5. B RODMANN AREAS IN THE LEFT HEMISPHERE 04/15/11 5 SPAN 4130 - Harry Howard - Tulane University Inferior frontal gyrus (IFG) = green, Superior temporal gyrus (STG) = red Middle temporal gyrus (MTG) = blue

6. EL SISTEMA 10-20 The "10" and "20" refer to the fact that the actual distances between adjacent electrodes are either 10% or 20% of the total front-back or right-left distance of the skull. Each site has a letter to identify the lobe and a number to identify the hemisphere location. The letters F, T, C, P and O stand for Frontal, Temporal, Central, Parietal, and Occipital, respectively. Note that there exists no central lobe, the "C" letter is only used for identification purposes only. A "z" (zero) refers to an electrode placed on the midline. Even numbers (2,4,6,8) refer to electrode positions on the right hemisphere, whereas odd numbers (1,3,5,7) refer to those on the left hemisphere. Two anatomical landmarks are used for the essential positioning of the EEG electrodes: first, the nasion which is the point between the forehead and the nose; second, the inion which is the lowest point of the skull from the back of the head and is normally indicated by a prominent bump. 04/15/11 SPAN 4130 - Harry Howard - Tulane University 6
