Parameters and abbreviations of IntelliCage behavior.
| Visits | Visits/h |
| NPvisits | Visits with Nosepoke without licks/h |
| Lvisits | Visits with Licks/h |
| SVisits | Visits without Licks and without Nosepokes/h |
| NPVdur | Median duration of Visits with NP w/out Lick (s) |
| Nosepokes | Mean number of Nosepokes during Visits with NP w/out Licks |
| NPduration | Median duration of such Nosepokes during a Visit (s) |
| Licks | Median number of Licks per Visit |
| Lduration | Median duration of Licking during a Visit (s) |
| Lcontact | Median bottle cap contact time during a Visit (s) |
| Nocturnal | Log(Visit frequency during dark phase/Visit frequency during light phase) |
| Repetitive | Repetitiveness, log(sum of observed returns to same corner/sum of expected such switches) |
| Regularity | Sqrt (sum of sq non-diag. transition matrix residuals/sum of non-diag. transition matrix observed values) |
| IVI | Intervisit intervals (s) i.e. time from end of visit to start of next corner visit |
| IVIrepdens | Intervisit intervals (s) for repeated use of the same corner |
| InstantFreq | Instantaneous frequency, reciprocal of the time from start of one visit to start of next visit |
| Unevenness | Describes the relative use of corners, ranges from 0 to 1 (0 = equal use of 4 corners, 1 = exclusive use of 1 corner) |
| Sidedness | Ratio of visits with first left versus first right NP of visits with NPs |
| Mesor | Midline estimating statistic of rhythm, a rhythm adjusted mean in cosinor analysis |
| Amplitude | Difference between Mesor and Peak activity |
| Acrophase | Time to maximum activity after Light Off (Light off set to 0) |
| Period | Duration of one cycle |
