Comparisons of selectivity in LMAN and X
| Selectivity category | LMAN | X |
|---|---|---|
| BOS > tutor | 31/56 (55%) | 19/49 (39%) |
| BOS > adult conspecific* | 36/47 (77%) | 24/47 (51%) |
| BOS > juvenile conspecific | 17/30 (57%) | 17/34 (50%) |
| BOS > heterospecific* | 43/51 (84%) | 31/47 (66%) |
| BOS > reverse BOS | 34/47 (72%) | 30/41 (73%) |
| BOS > reverse order BOS | 15/37 (41%) | 15/32 (47%) |
| Tutor > BOS* | 6/56 (11%) | 14/49 (29%) |
| Tutor > adult conspecific | 20/41 (49%) | 26/48 (54%) |
| Tutor > heterospecific | 24/42 (57%) | 33/51 (65%) |
| Tutor > reverse tutor | 16/37 (43%) | 25/45 (56%) |
| Tutor > reverse order tutor* | 5/21 (24%) | 19/37 (51%) |
The ratio of selective cells to the total tested in each category is shown for LMAN and X, followed by the percentages. Cells were considered selective if the d′ value for the two stimuli compared was ≥0.5.
*
Comparisons for which the frequency of occurrence of selective cells was significantly different between LMAN and X neurons (χ2 tests; χ2 = 6.64 for BOS > adult conspecific; p < 0.0101; χ2 = 4.457 for BOS > heterospecific; p < 0.0349; χ2 = 5.404 for tutor > BOS; p < 0.0202; χ2 = 4.189 for tutor > reverse order tutor;p < 0.0408).
