Construction of intracranial brain stimulation device with the ability to record brain signals
Researchers at Amirkabir University of Technology, by implementing a research project supported by the Development Headquarters of Cognitive Sciences and Technologies, started the design and construction of a cranial brain stimulation device with alternating electric current and simultaneous recording of brain electrical signals (EEG).
According to Isna, Dr. Mohammad Mehdi Ahmadi, a member of the academic staff of Amir Kabir University of Technology and the leader of this research project, said: Transcranial electrical stimulation of the brain (tCS) is one of the newest and least dangerous methods of intervention in the nervous system, which has been used significantly in recent years. It has been used to treat disorders such as depression, substance abuse, and Parkinson's.
He added: recording the electrical brain signal (EEG) simultaneously with the electrical stimulation of the brain creates many possibilities in the process of treating patients or further research in this field.
Ahmadi considered the purpose of this project to be to obtain a method for extracting the electrical signal of the brain during intracranial brain stimulation in order to adjust the parameters of the stimulation signal based on that and reminded: to record the brain signal during intracranial stimulation of the brain, it is necessary that the disturbing signal caused by Remove the stimulation from the recorded signal from the head to extract the electrical signal of the brain in a healthy way.
According to him, by using this system, it is possible to start research on closed-loop electrical stimulation systems of alternating current.
Pointing out that this closed-loop system can play a very effective role in controlling cognitive disorders and diseases, this researcher said: the constructed system can have a greater effect on the behavioral control of patients with autism, anxiety control, stammering, anger control, increase To have the power to make decisions and control the tremors caused by Parkinson's.
According to the headquarters of cognitive sciences, the leader of this research project also pointed out: by knowing the process of brain and cranial stimulation, stimulation protocols can be designed with high accuracy in order to make the cranial and cranial stimulation more effective, and also by increasing the security of the stimulation, more effective studies can be carried out. Performed on children.
A member of the academic staff of Amirkabir University of Technology continued: The implementation of this plan and the construction of the simultaneous recording and stimulation system will provide a platform for conducting research to increase people's cognitive abilities and treat people's mental illnesses, and this device is one of the necessary tools for research institutions and It will be an active treatment in the field of neurological and cognitive diseases.
The organizer of this project added: This project has been implemented as a combination of a master's project and a doctoral project with the support of the Development Headquarters of Cognitive Sciences and Technologies.
