Scientists in Montreal have identified a key mechanism involved in the growth of nerve cells that are critical to mediate binocular vision, which allows people to see the world in three dimensions.

Binocular vision disorders encompass a range of conditions that impair the coordinated function of the eyes, detrimentally affecting the ability to focus, process depth and maintain visual comfort.

A figure from the research shows the same section of neural dendrite at days 1, 5 and 10 of imaging. Arrows indicate spines that will be lost by the next imaging day, or that were added by that day.
