Document Summary

Outline: sine waves, frequency filters and receptive fields, basic visual pathway and properties, cellular features of visual cortex. Gutenberg"s printing press: gutenberg invented printing press in 1440, biggest invention in last 100 years, ended dark ages, followed by rapid technological revolution, similar technology invented earlier in asia, but did not have profound influence. The sine wave: most oscillations are sinusoidal, vibrating guitar string, piston in our car engine, pendulum swinging left and right, dropped mass on spring, tidal height, radio signals, sound. Where the: motion , retina: m cells, lgn: magno layers, cortex: dorsal, color/form, retina: p cells, lgn: parvo layers, cortex: ventral. Sine wave gratings: amplitude (contrast, frequency (cycles/degree, phase, orientation (rotation) At most center is about 1 degree: each of these cells tuned to a particular size. Amplitude is also known as the contrast of a sine wave.
