mean and standard deviation (STD) were reported in the normally developing children (ND, n=32). Normal range was defined by mean ±2 STD of the values measured in ND group. Values indicating abnormally lateralized CST fiber counts in the affected hemisphere of individual SWS patient are bolded. The age, gender, and location of each legion were reported in the second column where F, M, FR, T, P, and O stand for female, male, frontal, temporal, parietal, and occipital lobe, respectively. Motor deficit scores 0–3 refer to severity of fine motor deficit (without gross motor abnormality), score 3 indicates (moderate) gross motor deficit.
