WebThe retina, a light-sensitive tissue at the back of the eye, contains light receptor cells called rods and cones. Cones allow us to see in bright light and provide our color vision. Primates can have 3 types of cones, each containing a special pigment (a photopigment called opsin) that is most sensitive to a particular wavelength of light. WebThere are currently three known types of photoreceptor cells in mammalian eyes: rods, cones, and intrinsically photosensitive retinal ganglion cells. The two classic photoreceptor cells are rods and cones, each contributing information used by the visual system to form an image of the environment, sight.

Focus Article Explaining the functional differences of rods versus cones

WebCones have greater acuity and rods have lower acuity. Cones connected singly to bipolar cells so brain receives nerve impulses from small area. Rods have a lower acuity because they are connected in groups, to bipolar cells. Rods have higher sensitivity because they are connected in groups (summation). This is called convergence. http://www.ichacha.net/rods%20and%20cones.html diy natural hair clip ins
