I stumbled across this word and I have never heard of this condition at all
I understand the article and it makes sense but I am having trouble visualizing how it would work. The article states
Since everything I see has movement, it seems hard to relate.
Can anyone give me insight on this condition?
I always thought the opposite was weird. There is a condition where the person is completely absolutely no-more-black blind but can see movement. The reason is that from the eyes, visual signals take two paths to the occipital lobe. The path through the mammalian brain is how we interpret shape, color, etc. The one through the reptilian brain detects movement. This is the sort of vision that makes you instinctively flnch when you see something out of the corner of your eye.
The guy on the PBS show I watched had brain damage that broke the visual path through the mammalian brain but not the reptilian brain so he couldn’t see color or shapes but he could still detect movement. I wonder if akinetopsia comes from a malformation or damage in the lower path and not in the upper path.
Well, precisely! 
From time to time, I’ve read descriptions of various kinds of weird things that can happen when someone gets brain damaged through trauma, stroke, disease, or whatever. I seems like life must get really really weird (and possibly really really uncomfortable) for people like this. For example, split-brain patients, from the description, seem almost to have two separate (and sometimes competing) brains in one head.
