Display behaviours, human

A better resemblance to the human depressive state in comparison with monoamine-depleted animals is claimed for animal separation models. Dog puppies separated from their mother display behavioural syndromes similar to human depression in which vocalization is most pronounced. Among a large number of drugs, imipramine was found most effective in reducing vocalization, without causing sedation [28]. 

Experimental animals display a characteristic set of behaviours after they stop eating and before they start eating again referred to as the satiety cascade (Blundell 1992). Humans are much more variable. In some cultures it is customary to sleep for an hour or so ( siesta ), particularly after a large lunch. In other cultures the mid-day meal is a much briefer affair and work resumes shortly after the meal ends. However, even in these societies it is not uncommon to feel somewhat lethargic after eating. 

There could be a whole host of system and human factor behaviours which could give rise to this impact. For example, the prescriber could select the wrong medication, a system defect could display a different medication to that which the prescriber chose, the drug dictionary or reference data could have become corrupt, etc. These scenarios all relate directly to the system or its operation and therefore they are good candidates for causes.
