Iranian Scientists Make Cranial Electrotherapy Stimulation Device for Brain Studies
“Electrical and cranial brain stimulation is one of the newest and least dangerous methods of intervention in the nervous system, which in recent years has been significantly used in the treatment of disorders like depression, drug use and Parkinson's disease,” said Mohammad Mehdi Ahmadi, a faculty member of the Amirkabir University of Technology and the head of the research team.
“Recording brain electrical signal (EEG) simultaneously with brain electrical stimulation creates many possibilities in the process of treating patients or further research in this field,” he added.
Noting that the purpose of the research project is to obtain a method for extracting the electrical signal of the brain during intracranial brain stimulation to adjust the parameters of the stimulation signal, Ahmadi said, “To record the brain signal during intracranial brain stimulation, it is necessary to remove the disturbing signal caused by the stimulation from the signal recorded from the head to extract the electrical signal of the brain in a healthy way. By using this system, research can start on the closed loop systems of electrical stimulation of alternating current.”
In a relevant development last November, Iranian specialists at a knowledge-based company had also succeeded in making a surgical navigation system that uses a special tracking system to display the exact position of the surgical tool in the patient's CT scan or MRI images to the surgeon at any moment to perform surgery more precisely and calmly.
“Our company uses advanced technologies for processing and displaying medical images combined with real-time positioning of surgical instruments to perform the surgical processes of brain tumors, sinus and skull base surgeries, brain sampling and spine surgery with high precision and reliability,” said Alireza Ahmadian, the managing director of the knowledge-based company.
Noting that in surgery with navigation, in addition to identifying the exact position of the lesion within the structures of the central nervous system (brain or spinal cord), a safer route for neurosurgery is created, he said, “Surgical navigation is similar to mobile or car GPS, and by using this tracking system, it can show the position of the surgical tool in the patient's CT scan or MRI images to the surgeon at any moment so that the surgeon can have accurate information about the position of his/her tool.”
“The smart surgery system produced in our company has advantages like increasing surgical accuracy, reducing the probability of tumor recurrence, and increasing the probability of removing the tumor completely, and it does not require repeated surgeries, reducing damage to other sensitive organs of the patient,” Ahmadian said.
