Summary
Selective visual attention focuses processing on relevant stimuli, a fundamental cognitive function. This review explores its neural mechanisms, processing alterations, causal basis, and assessment methods.
Area of Science:
- Cognitive Neuroscience
- Neuroscience
- Visual Processing
Background:
- Selective visual attention is a fundamental cognitive function, crucial for primates relying heavily on vision.
- It governs the brain's ability to prioritize relevant visual information for behavioral responses.
Purpose of the Study:
- To review recent advancements in understanding the neural mechanisms underlying selective visual attention.
- To examine how different types of selective attention impact neural processing within the visual system.
Main Methods:
- Review of existing literature on selective visual attention.
- Analysis of studies investigating neural processing alterations due to attention.
- Examination of methods for assessing attentional dysfunctions.
Main Results:
- Evidence suggests distinct neural mechanisms underlie various forms of selective attention.
- Selective attention significantly modulates stimulus processing by visual neurons.
- Current knowledge on the causal basis and assessment of attentional dysfunctions is discussed.
Conclusions:
- Significant progress has been made in identifying neural mechanisms of selective visual attention.
- Key questions remain regarding the precise neural underpinnings of selective visual information processing.

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...

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.

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...

8.6K
The cerebral cortex, the brain's outermost layer, is pivotal in processing complex cognitive tasks, emotions, and various sensory inputs and executing voluntary motor activities. This intricate structure is divided into three primary functional areas: the motor areas, sensory areas, and association areas.
Motor Areas
The motor areas located in the frontal lobe are central to controlling voluntary movements. This region is further subdivided into the primary motor cortex and the premotor cortex....

842
The brain processes sensory information rapidly due to parallel processing, which involves sending data across multiple neural pathways at the same time. This method allows the brain to manage various sensory qualities, such as shapes, colors, movements, and locations, all concurrently. For instance, when observing a forest landscape, the brain simultaneously processes the movement of leaves, the shapes of trees, the depth between them, and the various shades of green. This enables a quick and...

1.8K
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.
