    address this question: “Propose a possible explanation on why the light caused depolarization of the off-center ganglion cell?” we first have to describe the structure of the center -surround in the receptive fields of retinal. In the receptive field‚ there are cone photoreceptors that communicate with On and Off center bipolar cell and finally On and Off center ganglion cells that carry the action potential to the cortex. When light comes to the retina (eyes) it causes closing of channels in the

    the functional role of amacrine cells in retinal dynamics. In this thought paper I will argue that together with the bipolar and ganglion cells‚ the amacrine cells operate in a parametric system similar to the feedback and feedforward systems found in motor control. In order to determine the role of the amacrine cells they needed to determine the method of bipolar convergence and divergence in ganglion cells. When stimulated individually‚ two different bipolar cells were able to elicit distinct post

    him or her having Sickle Cell Disease. What this is is it’s a disease that is genetically inherited and it involves the red blood cells. Mutations in the HBB gene cause this disease. This disease is inherited in an autosomal recessive pattern‚ which means both copies of the gene in each cell will have mutations. The parents of offspring with an autosomal recessive gene each carry one copy of the mutated gene. The blood cells form an abnormal crescent shape (normal cells are in a disk form). The

    The effect of temperature on beet cell membranes Introduction: A cell membrane of a beet (Beta Vulgaris) is made up of a phospholipid bilayer with embedded proteins and cholesterols. The membrane is responsible for organizing the cell‚ protecting it from the exterior environment‚ as well as responsible for regulating what goes in and out of the cell though it’s protein channels and “selectively permeable” bilayer. (Campbell‚ Reece‚ Taylor & Simon‚ 2006‚ p. 79-80) When this membrane is damaged

    The question of whether cell phones should be allowed in schools has been hotly debated over the years. The reality is‚ bans on cell phones are hard for schools to enforce. A 2010 Pew Internet & American Life Project study found that 65 percent of cell-owning teens at schools that completely ban phones bring their phones to school every day anyway. Most schools now allow students to have cell phones but try to require them to be turned off during class because they can be disruptive and distracting
