Two positions EEG
Connect the EXG Sensor TP 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 (NeXus-4 or NeXus-10)
or upward (NeXus-32).
To create one reference for both positive electrodes, use the linked ear cable.
Connect the EXG Ground TP to the Ground (Gnd) of the NeXus.
Sensors can be disconnected by pulling the silver ribbed part of the connector backward.
Place cup or ring electrodes on the EXG sensors TP and place a cup or ring electrode on to the
EXG ground TP.
Determine electrode positions according to the 10-20 system by using measuring tape and
marking positions with a skin marker.
Rub the skin with a cotton swab and Nuprep at all electrode positions. Remove remaining
gel with a tissue. As an alternative to using Nuprep, alcohol pads are sometimes used.
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.
