Construction of the transcranial electrical stimulation device for treatment of cognitive disorders and diseases at the department of biomedical engineering, Amirkabir University of technology

Dr. Farzad Tohikhah, the executor director of constructing the transcranial electrical stimulation system with the advantage of focused stimulation, claimed: a sample of a transcranial electrical stimulation system is designed and constructed which is able to produce multiple types of DC and AC currents at the department of biomedical engineering, Amirkabir University of technology. This project which has been supported by cognitive sciences and technology council, was designed and constructed based on the international standards and are competitive and comparable with similar foreign ones. “In order to have a more focused current on brain cortex, the multichannel version is under construction. So that increased number of channels and smaller electrodes, provide more flexibility for researchers and therapists to design various current assignment protocol. This approach taking advantage of the use of stimulating electrodes, for applying focused current to the brain cortex”, he added.

Approaches to developing an effective method of electrical stimulation using this device have presented for diseases such as Parkinson and reducing nerve pains”, the member of science board of Amirkabir University of technology said.

Considering the unique feature of the transcranial electrical stimulation devices to storing the variation in resistance value during stimulation, models were developed for differentiating between the responsive and non-responsive patterns of individuals to transcranial electrical stimuli. The results of experiments will lead to the development of knowledge in this area, he also added.
