The last decade is marked by an increased interest in studying the possibility of direct communication between the brain and external devices, including the brain of another person. The most accessible type of brain-computer interfaces uses multi-channel electroencephalographic signals that non-invasively record brain activity. Despite active research in this direction, it has not been possible to achieve natural control of external devices solely on the basis of non-invasively recorded brain signals.
At the same time, animal experiments have shown that using deep electrodes that record the activity of a large number of individual neurons, it is possible to create brain-controlled devices that reproduce natural motor actions, such as capturing and moving objects and walking on two legs. Invasive IMC can decode and schedule movements over time.
Application of such technology to the creation of interfaces on people is limited by high risks of using needle electrodes, arising complications, as well as fouling of needle electrodes with a connective tissue and loss of electrical contact. A reasonable compromise is the use of subdural or epidural nets of electrodes, allowing with a low risk to the health of the user to significantly increase the capacity of the direct communication channel with the brain, and also through electrostimulation to realize somatosensory feedback.
The main goal of the Laboratory is the development of the information technology of bidirectional communications using the corticographic interface in combination with modern methods for processing multidimensional data and somatosensory feedback through electrostimulation or sensory replacement.
The project is carried out jointly with the clinical medical centre of the Clinical Medical Centre of MGMSU and the Polenov Russian Research Institute of Neurosurgery, who are the clinical bases of this interdisciplinary project.
The development of the interface is based on knowledge of the functional significance of areas of the cerebral cortex. Such information can be obtained using the methods of neurocardication which is another field of research of our laboratory.
October, 29-30 the Cortical Codes: Control & Perception (CCCP) conference will be held in HSE, Moscow.
Centre for Bioelectric Interfaces designes not only brain-computer interfaces, but myographic interfaces as well (controlled by the electrical activity of muscles). Analysis of the electromyographic (EMG) signals of the anterior forearm muscles, recorded from the area of 1.5 square cantimeteres, allows to reconstruct fingers movements (see the video).
The annual Volga Neuroscience Meeting will be held on the ship "Mikhail Frunze" from July 22 to July 27.

We proceed to create a multi-channel atomic magnetoencephalograph sensor for high-precision non-invasive functional brain mapping
HSE in cooperation with "Laserlab" became the winner of the "Development-NTI" competition, held by the Innovation Support Fund.
Center for bioelectric interfaces launches the joint project with the ExoAtlet company to develop a brain-computer interface for the rehabilitation of patients with locomotor disorders of the lower limbs. More effective complex therapy will be possible as a result of combining the medical exoskeleton (ExoAtlet, https://www.exoatlet.com/ru) with the recording of the patient's electroencephalogram (EEG). Using an exoskeleton a patient will perform one locomotion cycle, if she can concentrate on the imaginary leg movement, which can be detected as the desynchronization of the patient's motor rhythm on EEG.
Alexei Ossadtchi is the head of the project with Rosatom "Development of a multi-channel atomic magnetoencephalograph for non-invasive high-resolution brain mapping (AM-MEG)"
The development of a magnetic encephalograph of a new generation on the basis of a compact highly sensitive magnetometric sensor will allow the non-invasive recording of electrical activity of the human brain and heart with previously inaccessible spatial and temporal accuracy. The new technology for measuring superweak magnetic fields, which does not require the use of cryogenic equipment, will significantly reduce the cost of the device, make it accessible to a wide range of clinical and research institutions, and provide superiority in the tasks of diagnosing neurological and cardiac disorders, as well as in cognitive studies.
