Mentally Created Neuroplasticity

by Tim Brunson, PhD
In prior articles my focus has been on how neuroplasticity follows sensory-deprivation or changes in how the senses are used. Findings derived from his work with Obsessive Compulsive Disorder (OCD) patients led Jeffry Schwartz, MD, (2002) a University of California – Los Angeles Medical School neuropsychiatrist to the realization that the signals capable of creating neural reorganization can also come from the mind. His analysis of the causes and treatment for OCD focuses on a small handful of neural substrates. These include the right orbitofrontal cortex (R-OFC), the striatum [i.e. the region of dopamine receptors to include the anterior cingulate cortex (ACC)], the limbic system's amygdala, and the caudate nucleus. Together he calls them the "OCD circuit."
