That image is from 1961 and an idealization. Here is an actual trajectory of fixational eye movements. The dots are 2 ms apart. If a midget ganglion cell, with single-cone receptive field, fires at 100 Hz, then every spike reports about a different cone. How can we ever read anything?

What a great figure! What we call “fixation” is really a complex pattern of fixational eye movements, several captured beautifully in this single shot. Love it! 👀 #EyeTracking
