cortex. When light comes to the retina (eyes) it causes closing of channels in the photoreceptor‚ there is no Ca2+ (calcium) influx‚ therefore‚ no neurotransmitter release (glutamate). While in the dark‚ is the opposite to light‚ channels are open‚ permitting the release of glutamate into the cells. Figure 1‚ briefly shows the process of when light and no light is

Norbert Weiner’s success started early in childhood‚ and his wartime contributions led him to become not only a noted mathematician but also to develop cybernetics. Norbert Wiener showed a remarkable aptitude for learning from an early age. He contributed to WWI war effort and his efforts in constructing anti-aircraft weaponry led him to explore the principle of feedback and its far reaching effect on controlling various systems. When Weiner was first put into the public school system they had

the back of the eye‚ forming an upside-down image to a place where a visual image is created. This place is called the retina‚ when the photocells are hit by light images‚ they become activated. If the photocells do not have a reflection of a light‚ they remain the same. In general terms we have knowledge of the image as a pixelate map of activated and non-activated on the retina. Each photocell have a nerve that connects to a precise area in the visual cortex of the brain. When any photocells becomes

Light then then passes through the lens which focuses the light on the retina (made of rods and cones). The retina turns light into nerve impulses and sends it to the brain through the optic nerve. 2.
