FIG. 2. — A: frequency histograms showing the distribution of the firing rate of individual V1 neurons during the peak transient firing (R_max, □) and during the sustained firing (R_min, ). B: comparable frequency histograms for V2 neurons. C: frequency histograms showing the spontaneous activity of individual V1 neurons () and their overall responses to 640-ms step stimuli (□). D: comparable frequency histograms for V2 neurons. The median values (numbers) are indicated with ▾ and | for each age group. 2W: 2-wk-old-infants, 4W: 4-wk-old-infants.
