    MathWorks Inc two-dimensional gaussian noise made with the randn command
    ( a ) The mean total distance moved by the eye of one observer that was consistent with OKN in the stimulus direction, for 16 drifting noise trials across five spatial frequencies, and eight velocities. Note substantially more OKN consistent motion at lower SFs. ( b ) As ( a ) but showing the total proportion of eye movements consistent with OKN in the stimulus direction (C θ ). ( c ) The optimum velocity (derived from <t>log-Gaussian</t> fits to 6 observers similar to ( b )) as a function of SF. ( d ) As for ( c ) but showing the amplitude of the log-Gaussian fit (a measure of signal-to-noise ratio) which does not show a strong dependence on SF, within observer.
    Two Dimensional Gaussian Noise Made With The Randn Command, supplied by MathWorks Inc, used in various techniques. Bioz Stars score: 90/100, based on 1 PubMed citations. ZERO BIAS - scores, article reviews, protocol conditions and more
