|
| Drug administration |
Bipolar disorder-associated hyperactivity [65] |
Locomotor activity evaluation in psychostimulants administration |
Psychostimulants can cause hyperactivity |
| Drug-induced anxiety [66] |
Pentylenetetrazol, sodium lactate, m-chlorophenylpiperazine, cholecystokinin administration |
Several drugs can be used to generate anxiogenic responses |
| Withdrawal-induced depression [67] |
Addictive substances administration |
Depression can also occur as a specific symptom of drug withdrawal |
|
| Physiological stress |
Manic-like behaviour [68] |
Locomotor activity, aggressivity, changes in sexual activity during sleep deprivation |
Sleep deprivation (>72 h) causes manic-like behaviour |
| Hyperthermia induced anxiety [69] |
Anxiety assessment in high environmental temperatures |
Anxiety-like behaviour can be induced by high environment temperatures |
| Helplessness-induced depression [70] |
Iterative physiological stress |
Animals learn that no escape conditions are provided; therefore they fail to exhibit escape behaviour also in the absence of the stimuli |
|
| Psychological stress |
Resident-intruder paradigm-based aggressivity [71] |
Locomotor activity, aggressivity, changes in sexual activity during social stress |
Aggressive behaviour can be a collateral effect in resident-intruder paradigm |
| Ultrasonic vocalizations-induced anxiety [72, 73] |
Ultrasonic distress in mouse pups separated from their mothers |
The decrease in the number of calls, anxiolytic effect |
| Hyponeophagia-induced anxiety [74] |
Feeding behaviour during/after anxiogenic stimulus of novelty |
Novelty in food or environment suppressed feeding |
| Maternal deprivation [75, 76] |
Maternal deprivation during early postnatal phases |
Although controverted, maternal deprivation during infancy can cause depressive disorders occurrence in early adulthood |
| Resident-intruder paradigm and social defeat-based depression [77] |
Depression assessment in males during consecutive cohabituation |
Males can be exposed to psychological stress as a result of consecutive habitation in cages |
| Social hierarchization-based depression [78] |
Depressive behaviour in tree shrews social hierarchy and subordination |
Natural depressive behaviour can occur in different species as a result to social hierarchy |
