Scattergram of eye movement (EM) density.
The horizontal axis indicates the gestational weeks and the vertical axis indicates the EM density. The solid line indicates the average of each group. Open arrows indicate the statistically defined critical points.

Scattergram of eye movement (EM) burst density.
The horizontal axis indicates the gestational weeks and the vertical axis indicates the EM burst density. The solid line indicates the average of each group. Open arrows indicate the statistically defined critical points.
Fig 4.
Scattergram of density of eye movements (EMs) in EM bursts.
The horizontal axis indicates the gestational weeks and the vertical axis indicates the density of EMs in EM bursts. The solid line indicates the average of each group. Open arrows indicate the statistically defined critical points.
