Two positions EEG
Connect the EXG Sensor to input A&B of the NeXus-4 or NeXus-10 and input 25&26 of the
NeXus-32. Make sure the red dot of the connector is facing downward with the NeXus-4 or
NeXus-10 or upward with the NeXus-32.
To create one reference for both positive electrodes, use the linked ear cable.
Connect the EXG Ground to the Ground (Gnd) of the NeXus.
Sensors can be disconnected by pulling the silver ribbed part of the connector backward.
Place disc electrodes on to the two red snap-ons of the EXG sensor and place a disc electrode
on to the EXG ground snap-on.
Place the two black snap-ons of the EXG sensor together with disc electrodes on to an ear
clip.
Determine electrode positions according to the 10-20 system by using measuring tape and
marking positions with a skin marker.
In a linked-ear setup, the positive electrodes are referenced to two linked negative electrodes. In order
to create a linked-ear setup, a Linked Ear cable is placed in between the EXG sensor and the input of the
Nexus. Refer to the linked ear manual for an extensive overview.
