Relationship between the spontaneous firing rate and the cell response properties. a. Combined selectivity to orientation, spatial frequency and direction of motion (0: non selective, 1: very selective). b. Orientation tuning measured as circular variance (0: sharp tuning, 1: broad tuning). c. Receptive field latency measured by reverse correlation. d. Spatial frequency tuning measured as half-width at half-height (octaves). e. Response amplitude measured as the first Fourier harmonic of the PSTH. f. Directional selectivity (0: non directional, 1: very directional). g. Measurement of on/off overlap (0: no overlap, 1: high overlap). h. Measurement of on/off overlap (0: high overlap, >0: increasingly less overlap). i. Response amplitude measured as the mean firing rate. j. F1/F0b. k. Contrast that generated half of the maximum response. l. Measurement of on/off overlap (−1: no overlap, +1: high overlap). m. Measurement of on/off overlap (0: overlap, π : no overlap). n. Measurement of on/off overlap (<1: increasingly less overlap, 1: overlap). o. Peak of spatial frequency tuning.
