| Visual system | Accessed | visual systemthe components of the nervous system and the nonneural apparatus of the eye that contribute to the perception of visual stimulation. The anterior structures of the eye, such as the cornea and lens, focus light on the retina, which transduces photons into neural signals. These are transmitted via the optic nerve and optic tract to nuclei in the thalamus and brainstem. These in turn transmit the signals either to the visual areas of the cerebral cortex for hierarchical processing and conscious analysis or directly to motor centers in the brainstem and spinal cord to produce eye movements. |

| Magnocellular system | APA Dictionary of Psychology Accessed | magnocellular systemthe part of the visual system that projects to or originates from large neurons in the two most ventral layers (the magnocellular layers) of the lateral geniculate nucleus. It allows the rapid perception of movement, form, and changes in brightness but is relatively insensitive to stimulus location and color. See also M-cell. Compare parvocellular system. |
| Parvocellular system | APA Dictionary of Psychology Accessed | parvocellular systemthe part of the visual system that projects to or originates from small neurons in the four dorsal layers (the parvocellular layers) of the lateral geniculate nucleus. It allows the perception of fine details, colors, and large changes in brightness. The parvocellular system is expanded in primates compared to that in other animals; it conducts information relatively slowly because of its small cells and slender axons. See also P-cell. Compare magnocellular system. |
