WebAn experiment published in 1959 launched Wiesel and Hubel's collaboration of more than 20 years. Using a then-new electrophysiological technique of recording the activity of single brain cells in cats, they found in this and later studies that some cortical cells respond to contours of specific orientation. WebIn mathematics, physics, and engineering, spatial frequency is a characteristic of any structure that is periodic across position in space. The spatial frequency is a measure of how often sinusoidal components (as determined by the Fourier transform) of the structure repeat per unit of distance. The SI unit of spatial frequency is cycles per ... health canada dietary guidelines
