[Phantom vision phenomenon].
The subject of the paper is the phenomenon of phantom vision. It occurs among the blind (or almost blind) and is characterised by perceiving various visual sensations, for example: light, geometrical shapes, buildings, people, flowers etc. The paper presents views explaining the generation of phantom vision. According to Melzack's theory, the occurrence of these sensations is explained in relation to the phenomenon of transforming the neuro-activity of the brain in a specific--for each organ--neuronal network called neuromatrix. Even if some organs do exist but have ceased to function completely (or to a significant degree) and consequently the brain does not receive any sensory stimuli from them, the neuromatrix in brain can generate visual sensations constituting the phantom vision phenomenon. The paper also presents three cases of phantom vision.
