How are animals currently used in research on brains and behavior, and what safeguards are currently in place for animal welfare in scientific research? Why do researchers use animals to study human brains and behaviors? What (if any) alternatives are available to using animal models?

Solution

In order to understand the human psyche, animals are subjected to experiments related to vision, pain perception, hunger, thirst, fear, stress, aggression, fetal development, learning process etc. For this purpose animal\'s behavior and environmental conditions are manipulated, most commonly by genetic engineering. This leads to development of a programmed live scenario, wherein, the living system can be guided accordingly.

Reaserchers use animals to study human behaviours because of ethical ease as well as controlled conditions that are easily available in case when animals are employed to shed light on human psychic conditions.
