What is a main aspect of the thinner fovea/macula cones?
The major aspect of the fovea/macula cones is that they all have single line pathways (one cone, one bipolar cell, and one ganglion cell) making up one-half the optic nerve. All other cones, rods, and bipolar cells “converge” into one million ganglion cell axons. What occurs at the optic chiasm, thalamus, lateral geniculate bodies? Some nerve fibers leave the optic tract at the optic chiasm where they connect with muscle nerves controlling the pupil energy response. Energy’s main path continues through the six-layered thalamus onto the lateral geniculate body where energy reorganization takes place. “Association” cells make connections, integrate, and reorder different parts and information, which is believed to be connected to the phenomenon of attention. What occurs as the single line fovea/macula pathways leave the lateral geniulate bodies? After leaving the LGB, single line fovea/macula pathways diverge 35% in the visual cortex area. This coherent energy divergence gives the fovea/
