Vision

Vision

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.

Anatomy of the Eyeball

Anatomy 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...

Visual System

Visual 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...

Motor and Sensory Areas of the Cortex

Motor and Sensory Areas of the Cortex

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....

Photoreceptors and Visual Pathways

Photoreceptors and Visual Pathways

At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

The Retina

The Retina

The retina is a layer of nervous tissue at the back of the eye that transduces light into neural signals. This process, called phototransduction, is carried out by rod and cone photoreceptor cells in the back of the retina.

Summary

Omitted stimulus potentials (OSPs) reflect prediction errors. This study found that omitted visual stimuli elicit a visual mismatch negativity, suggesting distinct processing pathways compared to actual visual stimuli.

Neuroscience
Visual Perception
Cognitive Neuroscience

Background:

Omitted stimulus potentials (OSPs) are brain responses to the absence of expected stimuli.
OSPs are theorized to represent prediction errors in sensory processing.
The role of the early visual cortex in OSP generation remains unclear.

Purpose of the Study:

To investigate the early visual cortex's involvement in generating OSPs.
To determine if omitted visual stimuli evoke spatially specific brain responses.
To differentiate the processing of omitted versus presented visual stimuli.

Main Methods:

Event-related potentials (ERPs) were recorded from 33 participants.
Checkerboard stimuli were presented in alternating upper and lower visual fields.
Stimuli were omitted in 10% of trials to elicit OSPs.

Main Results:

Presented visual stimuli evoked a retinotopic C1 component.
Omitted stimuli did not elicit retinotopic responses.
A visual mismatch negativity (vMMN) was observed, larger for lower than upper visual field omissions.

Conclusions:

The early visual cortex does not process omitted visual stimuli in a retinotopic manner.
OSPs, specifically vMMN, suggest distinct neural pathways for processing absent visual information.
Prediction error signaling in the visual system may involve specialized processing streams.
