Figure 6.

A comparison of behavioral and neural acuity development in macaque monkeys. Behavioral spatial resolution data are plotted as a function of age, as in Figure 2 (filled circles) along with neural measures of acuity: Nyquist frequency of the cone mosaic (open circles, data from Kiorpes et al., 2003), characteristic spatial frequency of parvocellular LGN neurons (open squares, data from Movshon et al., 2005), spatial resolution of V1 neurons (black triangles, data from Kiorpes and Movshon, 2004a), and spatial resolution of V2 neurons (gray triangles, data from Maruko et al., 2008). The overall extent of neural development is small compared with behavioral maturation. Redrawn from Kiorpes (2015).
