Key Concepts

Saccadic Suppression

This is a process during rapid eye movements (saccades) where the brain momentarily reduces the sensitivity to incoming visual information. The suppression prevents the perception of blurring or motion that would otherwise occur due to the rapid shift of the retina over the visual scene.

Corollary Discharge

Often termed as the efference copy, this is an internal signal that copies the motor command of the eye movement. It is used by the brain to predict the sensory consequences of those movements, effectively helping to offset the expected changes in visual input.

Visual Stability

This concept refers to the brain’s ability to create a consistent and stable perception of the environment despite the constant motion of the eyes. By integrating motor signals with sensory data, the visual system maintains a steady and coherent representation of the external world.
