impulses away from the neuron's cell body or soma. The impulses running from the retinal axons travel to the brain at a speed of 234 miles per hour. The impulses travelling via the optic nerve are then split at the optic chiasma and sent to the LGN (Lateral Geniculate Nuclei - on either side of the brain). The LGN is a folded sheet of neurons on each side of the brain and has six layers. Each layer receives input from only one eye. Layer 1 and 2 receive information from the M cells, and layers 3 to 6 receive information from the P cells. From the LGN, neurons project via the optic radiations to the primary visual cortex in the occipital cortex. In this area colour, form, object discrimination, complex patterns, motion and stereoscopic depth are interpreted by the brain into the images we see and take for granted every day (Rosenzweig et al, 2004) Figure 14: A Representation of Visual Nerve Pathways (V.P., 2005) 3.7.2.2 Secondary Pathways The next two visual pathways are not involved with the mechanism of sight. This includes the Retino-tectal tract and the Retino-hypothalamic tract. 66PDF Image | THE USE OF LIGHT AND COLOUR AS A HEALING MODALITY
