Mapping of size and wavelength preference. Determining preferred spatial wavelength and summation field size. Two example recording sites a and b. (A) Interpolated multiple unit activity to stimuli of different sizes and spatial wavelengths. (B) Distribution of 1000 global maxima calculated via the bootstrap method. (C) Mean (green line) and variance (broken line) of preferred spatial wavelength estimates as a function of stimulus size. The green diamond indicates the mean of the distribution from B.
