Introduction
This manual provides a step-by-step review of how to do EEG measurements with the
NeXus-4, NeXus-10 or NeXus-32. The manual provides information about the required
hardware, preparation and measurement steps, background information on artefacts
(appendix 1) and care of materials (appendix 2).

Required Equipment
Depending on the chosen setup, the following items are required to perform EEG
measurements:
-Nexus-4, NeXus-10 or NeXus-32
-EXG Sensor, EEG Linked Ear Sensor (2 or 4 channel), EXG TP Sensor or EEG Linked Ear
TP Sensor (2 or 4 channel)
-EXG Ground or EXG Ground TP
-EEG Discs, EEG Disc Ear Electrodes, EEG Minicap Electrodes, cup or ring electrodes*
-Nuprep
-Electrode paste (e.g. Ten20) or Electro gel
-Ear clips for EEG discs or Ear clips for EEG Minicap electrodes
-Syringe with blunt needle (for Electro gel) or scoop (for Electrode paste)
-Minicap or Microcap
-Tissues
-Cotton swabs
-Measuring tape
-Skin marker
*Ag/AgCl electrodes.

EEG measurement setup
The NeXus-4 can measure up to two positions EEG, the NeXus-10 up to 4 and the NeXus-32
up to 21 positions of EEG. Please refer to the User Guide NeXus-32 qEEG for a 21 channel cap
measurement.
NeXus-4
NeXus-10
NeXus-32
1 position EEG
2 positions EEG
4 positions EEG
21 positions EEG
Use the Internationally accepted 10-20 EEG system for EEG electrode placement, see
Appendix 1: 10-20 EEG system.
Choose an EEG measurement setup and then jump to BioTrace+ for further instructions on
software.
Before the actual measurement can start, the equipment has to be connected. Detailed information on
setting up the NeXus can be found in the NeXus User Manual or Quick Start.
