Fig 3. Saccharin intake for sham and dls lesioned animals in E-exp and N-exp groups.

E-exp groups was exposed to saccharin for five days before conditioning day. N-exp were only exposed to saccharin the conditioning day. A (left). The graphic shows the five sessions of preexposure phase for the 10.00 am session and (right) saccharin intake during conditioning phase. B. Effects of dls lesion on mean saccharin intake in extended exposure groups (E-exp) to the future CS during the test phase. Error bars represent SEMs. Asterisks indicate p<0.01. N-exp: non-exposed groups, E-exp: extended exposure groups.
