Electric model for virtualizing electrocorticogram from scalp electroencephalogram

The invention discloses an electrical model for virtualizing electrocorticogram from scalp electroencephalogram, which comprises an electroencephalogram signal subtractor, an electroencephalogram signal preamplifier, an electroencephalogram signal integrator and an electroencephalogram signal adder which are connected in sequence, and the electroencephalogram signal subtractor subtracts a reference potential from a scalp electroencephalogram signal to obtain an input signal of the electroencephalogram signal preamplifier; the electroencephalogram signal preamplifier is used for amplifying electroencephalogram signals, the electroencephalogram signal integrator is used for carrying out phase adjustment on the electroencephalogram signals, the electroencephalogram signal adder is used for summing the two paths of electroencephalogram signals, and therefore the electrical model structure design for converting scalp electroencephalogram into electrocorticogram is achieved. 本发明公开了一种从头皮脑电虚拟皮层脑电的电模型，包括依次连接的脑电信号减法器、脑
