I appreciate your desire to take it apart and understand, but I think there are probably people with PhD's who've been working in neuroscience for 20 years who couldn't tell you why it does what it does exactly. I think it is far more complicated than what you are talking about. My guess would be that it has more to do with dominant structure in magnocellular pathways in the lateral geniculate nucleus and whether the right side or the left side dominates the processing of directional movement first. But I really have no genuine idea. It might have to do more with post V1 processing in the occipital lobe. And yes, I just pulled out my three dollar words for the paragraph above, but only with the intention of implying how complicated this actually is, not to try and appear smarter than I am. Also, most of this 'right brain/left brain' stuff is crap and not actually related to the structures of the brain. Its just like all those other tests about what your personality type is, but when you tie the personality types to physical structures, it seems more 'real' or something.
Or...the lateral geniculate nucleus takes the visual information and processes it...then the image makes a switch and we receive different visual information. Really not complicated.
Obviously the red lines overlap in the pictures I drew because I was trying to show the specific way in which you can interpret the box. But, when the lines are all black, it's ambiguous.
All visual information passes through the LGN before V1. I'm not really sure what you are saying because the moment you open your eyes the LGN is processing.
I didn't mean to say that it wasn't complicated in that there is just one explanation as to how it works. I was just saying that how the human eye samles images (it has a very high and accurate sampling rate) has something to do with the process of how the brain interprets images. But that's not the entire story of how the brain works. That is just one area that I have studied in college and wanted to share since I find how our sense of sight works interesting. <<<< Biomedical Engineer, BS here
Ok. If I came across as condescending, then I apologize. I didn't mean to. Also, since you are a biomedical engineer, can you turn me into the 6 Million Dollar Man? 'Cause that would be cool.

I understand that...Ive spent more than enough time doing neuroanatomy. However, my point was that I think you are looking to far into things such as this image having to do more with post V1 processing in the occipital lobe. Either you were just trying to throw some complicated words out or you are looking WAY too deep into this image ...that changes on us and really has nothing to do with what the what the left or right brain is processing.
The image on the right, where her boobs are facing us (perky ones)...her right leg must be broken to angle that way. Or, she's ridiculously flexible (i like).
Your skills are amazing. You could be.... a first grader with capabilities like that! You kept it pretty much inside the line - that's important. But you illustrate the point - the figure is ambiguous, which is the entire reason for the optical illusion. You see the 2D image, your mind automatically tries to attributed 3D qualities to it. But the ambiguity of the shape makes your mind imagine her (and her boobs) twirling in the pattern your brain has a predisposition for.
He... I was just looking around for information on cognative processing of sillouettes and came across this: At least for me it gives me a bit of a headache, I assume screwing with the specialized facial recognition portions of the brain.
THANK YOU!!! Finally, someone who knows what Im talking about. The image changes...oh that felt so good.
