Rods and Cones
Rods and cones are this kind of receptor
What is a photoreceptor
the process whereby the eyes become less sensitive to light
What is Light adaptation?
The target cell's detection of a signal molecule coming from outside the cell.
What is reception?
these cells in the retina respond to light
What are Photorecptors
The process that occurs when The rods and cones transform electromagnetic energy
What is transduction?
retinal receptor cells that are concentrated near the center of the retina and that function in daylight or in well-lit conditions. The cones detect fine detail and give rise to color sensations.
What are Cones?
Dark adaption occurs in this luminance range
Scotopic
conversion of one form of energy into another. In sensation, the transforming of stimulus energies, such as sights, sounds, and smells, into neural impulses our brains can interpret.
What is transduction?
This pigment is found in rods
what is rhodopsin?
This kind of vision is used when both rods and cones are used
mesopic vision
The process in which the eyes become more sensitive to light
What is dark adaptation?
Feature Detectors are specialized cells that break up the image. Feature detectors are cells that respond to lines of specific lengths or angles independently. Both the optic nerve and the primary visual cortex are affected.
What is selection?
Step number 2 in the visual process
What is transduction?
This is responsible for visual information
* Think of 3 types
This is responsible for visual information
* Think of 3 types
Outer segment
Connecting cilium
Inner segment
Nuclear segment
Synaptic region
This pigment is needed to see in the light
What is iodopsin?
This adaptation takes many minutes to occur
Dark adaptation
Perceptual constancies, Gestalt principles, and depth and distance signals are some of the visual principles we use to do this.
What is organization?
Rhodopsin contains this vitamin
What is vitamin A?
Phototransduction enables the photoreceptor to encode this stimulus
What is Light Stimulus?
retinal receptors that detect black, white, and gray; necessary for peripheral and twilight vision, when cones don't respond
What are rods?
This happens to the pupils in light adaptation.
Constricting
In order for us to make sense of visual information, it is reorganized in the visual cortex. Perceptual constancies, Gestalt principles, and depth and distance signals are some of the visual principles we use to do this.
What is interpretation?
This person discovered Phototransduction
Who is Hagins
this step in Phototransduction needs a light response in vertebrate photoreceptors
What is Activation of PDE
