Tiny Vessels
Like all organs, our eyes rely on a complex network of blood vessels in order to function properly. Vessels supply blood to the retina, a thin layer of cells in the eye (shown here as pink, blue and red layers) that convert the light we see into electrical signals. If these tiny vessels develop badly, they can block the retina’s cells and cause vision loss. Scientists are studying a type of protein whose job is to keep a close eye on these vessels, and prevent them from growing awry.
The team found that abnormal blood vessels were more likely to develop in mice that don’t have this protein in their retinal cells. Regions in their retina where this protein was missing are shown in bright green. This research helps us understand how specific proteins in the eye are there as a safeguard against vascular disease and ultimately, blindness.

Very good
ReplyDeleteThis is very interesting thanks, I was reading about the eyes in one of my books last night. We don't see with our eyes, they work the same as cameras they take a photo then send the image to our subconscious. Our intelligence is in our souls not our brains. Amazing to think that as quantum physics states atoms change as to how we perceive them, thats a whole other story but watch this little girl she is amazing bless her! https://www.youtube.com/watch?v=ZtLkzg8bFgA
ReplyDeletehaylee turner -- at least some visual processing is done within the eyes themselves, in the bipolar nerve cells and retinal ganglia. It's probably accurate to consider the retina as part of the brain. http://neuroscience.uth.tmc.edu/s2/chapter14.html has a ton of information if you're curious.
ReplyDeleteAnd possibly more in a few cases, Maria Ortiz -- https://en.wikipedia.org/wiki/Tetrachromacy#Human_tetrachromats
ReplyDeleteJohn Bump thanks x
ReplyDeleteJohn Bump yes thats what I said they work like a camera and look what goes into making one of those, its just that people are under the misconception that the eyes are the only reason we see and process what the image does and is but thats not true, the eyes take the pic,amazing as that and they really are, it then sends the image to the subconscious to process
ReplyDeleteMaria Ortiz what do you mean the so called dark matter today scientists call it that because they don't believe they have a soul lol the same scientists that are dissecting brains trying to look for a thought lol. Our intelligence is in our soul not our brains the sooner they work that out the better. They will learn one day. Check this video out https://www.youtube.com/watch?v=ZtLkzg8bFgA amazing little girl, turns out we don't even need eyes x
ReplyDeleteOh, let's get to the bottom of this...The lens focuses light through the vitreous humor. The retina receives the image that the cornea focuses through the eye's internal lens and transforms this image into electrical impulses that are carried by the optic nerve to the brain.
ReplyDeleteWhen it comes to optical illusions, what the human eye sees is interpreted by the brain in a way that differs from objective reality.
+Corina Marinescu yes your spot on and that tx book is also spot on but I already said, intelligence is in our soul not our brain.
ReplyDeleteCome again...that's phony science and a waste of time, the subject is closed.
