10-20 EEG Placement:

10-20 EEG Placement Full Hook Up

10-20 EEG Placement:

10-20 EEG Placement Measure from nasion to the inion mark Cz at 50% mark point 10% up from nasion Fpz mark point 10% up from inion Oz Measure the distance from pre-auricular point to pre-auricular point through Cz Mark 50%. Cz is the intersection

10-20 EEG Placement:

10-20 EEG Placement Mark 10% up from each pre-auricular point. This will give you T3 (left side) T4 (right side). Mark 20% down on each side from Cz (or up from T3 and T4). This will give you C3 (left side) C4 ( right side).

10-20 EEG Placement:

10-20 EEG Placement Draw an intersecting line marking up from the nasion Fpz Measure the total circumference of the head through all the 10% marks starting and ending at Fpz. Mark 50%, Oz is located where this line and the 10% up from the inion intersect.

10-20 EEG Placement:

10-20 EEG Placement Mark 5% of the total circumference on each side of Oz and Fpz. This will mark Fp1 and Fp2 on the front and O1 and O2 on the back. Measure Fp1 to O1, through the first C3 mark. 50% of this distance is the second mark for C3. Do the same on the right side for C4.

10-20 EEG Placement:

10-20 EEG Placement The first mark for Fz is made by marking half the distance from Cz to Fpz. The first mark for Pz is made by marking half the distance from Cz to Oz. Measure the circumference of the head. The intersecting lines for T3 and T4 are found by marking half the distance from Oz to Fpz on the left and right sides.

10-20 EEG Placement:

10-20 EEG Placement F7 is found by marking half the distance from Fp1 to T3. T5 is found by marking half the distance from T3 to O1. T6 is found by marking half the distance from O2 to T4. F8 is found by marking half the distance from T4 toFp2

10-20 EEG Placement:

10-20 EEG Placement The first mark for F3 is made by marking half the distance from Fp1 to C3. The first mark for F4 is made by marking half the distance from Fp2 to C4. The first mark for P3 is made by marking half the distance from C3 to O1. The first mark for P4 is made by marking half the distance from C4 to O2.

10-20 EEG Placement:

10-20 EEG Placement Second mark for Pz is made by marking half the distance from T5 to T6. Second mark for Fz is made by marking half the distance from F7 to F8. Second mark for F3 is made by marking half the distance from F7to Fz. Second mark for F4 is made by marking half the distance from F8 to Fz.

10-20 EEG Placement:

10-20 EEG Placement Second mark for P3 is made by marking half the distance from T5 to Pz. Second mark for P4 is made by marking half the distance from T6 to Pz.
