Summary
Human vision remains stable during rapid eye movements (saccades) due to neuronal mechanisms that address image displacement and blurring. This review explores advances in understanding these brain processes using monkey models.
Area of Science:
- Neuroscience
- Vision Science
Background:
- Human vision is stable despite saccadic eye movements.
- Saccades cause retinal image displacement and blurring, posing challenges to visual stability.
Purpose of the Study:
- To review advances in understanding the neuronal mechanisms of visual stability during saccades.
- To explore how the brain compensates for saccadic displacement and suppression.
Main Methods:
- Neuronal recording and inactivation studies in monkey models.
- Analysis of neuronal activity related to eye position and visual input.
Main Results:
- Identified neuronal candidates for saccadic displacement compensation, including shifting receptive fields and eye-position-modulated neurons.
- Highlighted established mechanisms for saccadic suppression, such as visual masking and corollary discharge, with identified neuronal correlates.
Conclusions:
- Neuronal mechanisms involving frontal and parietal cortex neurons, gain field neurons, and real position neurons contribute to visual stability.
- Corollary discharge and visual masking are key for saccadic suppression, with neuronal underpinnings being elucidated.

01:26Visual System
Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

01:24Vision
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.
01:29The Vestibular System
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.
01:15Depth Perception and Spatial Vision
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.
01:20Anatomy of the Eyeball
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...
01:22Indirect Motor Pathways
The indirect motor or extrapyramidal pathways originate in the brainstem, the lower portion of the brain that connects it to the spinal cord. They consist of several distinct tracts, each with specialized functions. The four main tracts of the indirect motor pathways are the vestibulospinal tract, the reticulospinal tract, the tectospinal tract, and the rubrospinal tract.
The vestibulospinal tract originates in the vestibular nuclei of the brainstem. The vestibular system detects changes in...
