Family analysis 1. a, The endogenous connections present within the four-region model. All connections were tested to determine whether they were modulated by reading. Input entered the model at region iO as indicated by the black square and arrow. b, Family groups divided according to connections modulated from input source. Solid black arrows indicate the connections used to partition model space into four families and are therefore present in all models within a given family. Dashed arrows indicate connections tested within each family across models. c, Family results—graph showing the exceedance probability (xp) for each family. A, aSTS; P, pSTS.
