چکیده
In this paper, we develop a novel approach for bidirectional brain-machine interface (BMI). First, we propose a neural network model for the sensory cortex (S۱) connected to the neural network model of the motor cortex (M۱) considering the topographic mapping between S۱ and M۱. We use the ۴-box model in S۱ and ۴-box in M۱ so that each box contains ۵۰۰ neurons. Individual boxes are composed of two neural populations: inhibitory interneurons and pyramidal neurons. Next, we develop a new BMI algorithm based on neural firing. The main concept of this BMI algorithm is to close the loop between two components: the sensory interface and the motor interface. The sensory interface encodes some of the state parameters of the external device into an electrical stimulus delivered to the S۱ model. The motor interface takes neural recordings from the M۱ model and decodes them into a force applied to the object. We present the simulation results for the online BMI which means that there is a real-time information exchange between the S۱-M۱ network model and the external device.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
