Retina print that page

Edge-detection-2

The vertebrate retina is a light-sensitive tissue lining the inner surface of the eye . The optics of the eye create an image of the visual world on the retina , which serves much the same function as the film in a camera. Light striking the retina initiates a cascade of chemical and electrical

The retina is a thin layer of light sensitive tissue on the back wall of the eye. The optical system of the eye focuses light on the retina much like light is focused on the film in a camera. The retina translates that focused image into neural impulses and sends them to the brain via the

Rod cell print that page

Rods are a little narrower than cones but have the same structural basis. The pigment is on the outer side, lying on the pigment epithelium. This end contains many stacked disks. Rods have a high area for visual pigment and thus substantial efficiency of light absorption. Because they have

Retinal ganglion cell print that page

A retinal ganglion cell (RGC) is a type of neuron located near the inner surface (the ganglion cell layer ) of the retina of the eye . It receives visual information from photoreceptors via two intermediate neuron types: bipolar cells and amacrine cells . Retinal ganglion cells collectively

Retinal scan print that page

A retinal scan is a biometric technique that uses the unique patterns on a person's retina to identify them. It is not to be confused with another ocular-based technology, iris recognition . Contents 1 Introduction 2 History 3 In popular culture 4 Uses 5 Pros and cons
