Emotion is defined as any mental experience with high intensity and high hedonic content. [1] The existence and nature of emotions in non-human animals are believed to be correlated with those of humans and to have evolved from the same mechanisms.
It is difficult to develop an animal model that perfectly reproduces the symptoms of depression in patients. It is generic that 3 standards may be used to evaluate the reliability of an animal version of depression: the phenomenological or morphological appearances (face validity), a comparable etiology (assemble validity), and healing similarities (predictive validity).
Animal psychopathology is the study of mental or behavioral disorders in non-human animals. Historically, there has been an anthropocentric tendency to emphasize the study of animal psychopathologies as models for human mental illnesses. [ 1 ]

The LHb also projects to aversion reactive mPFC neurons, which may provide an indirect mechanism for producing depressive behaviors. [ 134 ]

Zebrafish have also been used to test the medicinal benefits of certain psychoactive drugs, particularly how they can be used to treat mental health problems. [38] A study looking into the antidepressant properties of ketamine using zebrafish as subjects found that when exposed to small amounts of ketamine (2 mg/L), zebrafish displayed more ...
