|---|---|---|---|
| a | Paired response onset latencies (fast vs slow sniffs), n = 13 cells | Paired t test | –25 to –7 ms |
| b | Paired response onset latencies (fast vs slow sniffs), n = 5 pMCs | Paired t test | –39 to –22 ms |
| c | Paired response onset latencies (fast vs slow sniffs), n = 8 pTCs | Paired t test | –16 to 1 ms |
| d | Normal distributions of equal variance | Unpaired Student’s t test, 2-tailed | 11 < 23 < 34 ms |
| e | Paired response onset latencies (high vs low concentration, n = 4) | Paired t test | 2.3 to 33 ms |
| f | SD in inhalation duration for passive (n = 23) and concentration go/no go mice (n = 7), calculated for each block (1 block = 10 trials) | Two-way ANOVA on SD in inhalation duration [factors: block #, behavior (passive vs concentration go/no go)] | Multiple comparison test: –10 < 5 < –2 ms |
| g | Go rate for fast and slow sniff trials for each concentration (5), for n = 3 mice trained on low Go contingency | Three-way ANOVA on go rates [factors: mouse, concentration, sniffing (fast vs slow)] | Multiple comparison test: –20 < –10 < –1% |
| h | Go rate for fast and slow sniff trials for each concentration (5), for n = 4 mice trained on high Go contingency | Three-way ANOVA on go rates (factors: mouse, concentration, sniffing (fast vs slow)) | Multiple comparison test: –22 < –15 < –7% |
| i | Difference in go rate between fast and slow sniff trials for each concentration (5), for mice trained on two different contingencies: “low go (n = 3 mice)” and “high go (n = 2 mice)” | Two-way ANOVA on differences in go rate (factors: contingency, concentration) | Multiple comparison test: –16 < –4 < 7% |
| j | Normal distributions of equal variance | Paired t-test | –15 to 4% |
| k | Go rate for probe trials and control trials for each concentration (5), for n = 3 mice trained on low Go contingency | Three-way ANOVA on go rates [factors: mouse, concentration, trial type (probe vs control)] | Multiple comparison test: –16 < –7 < 3% |
| l | Go rate for probe trials and control trials for each concentration (5), for n = 4 mice trained on high Go contingency | Three-way ANOVA on go rates [factors: mouse, concentration, trial type (probe vs control)] | multiple comparison test: –19 < –8 < 3% |
| m | Difference in go rate between probe and control trials for each concentration (5), for mice trained on two different contingencies: “low go (n = 3 mice)” and “high Go (n = 2 mice)” | Two-way ANOVA on differences in go rate (factors: contingency, concentration) | Multiple comparison test: 13 < 1 < 16 % |
| n | Paired reaction time data (fast vs slow sniffing, n = 5 mice) | Paired t test | 0.0 to 70 ms |
| o | Paired reaction time data (puff vs control, n = 5 mice) | Paired t test | –61 to 50 ms |
| p | Contingency table (significant vs non-significant R 2, actual data vs shuffle controls) | Fisher’s exact test | 3.4 to 18.3 |
| q | Contingency table (significant vs non-significant R 2, actual data vs shuffle controls) | Fisher’s exact test | 3.5 to 23.3 |
