Topic 7: Sensation and Perception

 

 

 
 

Please answer both questions.

1. You are aware that humans lack some animal senses. If we could borrow one from another species, which additional sense would you choose for all of us? What benefits would it offer, and what problems? Some animal senses are amazingly different (http://www.cracked.com/article_18837_7-superpowered-animal-senses-you-wont-believe-are-possible.html)  from ours and others differ mostly in degree (http://www.nms.ac.uk/our_museums/national_museum/explore_the_galleries/natural_world/animal_senses.aspx). Some senses are completely nonhuman (http://animals.about.com/cs/zoology/a/aa061801a.htm)   while others overlap  (http://faculty.washington.edu/chudler/amaze.html) with our abilities.

2.  The retina is unconscious and can’t recognize faces or read a winning lottery ticket, but it’s not just a camera that takes snapshots, either. What kinds of information do you think the retina sends to the brain for further processing? Some animals process images without a cortex (http://www.scientificamerican.com/article.cfm?id=seeing-without-eyes) and some people “see” without some of their cerebral cortex, though with limitations. This is described in the book as blindsight (p. 155), and you can watch it here  (https://www.youtube.com/watch?v=GwGmWqX0MnM). If someone has their sensory receptors but not the related sensory cortex, what abilities would you expect them to lack? Doctors sometimes test for this   (http://www.neuroexam.com/neuroexam/content.php?p=41).
