The present invention involves a method and a system for using electrical stimulation and/or chemical stimulation to treat depression. More particularly, the method comprises surgically implanting an electrical stimulation lead and/or catheter that is in communication with a predetermined site which is coupled to a signal generator and/or infusion pump that release either an electrical signal and/or a pharmaceutical resulting in stimulation of the predetermined site thereby treating the mood and/or anxiety disorder.

We claim: 1. A method of treating a mood disorder or anxiety disorder, comprising: surgically implanting an electrode in communication with a predetermined site selected from the group consisting of inferior thalamic peduncle and reticular thalamic nucleus; coupling the electrode to a pulse generating source; and treating the mood disorder or the anxiety disorder by generating an electrical signal with the pulse generating source wherein said signal electrically stimulates the predetermined site. 2. The method of claim 1 further comprising: surgically implanting a catheter having a proximal end coupled to a pump and a discharge portion for infusing a dosage of a pharmaceutical, wherein after implantation the discharge portion of the catheter is in communication with a predetermined site selected from the group consisting of inferior thalamic peduncle and reticular thalamic nucleus; and operating the pump to discharge the pharmaceutical through the discharge portion of the catheter into the predetermined site thereby chemically stimulating the predetermined site and treating the mood disorder and/or anxiety disorder. 3. The method of claim 2, wherein chemical stimulation of the predetermined site results in modulation of neuronal activity. 4. The method of claim 2, wherein the pharmaceutical is selected from the group consisting of an inhibitory neurotransmitter agonist, an excitatory neurotransmitter antagonist, an agent that increases the level of an inhibitory neurotransmitter, an agent that decrease the level of an excitatory neurotransmitter, and a local anesthetic agent. 5. The method of claim 1, wherein the mood disorder is selected from the group consisting of major depressive disorder, bipolar disorder, and dysthymic disorder. 6. The method of claim 5, wherein the mood disorder is major depressive disorder. 7. The method of claim 1, wherein the anxiety disorder is selected from the group consisting of panic disorder, posttraumatic stress disorder, obsessive-compulsive disorder and phobic disorder. 8. The method of claim 7, wherein the anxiety disorder is obsessive-compulsive disorder. 9. The method of claim 1, wherein electrical stimulation of the predetermined site results in modulation of neuronal activity. 10. The method of claim 1, wherein the predetermined site is the inferior thalamic peduncle. 11. The method of claim 1, wherein the predetermined site is the reticular thalamic nucleus.
