Table 1: For each behavioural test, the mean and standard deviation is reported for control subjects (controls) and each of the dyslexic brain subgroups (controls, lower cerebellar declive and lower lentiform nucleus grey matter volumes than controls (LCD/LLN), lower cerebellar declive and higher lentiform nucleus grey matter volumes than controls (LCD/HLN), higher cerebellar declive and lower lentiform nucleus grey matter volumes than controls (HCD/LLN), higher cerebellar declive and higher lentiform nucleus grey matter volumes than controls (HCD/HLN)).
