| 摘要 |
Method and apparatus for detecting nerve activity of an animal Some embodiments include outputting a light pulse having a wavelength onto a volume of animal tissue such that the light pulse interacts with active nerves of the tissue, measuring a light signal resulting from the interaction of the light pulse with the tissue, transmitting an electrical signal based on the measured light signal, signal-processing the electrical signal, and outputting a response signal, which can optionally be used to control a prosthetic device, stimulate another nerve, or display/ diagnose a condition Some embodiments output a plurality of light wavelengths and/or pulses, which are optionally high-frequency intensity modulated Some embodiments analyze DC, AC, and phase components of signals to spatially resolve locations of neural activity Some embodiments output light pulse(s) and detect the resultant light from outside a human skull to detect neural activity of human brain tissue inside
