Both pathways lead to the thalamus, but action potentials from the magnocellular system arrive 7-10 ms sooner (Maunsell & Gibson, 1992). A deficit in magnocellular processing has long been hypothesized to be the root cause of developmental dyslexia (e.g., Stein & Walsh, 1997).o see but not to read; the magnocellular theory of dyslexia.
