Fig. 5.

Time course of the depth and direction tuning in single cells. Histograms illustrate the temporal evolution of tuning for the cells tuned in depth only (left), direction only (middle), and both (right) across pairs of consecutive epochs. Each histogram shows the percentage of cells that were depth only (open), direction only (shaded), or both (solid) or that lost their tuning (hatched) in the second of 2 consecutive epochs. Note 1) the high proportion of direction-only cells that lost their tuning and 2) the smaller but significant proportion of direction-only cells that become depth-only in later epochs.
