dominant wavelength of a stimulus

Physics; Color science

The wavelength of the monochromatic light that when mixed with a specified achromatic light in suitable proportion yields a match to the stimulus under consideration. Since there ...

electron-volt

Physics; Color science

The amount of energy required to move an electron across a potential difference of one volt. A common unit of energy in physics.

anomalous trichromacy

Physics; Color science

Condition of having three functioning cone types where one or more of the cones has abnormal spectral sensitivity. Anomalous trichromats, like normal subjects, require three ...

hemianopia

Physics; Color science

The loss of visual capacity in one half of the visual field, typically due to damage to primary visual cortex. (Strictly speaking this type of visual field defect is a homonymous ...

magnocellular pathway

Physics; Color science

One of the two main neural pathways from the retina to the primary visual cortex (the other is the parvocellular pathway). The magnocellular pathway is not thought to play an ...

spatially opponent neuron

Physics; Color science

A neuron that is excited (or inhibited) by stimuli in the center of its receptive field and inhibited (or excited) by stimuli in the periphery of its receptive field.

horizontal cell

Physics; Color science

Neurons found in the retina that make widespread synaptic contacts with other retinal neurons and that are thought to play a role in generating the receptive field properties of ...
