This procedure when applied to mice has shown a reduced affinity for drugs, like addiction to cocaine. Moreover, such a procedure has also been seen to increase the appetite of the mice thus treated.
The latest procedure has showed that there may be a new treatment to deal with drug addiction through surgery in the subthalamic nucleus. Previous researches have shown that these procedures have been also effective for reducing the symptoms of Parkinson's disease as well.
