The laboratory of researcher Eloísa Herrera has discovered that during the development of the brain's visual areas, the two retinas communicate with each other temporarily through nervous projections. This connection is important for synchronizing and aligning the representation of the two images from the eyes in the visual cortex, which ensures they can merge coherently.
Furthermore, in the article published in the journal Current Biology, the researchers describe the molecular mechanisms that lead to the creation of the temporary projections between both retinas, which disappear once the visual circuits have developed, as they are no longer necessary for the processing of the visual information in the adult.
Origins - Cinema - Century - People - Possibility
From the origins of cinema in the late 19th century, people have experimented with the possibility of creating films that emulate the human three-dimensional vision. To achieve this, it was necessary to record the movie simultaneously with two slightly separated cameras aligned in a very accurate way to minimize the unpleasant experience of double vision.
The technical issue the pioneers of cinema found to create 3-D images was, essentially, the same that animals with three-dimensional vision must solve to couple the images registered by the right eye and the left eye. The retina, located in the internal posterior part of the eyeball, has a sensitive surface composed of photoreceptors, which is similar to the pixel map of a digital camera. The retina is much more accurate, as the human eye has around 105 megapixels of resolution. The cells in charge of sending all this information to the brain are those called ganglion cells, each one of which only "sees" a minuscule fraction of the visual field—one pixel. Collectively, they create an organised map that...
