Running Head: VISION AND PERCEPTION:OVERVIEW Vision and Perception Introduction to Psychology Perception and sensation play a major role in our everyday lives. We need both perception and sensation to manage our interactions with everything around us. Of particular importance is our ability to sense and perceive sight. Without vision‚ we would not be able to see anything around us and without perception we could not interpret what we were seeing. Microsaccades are an important function

"lightning-fast moves and shocking electric effects". Pikachurin was initially identified in a microarray analysis of gene expression profiles of the retinas of wild-type and Otx2 knockout mice. A RT-PCR analysis was used to confirm that Otx2 regulates the expression of pikachurin‚ it was known because there was an absence of expression of pikachurin in the Otx2 mice retina‚ so it indicates that Otx2 regulates pikachurin. The localization of pikachurin to synaptic cleft in the photoreceptor ribbon synapse was

side. This causes blurred vision because the light that hits the retina at the back of the eye isn’t refracted properly‚ thus causing an imperfect image. Lenticular astigmatism is when the lens‚ not the cornea‚ has variations in its curvature. This type of astigmatism is quite similar to the corneal astigmatism‚ the only difference is that it occurs in the lens and not the eye. This also causes the light to imperfectly reach the retina‚ which again causes the image to be blurry. In most cases people

in the inner eyelid where oily secretions are released to help lubricate the eye. A cataract is a clouding of the eye’s natural lens‚ which lies behind the iris and the pupil. The lens works much like a camera lens‚ focusing light onto the retina at the back of the eye. The lens also adjusts the eye’s focus‚ letting us see things clearly both up close and far away. The lens is mostly made of water and protein. The protein is arranged in a precise way that keeps the lens clear and lets light

The Five Sense Organs in Human Beings The sense organs — eyes‚ ears‚ tongue‚ skin‚ and nose — help to protect the body. The human sense organs contain receptors that relay information through sensory neurons to the appropriate places within the nervous system. Each sense organ contains different receptors. • General receptors are found throughout the body because they are present in skin‚ visceral organs (visceral meaning in the abdominal cavity)‚ muscles‚ and joints. • Special receptors include
