    摘要： A nervous tissue imaging system and a method therefor. The system includes: a housing containing an excitation light source, optically coupled with a source optical train, the excitation light source emits excitation light in a first wavelength range, which can be in a near ultraviolet light range, to illuminate a tissue region of interest including healthy nervous tissue and healthy non-nervous tissue. The excitation light in the first wavelength range causes the healthy nervous tissue, in response to being illuminated with the excitation light, to endogenously autoflouresce and emit first autofluorescence light at a first luminance in a second wavelength range. The healthy non-nervous tissue, in response to being illuminated with the excitation light, either avoids emitting any autofluorescence light in the second wavelength range; or endogenously autoflouresces and emits second autofluorescence light in the second wavelength range at a second luminance that is lower than the first luminance.

    摘要： A biological signal measurement system includes: a providing unit configured to provide a first visual stimulus including a first object visually changing at a predetermined frequency, and a second visual stimulus including a second object; a detection unit configured to detect a biological signal of the subject; a frequency analysis unit configured to perform a frequency analysis on the detected biological signal corresponding to the first visual stimulus, and derive a signal intensity of each frequency component; a determination unit configured to determine a time interval in which the subject has viewed the first visual stimulus, based on a signal intensity of a frequency component corresponding to the frequency; an extraction unit configured to extract the biological signal corresponding to the determined time interval, and corresponding to the second visual stimulus; and an output unit configured to output the extracted biological signal.
