There are amazing processes which goes on before you can see! Your retina performs an array of multiple digital transformations! A recent study by opthalmologists from the University of Tübingen, Germany has discovered that your eye goes digital. What was thought to be continuous analog signals to the retina are really created spikes (action potentials) that represent on-or-off conditions which is the basis of digital programming!
Currently Biology describes a vast amount of complexity where the eye massages its digitized information for the brain.
“Action potentials allow for much faster and temporally more precise signal transmission than graded potentials, thus offering advantages in certain situations…”
“The retina in our eyes is not just a sheet of light sensors that – like a camera chip – faithfully transmits patterns of light to the brain. Rather, it performs complex computations, extracting several features from the visual stimuli, e.g., whether the light intensity at a certain place increases or decreases, in which direction a light source moves or whether there is an edge in the image.”
“To transmit this information reliably across the optic nerve — acting as a kind of a cable — to the brain, the retina reformats it into a succession of stereotypic action potentials – it “digitizes” it. Classical textbook knowledge holds that this digital code – similar to the one employed by computers – is applied only in the retina’s ganglion cells, which send the information to the brain. Almost all other cells in the retina were believed to employ graded, analogue signals. But the Tübingen scientists could now show that, in mammals, already the bipolar cells, which are situated right after the photoreceptors within the retinal network, are able to work in a “digital mode” as well.”
There are at least 8 classes of the bipolar cell patterns that were classified by the researches. Why would this be considered the end of the dogma? Action potentials have been discovered before, but were considered only rare exceptions rather than the norm. The press release goes on to say that the discovery opens up new questions. But as one reads this, evolution is not even mentioned! Normally they just give credit to evolution or just speculate on the spot, but how could they mention it, considering that they were talking about computer cables with digital codes! These concepts as you know are designed by a thought process rather than a mindless one!
This is a classic example of when science improves that leads to astounding discoveries, nature appears more intelligently designed than ever before! The autonomous bipolar cells cannot “know” nor understand what the brain needs. Bipolar cells require pre-programming in order to send vital information to the brain and have the brain understand that vital information so it could react the right way. Formatting of the signal takes place using a code that the brain is able to understand! And it is required to get there fast, that is why digital was the way to go!
The exquisite interaction of parts here, sending digitally-encoded information down a “cable” of sorts, is truly one of the most amazing and mind-boggling things ever discovered! We are not talking about just a camera with a chip; rather we are talking about the whole Photoshop!
So when we look at nature, before we think what we are seeing, just think of how many processes it took to get us to see what we are seeing! There is a quite an amazing list of intermediaries which includes; the cornea, the aqueous humor, the lens, the vitrious humor, the rods and cones, the bipolar cells, the retinal ganglion cells, the optic nerve, and who knows what else which has yet to be discovered, has massaged, transformed and formatted the signal from the initial impingement of photons on the cornea!
