N normal phenotype
behavior/neurological
• normal behavior in standard fear conditioning and 24-h contextual fear memory
• normal 24-h memory
• in observational fear task, where observer mouse that doesnt receive direct aversive stimuli is conditioned for context-dependent fear by observing a demonstrator mouse receiving repetitive foot shocks, the subject (observer) mouse displays fear when placed in the same environment without the demonstrator mouse
