Fig. 1

Anatomical location of the stimulation points and postoperative location of the electrodes on both surgeries. Red dots (A,B,D,E) show the position of the center of the stimulation after the first and second surgery superimposed in Mai atlas*†. a Coronal section 4,2 mm anterior to AC showing the middle point between the two active contacts on the right side after the first surgery. b Coronal section 5,8 mm anterior to AC showing the middle point between the two active contacts on the left side after the first surgery. c Postoperative CT fused with MRI showing the radiological position of the electrodes with respect to anterior comissure after the first surgery. d Coronal section 4,0 mm posterior to AC showing the middle point between the two active contacts on the right side after the second surgery. e Coronal section 2,7 mm posterior to AC showing the middle point between the two active contacts on the left side after the second surgery. f Postoperative CT fused with MRI showing radiological position of the electrodes with respect to anterior comissure after the second surgery. * Images on both sides correspond to frontal sections of left hemispheres of the human brain in Mai atlas. Frontal sections most closely related with anatomical location of the stimulation point have been chosen for the figure. † Elsevier Ltd. granted written permission to use, adapt and publish the images belonging to Atlas of the Human Brain, 3° ed (ISBN 9780123736031), Mai et al.
