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 ]
[6] [7] [8] Depression is a heterogeneous disorder and its many symptoms are hard to produce in laboratory animals. When studying depression used in animals originally, symptoms equivalent to odd social behavior and emotion were used to determine if the animal had depression. [9] The question therefore remains whether we can know if the animal ...
Atrophy of the hippocampus has been observed during depression, consistent with animal models of stress and neurogenesis. [116] [117] Stress can cause depression and depression-like symptoms through monoaminergic changes in several key brain regions as well as suppression in hippocampal neurogenesis. [118]
Those who reject that animals have the capacity to experience emotion do so mainly by referring to inconsistencies in studies that have endorsed the belief emotions exist. Having no linguistic means to communicate emotion beyond behavioral response interpretation, the difficulty of providing an account of emotion in animals relies heavily on ...
Animals avoid inbreeding only rarely. [2] Inbreeding results in homozygosity which can increase the chances of offspring being affected by recessive traits. [3] In extreme cases, this usually leads to at least temporarily decreased biological fitness of a population [4] [5] (called inbreeding depression), which is its ability to survive and ...
WASHINGTON (AP) — U.S. officials on Thursday approved drugmaker BioMarin's gene therapy for the most common form of hemophilia, a $2.9 million infused treatment that can significantly reduce ...
Immunocompromisation and/or coinfection with FeLV, FIV and other Mycoplasma species can exacerbate symptoms or cause symptoms to arise in previously asymptomatic individuals. Symptoms include anemia, lethargy, fever, and anorexia. [5] In suspected cases polymerase chain reaction (PCR) tests have become common and commercially available. There ...
However, in the 1960s, it was shown that animals produced a blood-carried factor X that acted upon the brain to cause sickness behavior. [ 11 ] [ 12 ] In 1987, Benjamin L. Hart brought together a variety of research findings that argued for them being survival adaptations that if prevented would disadvantage an animal's ability to fight infection.
