    摘要： A method and system for detecting brain activity may be disclosed, the method including performing multi-channel synchronous collections of brain electrical signals and cerebral cortex blood oxygen signals simultaneously and ensuring synchronicity of the collected signals among channels by collecting the signals at multiple locations simultaneously. A system may include a functional near-infrared light source emission module, which may employ the frequency division multiplexing technique. A multi-functional joint collection helmet may access the light source signal emitted from the emission module, then may be processed by a near-infrared detection module. Further, the near-infrared detection module may detect optical signals of the scalp, while a brain electricity detection module detects electrical signals of the scalp. Finally, a central control unit may synchronize data collected from the detected signals and may control a variety of functional modules and upload the data to a host computer.

    摘要： A non-contact brain blood oxygen detecting system includes a mobile terminal device. The mobile terminal device includes a control module, a transmitting module, a receiving module and a display module. The control module is connected to the transmitting module, the receiving module and the display module, respectively. The transmitting module in the mobile terminal device is configured to emit dual-wavelength near-infrared light to a detected subject. The receiving module is configured to receive a light signal after propagation fed back by the detected subject, and to perform data conversion on the received light signal to obtain a digital signal containing blood oxygen information. The control module is configured to obtain the blood oxygen information of the detected subject according to the digital signal obtained by the receiving module. The display module is configured to display the blood oxygen information obtained by the control module.

    摘要： Disclosed are a method and system for brain activity detection. The method is: performing multi-channel synchronous collections of brain electrical signals and cerebral cortex blood oxygen signals simultaneously, and ensuring synchronicity of the collected signals among channels, and collecting said brain electrical signals and said cerebral cortex blood oxygen signals of all locations at the same time. The system comprises: a functional near-infrared light source emission module (2) which employs the frequency division multiplexing technique, wherein the light source is modulated by carrier of different frequencies, said signal is accessed from the multi-functional joint collection helmet (1) through a transmission optical fiber to irradiate the scalp, and after being scattered and absorbed by the brain, the attenuated light signal is processed by the functional near-infrared detection module (3); the functional near-infrared detection module (3) is used for detecting weak optical signals of the scalp; the brain electricity detection module (4) is used for detecting weak electrical signals of the scalp; the central control unit (5) is used for synchronizing and fusing data flows, sending control commands to each functional module, and uploading data to the host computer (6). The method and system can control the interference to be the minimum and have good time scale consistency.
