- Do blind people dream in visual images? How can we differentiate so many different foods if we can only taste four flavors on our tongue: sweet, bitter, sour, and salty? Is human blood ever any color other than red? Why do camera flashes make your eyes turn red?arrow_forwardIf you place a plain, dry cracker in your mouth, you will slowly notice a sweet taste. Why?arrow_forwardWhat could be the reason why vitamin A is essential for visual acuity? Select the correct response: • It is converted into the pigment in the iris that absorbs harmful UV radiation. • It is an integral part of the visual pigment in the retina called rhodopsin. • It neutralizes free radicals that can damage the retina of the eyes. • It serves as lubricant in the vitreous humor of the eyes.arrow_forward
- 1) Those with blindsight think they can't see but can react to visual stimuli anyway. Why? they are faking being blind: they can see just fine, just like us the part of the cortex that controls conscious vision is still intact because the part of their visual system that controls visual reflexes is still intact because their eyes work fine and they also don't actually have any brain damage 2) Those with blindsight think they can't see but can react to visual stimuli anyway.

- Colour blindness can result from the loss of specific types of cones, or it can occur in individuals having fewer cones of a given type. An individual has 50% less than the normal number of green cone photoreceptors in his or her retina. How would this affect his or her vision? a. This person has night blindness. He or she should start to eat more carrots to replenish the stock of retinal molecules in the retina. b. This person will have difficulty adapting to varying light levels. His or her cone receptors take much longer to adapt in a brightly lit area. c. This person does not have a colour blindness because no green cone photoreceptors are in the retina; only red, yellow, and blue photoreceptors exist. d. This person has a mild green colour blindness. He or she cannot see green colours very clearly and has difficulty distinguishing colours involving green hues.arrow_forwardTaste receptors: a) extends through small openings called taste buds b) has axons that extend directly to the taste center of the cerebral cortex c) lacks axons but releases nerve transmitters when stimulated d) just sitting on the tonguearrow_forwardThink about the color purple. I’m sure you are imagining a variety of shades of the color of royalty from a deep violet to a subtle lavender and everything in between. But while it seems to be a fairly straightforward concept, describing a color is a much more daunting task. First, we need to understand what color is and how people perceive color. To further confound matters, color vision from one person to another is not set in stone; the variety and combination of the cells in the back of your eyes will determine the colors you see, and the way you’ve experienced the world will teach you how to describe them to others. What started out as a concept that most children learn before they set foot in a schoolroom has quickly morphed into an immensely complex set of issues. To help address some of the complexity of sight and color perception, we will approach it from a cellular level to understand how light can be transduced into a nervous signal.
