The 6 million receptor cells located mostly in the center of the retina that transduce light waves into neural impulses, thereby coding information about light, dark, and color (p 112)
Cone-shaped, light-sensitive receptor cells in the retina that are responsible for sharp focus and color perception, particularly in bright light
Photoreceptors in the retina that contain light-sensitive pigments capable of initiating the process of photopic vision
Speaker cone Paper piston that pushes air in or out of a speaker cabinet When a speaker quits working it probably needs to be re-coned Submitted by Karl Kuenning RFL from Roadie Net
Devices for facilitating the loading, positioning and lashing of containers The cones insert into the bottom castings of the container Synonym: Locating pin
a type of retinal receptor that is active in daylight (photopic) conditions The three different types of cone found in the human retina provide the basis for colour vision See also rod
Photoreceptor cells located in the fovea of the retina and responsible for color (photopic) vision
One of the two major classes of photoreceptors, the other being rods Cones are less sensitive to light than rods and mediate color vision
located inside the retina, these are light- and color-sensing cells in the macula which shed their outer tips during the day These are responsible for central vision
the cells of the retina that respons to bright light and are responsible for color vision; there are three types of cones: red, blue, and green
The specialized photoreceptors in the human eye that allow us to discriminate between different wavelengths of light Our eyes contain three distinct types of cones, designated the L, M, and S cones because they are primarily sensitive to long, medium, and short wavelengths of light (The other type of photoreceptor in the eye are known as rods They are primarily used in low-light and peripheral vision and do not contribute to color vision )
Highly specialized conical or flask-shaped outer segments of the visual cells, which, with the retinal rods, form the light-sensitive elements of the retina

A set of small triangular pyramids of clay mixtures and fluxes so graded that they represent series of fusion points The degree of heat is measured in kiln by observing which of various cones have bent over
Small, elongated, three sided pyramids made of materials designed to melt at a specific temperature Designed to melt at the same temperature as the glazes used Cones indicate the progress of the melting Cones are placed just inside the kiln during a firing so they can be seen through a peephole The cones are one-time use only, and are available for a wide range of temperatures They are numbered according to the temperature at which they melt When discussing the temperature to which a piece/glaze is fired, reference is usually made to the cone used The low fire range usually includes cones 06 through 01, intermediate fire includes cones 1 through 6, and high-fire includes cones 7 and up See also firing, kiln
