Vision and Reality

Submitted by Serendip Visitor on Sat, 04/10/2010 - 9:23pm.

From a physiological point of view, I really enjoyed learning about the eye and how the different parts function together to allow us to be able to see. Like with action potentials, this course is teaching me to appreciate all of the extremely complex mechanics that go into what we take for granted as simple actions such as seeing and vision.

The idea that our brain has a 'blind spot' has always sort of creeped me out. While I admit it is a useful evolutionary feature for our brains to fill in the missing pieces and make assumptions, I can't help but worry about what would happen if it were wrong? Could there be thing around us that we are not seeing at all? I wonder if this has anything to do with our incapacity to view things that are on different wavelengths. Our brains are just not equipped for all types of tasks.
