Rhesus Monkey Summary

Dr. Jeffrey M. Schwartz is a leading research psychiatrist at the University of California Los Angeles who is intrigued by the similarities in rhesus monkeys and individuals suffering from Obsessive Compulsive Disorder. By weaving together some of the most historic research studies in neuroscience through the frame of Obsessive Compulsive Disorder, Schwartz argues in The Mind & The Brain that adult brain is a plastic thing. Using groundbreaking research in the study of neuroplasticity, Schwartz works to inform individuals with brain disorders and injuries that it is possible to rewire the physical makeup of the brain.
Case Studies E.T. Rolls, an Oxford University behavioral physiologist, conducted a key experiment on rhesus monkeys. He and …show more content…

If acting without the cue of the light, the monkeys received nothing. Using electrodes implanted in their brains, Rolls and his team were able to monitor the activated sections of the brain. The orbital frontal cortex, the part of the brain responsible for the directing and fine-tuning of complex behavior and planning, became stimulated when acting on the blue light signal. The orbital frontal cortex analyzes situations and determines the proper response. In a heathy brain, the orbital frontal cortex sorts stimuli, interpreting between normal and abnormal events. The system coordinates and regulates a proper response, calming the individual. After this finding, Rolls exchanged signals so that a green light would produce juice and a blue light would produce salt water, which the rhesus monkeys dislike. When the monkey participants, who had been conditioned for juice at …show more content…

For decades, the man lived constantly with dry, cracked hands, unable to stop his habits in spite of the pain. The compulsions to remove worrisome germs controlled his schedule so much so that his wife was threatening to divorce him when he came to the UCLA research study in 1987. He spent one year with Schwartz and his team, working with no avail. After a year with the program, his exhaustion and pain finally cause him to fight against the compulsions. He determined that he would rather die than live with the triggers. At that point, he stopped washing his hand more than necessary. Both James and the rhesus monkeys, eventually adapted their planning systems and, as a result, saw physical changes in the brain make up and response to triggers. The monkeys learned to expect black current juice at the sight of a green light. James was able to stabilize his fear and recognize when he did not need to wash his
