Title:
BRAIN INTERNAL STIMULATION AND DETECTION SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/046002
Kind Code:
A1
Abstract:
A brain internal stimulation and detection system and method, which belong to the technical field of electroencephalogram data processing, and solve the problems in the prior art of poor accuracy and poor real-time performance of a collected electroencephalogram signal. The system comprises a processor (1) and an electrode (3), wherein the electrode (3) is used for collecting an electroencephalogram signal of a target brain position, and transmitting the electroencephalogram signal to the processor (1); the processor (1) is used for acquiring a β-band signal from the electroencephalogram signal on the basis of the electroencephalogram signal, sequentially performing Hilbert transformation and sliding window integration on the β-band signal, so as to obtain a brain observation feature value, and determining, on the basis of the brain observation feature value, whether the brain state is normal; and if it is determined that the brain state is abnormal, the processor (1) is further used for controlling the electrode (3) to generate a corresponding stimulation signal to act on the target brain position. An electroencephalogram signal can be accurately collected, and discrimination is performed on the basis of a frequency-domain feature of the signal, such that the accuracy is high, the data processing speed is high, and the real-time performance is excellent.
