The percentages of patients with left-sided, right-sided or either-sided damage in hippocampi, medial temporal lobes, lateral temporal lobes, inferior frontal lobes, and dorsolateral frontal cortices is shown. Chi-squared test of independence statistics are also shown. N was determined by the number of patients with scans made available to the study researchers.
