(A) Cartoon illustrating set-up for single-unit recording during fear extinction, and example of isolated units. (B) Estimated microelectrode array placements. (C) Freezing behavior showing extinction in B6 mice and impaired extinction in S1 mice (n=6–7 mice per strain). Data are Means ± SEM. * P<.05 versus B6/same task-phase.
