Each of our _____ has specialized receptors that are sensitive to a particular kind of energy .
To transduce "Convert" energy is...
Receptors ______ energy.
Light enters the eye through an opening in the center of the iris called the...
The pupil is focused by the lens (adjustable) and the cornea (not adjustable) and projected into the...
The retina is the rear surface of the eye, which is lined with ______ receptors.
In the vertebrate retina, messages go from receptors to the back of the eye to _______ cells, located closer to the CENTER of the EYE.
The bipolar cells send their message to the ______ cells, located still closer to the center of the eye.
The retina has 3 layers:
What is the nerve that carries info from the EYE to the BRAIN?
Vision : Audtion :: Optic Nerve :: _______ _____
This controls the ability of the ganglion cells to respond to shapes, movements, or other visual stimuli.
The point at which the ganglion cells leaves (also where the blood vessels enter and leave) is the ______ ______ because it has NO receptors.
Blind spot does not have ______ cells or process and information.
Receptors are to
_____ abundant near the fovea, less active in DIM light, more USEFUL in bright light, and essential for color vision.
Which are abundant in the periphery of the human retina, respond to FAINT light (White Light) but are not useful in daylight bc bright light bleaches them.
1 Cone = 1 Ganglian =
1 Rod = Many Ganglian =
Not Detailed Vision
Rods & Cones have ________ that release energy when struck by light.
The perception of color is
Wavelength of Light
Trichomatic Theory by Young-Helmholtz has 3 types of cones:
In the thalamus region of the brain is the Lateral _______.
3 Types of Ganglion Cells:
Type of Ganglion Cell that is near the fovea, a lot of cones result in color:
"sensitive to cones - color vision"
Type of Ganglion Cell that is near the retina and has large cell bodies:
Type of Ganglion Cells that is near the retina and has small cell bodies:
3 Types of Cells in the Visual Cortex
The type of Cell in the visual cortex that has a fixed zone:
The type of Cell in the visual cortex that do not respond to the exact location of a stimulus (not fixed zone). It is located in the V1 & V2 (Visual Cortex):
The type of Cell in the visual cortex that resemble complex cells with one exception; an end-stopped cell has a strong inhibitory area at one end of its bar-shaped receptive field (AKA End-Stopped cell):
When Experiences have a particularly strong and enduring influence:
When eyes do not point in the same direction, also called "lazy eye" is:
This stream is the "what" pathway bc it specialize for identifying and recognizing objects:
This stream is the "where" pathway bc it helps the motor system locate objects:
"visual lack of knowledge"
Results from damage in the temporal cortex
