SPHERICAL EQUIDISTANT 32-CH.-ARRANGEMENT

Inter electrode distance 53 ± 3 mm (given a head circumference of 58 cm).

This arrangement uses 32 equidistant positions out of the 124-channel montage by Gölz & Rösler, Marburg (Montage No. 14). The covered area reaches from Cz (here: Ref) down to a line from the canthi to the inion.

Equally spaced electrodes are suitable for all interpolating and localizing methods: brain mapping, dipole analysis, current source densities.
