Table 1.

Testing arrangements and outcomes of the various biconditional tasks and place discrimination (Go/No-go)

Experiment Description Group Room Direction Impaired?
Exp 1 Biconditional discrimination (nose-poke) ATNx1 A n/a No
Pre-training Pre-training (digging in cup) ATNx1 B n/a n/a
ATNx2 C n/a n/a
Exp 2A Digging media discrimination ATNx1 B n/a No
Exp 2B and 2C Biconditional (open area, digging) ATNx1 B Bidirectional Partial
Exp 2D and 2F Place biconditional ATNx1 B Bidirectional Yes
Exp 2E Context biconditional ATNx1 B n/a No
Exp 3A Go/No-go ATNx2 B Bidirectional Yes
Exp 3B Go/No-go ATNx2 D Unidirectional Partial
Exp 4 Place biconditional ATNx2 D Unidirectional Yes

Only the lesion groups are displayed in the Table, but the respective control group was also tested in the same room (i.e., ATNx1 with Sham1, ATNx2 with Sham2). Whether the animals were tested approaching the digging cup from a single direction (unidirectional) or two directions (bidirectional) is noted. Performance is indicated as being unimpaired (‘No’), markedly impaired (‘Yes’) or only mildly impaired (‘Partial’).
