Neurons in infralimbic and prelimbic cortex of chronically stressed rats that underwent paired fear conditioning are unresponsive to CS during conditioning and retrieval of extinction. Mean CS-related activity (expressed as percent change from baseline) of infralimbic (above) and prelimbic (below) units in the first 200ms (infralimbic) or 2 s (prelimbic) after CS onset for the initial or final trial for conditioning, extinction and extinction retrieval. Asterisk (*) indicates significant difference relative to unstressed; daggers (†) indicate significant differences relative to baseline.
