The idea that the visual system carries out information processing similar to Fourier analysis is supported by the observation that
A)horseradish peroxidase staining studies have shown that neurons in the visual cortex are organized according to local-global structure.
B)single-cell recording studies of the visual cortex have revealed the presence of sinusoidal gratings in the brain.
C)many visual neurons have receptive fields that are maximally excited by bars of light of particular widths.
D)most neurons in the visual cortex have receptive fields that are maximally sensitive to low-contrast stimuli.

The observation that many visual neurons have receptive fields that are maximally excited by bars of light of particular widths supports the idea that the visual system carries out Fourier analysis, as this property is consistent with the processing of spatial frequencies. The neurons in the visual cortex are thought to act as filters that extract different spatial frequency components from the visual input, similar to the way in which Fourier analysis decomposes a complex waveform into its constituent sinusoidal components.
