Primary Visual Cortex and Visual Stimuli Patterns

These flashcards cover key concepts related to the primary visual cortex and the patterns of visual stimuli as discussed in the lecture notes.

Lateral Geniculate Nucleus (LGN)

A relay center in the thalamus for the visual pathway, where visual information is processed before it reaches the primary visual cortex.

Primary Visual Cortex (V1)

The region of the brain responsible for processing visual information, located in the occipital lobe.

Receptive Field

The specific area of visual space where a stimulus will alter the activity of a given neuron in the visual system.

On Center, Off Surround

A type of receptive field organization where a visual stimulus in the center activates the neuron while a stimulus in the surrounding area inhibits it.

Off Center, On Surround

A type of receptive field organization where a visual stimulus in the center inhibits the neuron while a stimulus in the surrounding area activates it.

Hubel and Wiesel

Pioneering researchers known for their foundational studies on the visual cortex, particularly in relation to how neurons respond to visual stimuli.

Visual Stimuli Patterns

Different arrangements or designs of visual inputs presented to subjects to study their influence on neuron response in the visual cortex.

Neurons in the Visual Cortex

Specialized cells that respond selectively to various visual stimuli, contributing to visual perception.

Visual Processing

The sequence of operations the brain undertakes to interpret visual information received from the eyes.

Crosstalk between Thalamus and Visual Cortex

The bidirectional communication between the thalamus and the primary visual cortex, influencing perception and processing in the visual system.
