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’).
