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.

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....

Parallel Processing

Parallel Processing

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...

Color Vision

Color Vision

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.

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.

Background:

High-level cortical areas are known for timing functions.
Recent research reveals timing activity in early visual cortex.
This activity is modeled via reinforcement learning signals.

Purpose of the Study:

To investigate the role of visual cortex in interval timing.
To test hypotheses derived from reinforcement learning models of timing.
To explore the properties and behavioral relevance of visual cortex timing.

Main Methods:

Observing timing activity in the visual cortex.
Formally modeling this activity using reinforcement signals.
Conducting experiments to test the necessity and sufficiency of reinforcement signals.
Analyzing interval timing behavior for adherence to the temporal scalar property.
Perturbing visual cortex activity during timing tasks.

Main Results:

Timing activity is present in the early visual cortex.
Reinforcement signals are necessary and sufficient for this timing activity.
Visual cortex interval timing adheres to the temporal scalar property.
Perturbations of the visual cortex cause lawful shifts in timing behavior.

Conclusions:

The visual cortex is a critical substrate for learning and expressing visually-associated temporal expectations.
These temporal expectations influence behaviorally-relevant actions.
Findings support a broader role for sensory cortices in temporal cognition.
