Effects of 4-CIN infusions into the hippocampus and striatum on double object location (dOL) and double object replacement (dOR). A: Recognition index scores show that 4-CIN infusions into hippocampus impaired recognition for dOL but not dOR recognition (left panel). Conversely, infusions into the striatum impaired dOR but not dOL recognition (right panel). All saline (sal)-treated rats, except those with striatal infusions tested on dOL, showed recognition of changes in objects from study session (S)3. B: Time exploring both objects during S1, S2, S3, and test sessions following hippocampal infusions or striatal infusions (C). Object exploration curves reveal a decline in exploration across S1 through S3. Rats that recognize a change during test show an increase in exploration compared to S3. * p < .0125 sal versus 4-CIN; ^ p < .05 versus 0, within subjects.
