Figure 4A: Scatterplot with regression line demonstrating the relation between the length of the track to the active electrode (in mm) in the right hemisphere and the difference score for semantic fluency (6-month score minus baseline score). The lower the number (in mm) reflects a shorter track in the right hemisphere and a lower difference score reflects a greater decline in semantic fluency performance following surgery. (p=0.01)

Figure 4B: Scatterplot with regression line demonstrating the relation between the distance (in mm) of the active electrode from the midpoint of the AC-PC line in the right hemisphere with verbal short-term memory difference scores (6-month score minus baseline score). The lower distance is in a more anterior direction while a higher distance is in a more posterior direction. A lower difference score reflects worse verbal short-term memory performance following surgery. (p=0.003)
