SMOOTH PURSUITS Meaning and
Definition
-
Smooth pursuits, also known as smooth pursuit eye movements, refer to the tracking movements of the eyes that occur when someone follows a moving target. It is a voluntary, coordinated, and smooth motion of the eyes that enables individuals to visually track a moving object or person.
During smooth pursuit movements, the eyes smoothly and continuously follow the target's motion, maintaining a stable and clear image on the fovea, the central part of the retina responsible for sharp vision. These movements are often associated with a person's intention to visually explore or keep track of a moving stimulus. For example, when watching a bird fly across the sky or following a bouncing ball, smooth pursuits enable us to maintain visual contact with the target.
Smooth pursuit movements rely on the coordination between the visual system, oculomotor system, and the brain. Neurons in the visual cortex receive signals from the moving stimulus and send them to the brainstem, which then activates the oculomotor system to control the eye muscles. This coordination ensures that the eyes smoothly track the motion of the target.
Smooth pursuits can vary in speed and accuracy depending on factors such as the velocity and predictability of the moving object. Impairments in smooth pursuit movements can occur in certain neurological or vision disorders, affecting a person's ability to precisely track moving targets.
