A RESEARCH MODEL SYSTEM AND A METHOD FOR USING ELECTRICAL STIMULATION AND/ CHEMICAL STIMULATION TO INDUCE DEPRESSIVE ILLNESS IN RESEARCH ANIMALS

摘要

The present invention concerns a research model system for causing a depressive illness in an animal subject other than a human being, said system comprising a probe having a stimulation portion in communication with the subcallosal area; and a device to stimulate the probe thereby activating the subcallosal area and causing the depressive illness. By a research model system and method according to the invention, there is provided a research system allowing for causing an increase of activity in the predetermined areas so that test of depressive illness treatment methods can be performed in this research model.
