Seeing, Remembering, and Understanding Part Two
Part one dealt with how the brain’s primary and secondary visual cortices organize information that is coming from the eyes. What if you have to do something, like finding two books on different shelves after you set them aside? How do the eyes and brain work together in a situation like the one just described? […]
Seeing, Remembering, and Understanding Part One
How do the eyes and brain work together when it comes to categorizing and memory? For example, you go to the supermarket and you see some carrots. Do you think of the carrots as an ingredient for a salad or are they part of a snack tray? Or imagine seeing two books on different shelves […]
Navigating Within Space & Restoring Vision After a Stroke
Have you ever considered the amount of information that goes from your eyes to the brain, so that you can navigate through an area, be it in your home or a walk to the store? Also, if vision is lost as a result of stroke, can it be restored? Both deal with taking information in […]
Cognitive Function and The Eyes Part One
It has been said that the eyes are the front of the brain, especially since 80 percent of learning takes place via what we see. How does that happen and is it possible to utilize retinal imaging to diagnose age-related brain disorders? As always, researchers are studying these things and this is what was found […]
Babies and Computers and Vision—Oh my!
Our eyes are taking in a lot of information when we see something within milliseconds of turning our head to the object in question. How does that happen? What are the internal mechanisms that lead to our being able to differentiate between two shades of green or know the difference between a pen and a […]
Visual Processing Part Two
Since it was identified which cells do what for vision, the next question is what part of the brain is in charge of processing visual information? Vision is more complicated than it seems. For the longest time, it was thought that vision was a matter of an image that is cast on the retina and […]
