EQUIDISTANT 61-CHANNEL-ARRANGEMENT


EQUIDISTANT 61-CHANNEL-ARRANGEMENT

Inter electrode distance 37 ± 3 mm (given a head circumference of 58 cm).

 

This montage was constructed out of triangles, which were measured on the threedimensional head surface and arrangend around Cz. The electrodes on the central line correspond to those of the 10%-system. Left and right side are symmetric. The covered area reaches down to a line from the canthus through the preauricular point to the inion.

 

The 15 grey electrodes designate a subsample (inter electrode distance approx. 75mm), that can be used for exploratory investigations.

 

Gnd and Ref in the graph are placed on the right and left cheek. Due to the modular  principle they could be placed everywhere else as well.

 

VEOG and HEOG can be computed from electrodes 50/62 and 61/51.
