Abstract
Sensor position indicator coils to be used in magnetoencephalographic experiments and a means of attaching them to the head. The invention comprises a headband (1) and a coil assembly attached to it. The coil assembly consists of a coil set (5) and of at least three fastening strips (6) or of fastening strips having coil sets of individual coils (5') on them. The mechanical properties of the coils are very important. The coil set (5) has three thin- or thick-film coils cast in epoxy resin. The outside surface of the headband (1) and the inside surfaces of the fastening strips (6) have been covered with materials adhering to each other easily. In addition, the underside of the coil set (5) can contain three small knobs, formed during casting, on which the coil set leans when pressed against the head, staying in the tangent plane of the head.
