A&PII: explain why the human visual field has a blind spot
Homework Answers
ANSWER :
A blind spot or scotoma is found in the visual field of retina in human eyes due to absence of photoreceptor cells (rods & cones) in that area, and where optic nerves and blood vessels leave to the brain. Hence no image is possible to form in that part of visual field of retina.

. Answer the following questions about the blind spot that can be found in each human eye (you may draw a figure if it helps you explain the blind spot but be sure you label this figure clearly) Specify the names of the two layers of the retina? Describe where the photoreceptors are located (be specific) AND if they are more superficial or deep to the majority of the nervous tissue of the eye. Where is the blind spot located...

Identify the INCORRECT statement about the physical structure of the visual system: Incoming light passes through the photoreceptor cell body before being absorbed in the outer segment At the fovea, the other retinal cell layers fall away creating a small dip to let light fall directly on the photoreceptor cells The passage of the optic nerve through the retina causes a blind spot in the visual field The fovea has more rod cells than cone cells

1. Measure the blind spot by closing your right eye, fixating on the X, and move your head closer or further until you can get the circle to disappear. Then do some geometry to find the visual angle of the blind spot. Measure the distance from the X to the center of the circle. Then measure the distance of the X from your left eye when the circle has disappeared. Now compute the visual angle as seen in...
explain why the following formula for visual angle is correct: tan(visual-angle/2) = (object width)/(2*distance)

Robert Dougherty and colleagues conducted an experiment to determine the magnification factor in the human visual cortex. Describe the experiment by answering the following questions: What research tool was used to get their results? Describe the stimuli presented to the subject. What kind of stimulus was used? How were stimuli presented to the subject? Create a diagram if it helps to explain. What were the findings? What does these findings tell us about visual acuity?
