The successful treatment of dyslexia is heavily involved with the visual cortex, which is at the back of the brain.![\"The](\"https:\/\/alcv.com.au\/WP\/wp-content\/uploads\/2015\/12\/ScienceExplained1-300x195.png\")
In pure medical terms, it is situated on the medial aspect of the occipital lobe in relation to the calcarine fissure. It is characterised by the\u00a0distinguishing white line or stria of Gennari, which is visible to the naked eye. The cellular structure of the visual cortex is of the highly granular type associated elsewhere in the cortex with\u00a0sensory function. The outer and inner granular layers are made up of small granular cells densely packed.<\/p>\n
A simple analogy of the visual cortex likens it to that of a Layer cake with 7 layers, the eye simply being the camera. Utilising the LASD (Lawson Anti-Suppression Device), the larger discs\u00a0stimulate the upper layers and the finest bands stimulating the deepest layer of the visual cortex.<\/p>\n
The eye is like the camera: The visual cortex in the occipital (lower back part of the brain) area is the main receiving station of the visual impulses, and the frontal lobe (upper area) of the brain interprets what is being seen.<\/p>\n
For normal vision to occur there should be steady binocular\u00a0fixation in both eyes. However, many times the fixation of one macula is very unsteady, or there can be an eccentric fixation.\u00a0Demonstrating the main cause for the learning problem, the patient is able to obtain a clear focus at any level of gaze, but it cannot be maintained.<\/p>\n
As fixation fails, so does the patient’s\u00a0concentration. As there is unsteady or\u00a0incorrect fixation, the frontal lobe of the brain lays down deep central suppression in the visual cortex (occipital cortex) of the affected eye.\u00a0\u00a0This is what we term visual dyslexia; a\u00a0physiological inability for normal vision\u00a0resulting in a learning disability.<\/p>\n","protected":false},"excerpt":{"rendered":"
