38 Terms

1
Visual Cortex
The part of the brain responsible for processing visual information.
New cards
2
Anisometropia
A condition where each eye has a different refractive power, leading to nearsightedness in one eye and farsightedness in the other.
New cards
3
Astigmatism
An optical defect caused by a deviation from spherical curvature, leading to the blurring of images.
New cards
4
Lateral Inhibition
A process by which lateral connections in the nervous system decrease the activity of neighboring cells, enhancing contrast in visual perception.
New cards
5
Simultaneous Contrast
A visual perception phenomenon where the appearance of a color is affected by the surrounding colors.
New cards
6
White's Illusion
An optical illusion where the perceived brightness of a color is influenced by the colors surrounding it.
New cards
7
Perception
The process of organizing, interpreting, and consciously experiencing sensory information.
New cards
8
Transduction
The conversion of stimuli from the environment into electro-chemical signals in neurons.
New cards
9
Optic Chiasm
The part of the brain where the optic nerves partially cross, leading visual information from each eye to both hemispheres.
New cards
10
Contralateral Visual Field
The visual field that is processed by the opposite hemisphere of the brain.
New cards
11
Ipsilateral Visual Field
The visual field that is processed by the same hemisphere of the brain.
New cards
12
Lateral Geniculate Nucleus (LGN)
A structure in the thalamus that relays visual information to the visual cortex.
New cards
13
Blindsight
The ability to respond to visual stimuli without conscious awareness of seeing.
New cards
14
Center-Surround Receptive Fields
Receptive field organization in which the center and the surrounding areas have opposite effects on neuron response.
New cards
15
Cortical Magnification
The phenomenon where more area of the visual cortex is devoted to processing foveal regions than peripheral regions.
New cards
16
Simple Cortical Cells
Neurons that respond to bars of light and are sensitive to the orientation of the stimulus.
New cards
17
Complex Cortical Cells
Neurons that respond to bars of light, particularly sensitive to the direction of movement.
New cards
18
End-Stopped Cortical Cells
Neurons that respond to moving lines of a specific length and to corners or angles.
New cards
19
Feature Detectors
Neurons that respond selectively to specific features of visual stimuli, such as orientation or movement.
New cards
20
Selective Adaptation
The reduction in neural firing in response to a frequently presented stimulus.
New cards
21
Neural Plasticity
The ability of neurons in the brain to change and adapt as a result of experience.
New cards
22
Retinotopic Map
A spatially organized mapping of visual input from the retina to neurons in the brain.
New cards
23
Depth Perception
The ability to perceive the world in three dimensions and judge the distance of objects.
New cards
24
Ocular Dominance
The preference of visual processing in one eye over the other.
New cards
25
LGN Layers
The organization of the lateral geniculate nucleus into layers, with different layers processing inputs from different eyes.
New cards
26
Parvocellular Cells
LGN neurons that process color and fine detail, typically associated with P-type ganglion cells.
New cards
27
Magnocellular Cells
LGN neurons that are larger and process motion and depth, typically associated with M-type ganglion cells.
New cards
28
Retina
The light-sensitive layer of tissue in the back of the eye that converts light into neural signals.
New cards
29
Visual Receiving Area
The part of the brain where visual information is initially processed before being sent to higher-level areas.
New cards
30
Optic Nerve
The nerve that transmits visual information from the retina to the brain.
New cards
31
Visual Pathway
The route visual information takes from the eye to the visual cortex in the brain.
New cards
32
Neurons in V1
Neurons found in the primary visual cortex that process visual input and contribute to perception.
New cards
33
Visual Cortex Damage
Injury to the visual cortex that can result in loss of visual perception despite the eyes being functional.
New cards
34
Selective Rearing
An experiment that examines how exposure to specific stimuli affects neural response properties.
New cards
35
Contrast Threshold
The minimum amount of contrast required for a subject to perceive a stimulus.
New cards
36
Psychophysical Experiment
An experiment designed to study the relationship between physical stimuli and sensory perception.
New cards
37
Gratings
Patterns of stripes used in vision experiments to examine perception.
New cards
38
High-level Processing
Advanced stages of visual processing that involve object recognition and conscious perception.
