Optoretinography of human retina (IMAGE)
Caption
Researchers developed a simple and fast way to perform optoretinography that measures the speed, or velocity, at which the retinal neurons move relative to each other. The grayscale image is a cross-section of a living human retina near the fovea, acquired using a custom optical coherence tomography camera. The pseudocolor overlay shows the phase velocity of the tissue. Analysis of the photoreceptor phase velocity reveals that these cells contract and expand within twenty milliseconds of the onset of a visible stimulus flash.
