regulator that orchestrates axon plasticity and gene expression during the
  critical period. Its absence disrupts the closure of the critical period 
 and abolishes odor imprinting.\n
