                 But is it possible for us to have any preference in the completion process within the brain?
             Ramachandran also answers this question:

                 Perceptual filling in is very different. When you fill in your blind spot with a carpet design, you don’t have
                 such choices about what fills that spot; you can’t change your mind about it. Perceptual filling in is carried
                 out by visual neurons. Their decisions, once made, are irreversible: Once they signal to higher brain centers

                 “Yes, this is a repetitive texture” or “yes, this is a straight line” what you perceive is irrevocable.    79

                 When we look at a table, our visual system first acquires information about the edges of the table.
             And a representative picture resembling the table’s outline forms in our minds. Following this, the
             system then selects the color and texture of the table. These are some of the essential elements for the
             process of “completion.” After this information has been obtained, the brain makes a general estimate
             regarding the image before it. The brain does not need to examine every detail of that image and enter

             into detailed computation. It creates images based on “guesswork.”               80
                 Therefore, the brain produces an illusion that we believe to exist. The image in the blind spot is not
             a true image of what is in front of us; yet we are unaware of this. Interestingly, however, we have no

             evidence that the entire image is true. The image in the blind spot, which does not actually exist, seems
             as realistic as the other surrounding images. We are unaware of where the blind spot is in our day-to-
             day lives. That being so, we cannot know whether the images we obtain are all illusions. We may take
             them to be “realistic,” but this is not enough proof for believing that the images shown to us are “real.”
