NeXus-32
Powerful all-round system

The NeXus-32 is a powerful all-around system for EEG, neurofeedback, biofeedback and psychophysiological research. It can be used with a 21 channel EEG Cap. It can measure up to 4 bipolar channels of electrophysiological signals such as EEG, EMG or ECG and it has 4 auxiliary inputs for a wide range of additional signals. It also has an input for triggers or SpO2.

It offers a total solution for qEEG, neurofeedback and biofeedback. The NeXus-32 has up to 24 inputs for unipolar EEG signals, up to 4 channels of EEG, EMG, ECG, EOG and 4 inputs for peripheral signals like heart rate, relative blood flow, skin conductance, respiration, temperature, and more. The NeXus-32 also offers has extensive interfacing options.

Reliable high-quality signals:

NeXus by Mind Media stands for clean signals by using active shielding technology and carbon-coated cables for minimal artefacts and noise. We offer a shielded EEG cap for the best signal quality and a minimum of noise.

Due to the use of sintered Ag/AgCl electrodes, we can provide the very best signal quality. Built with high-quality electronics and medical-grade technology to perform very reliable and accurate measurements and analysis.


Multimodal data acquisition:

NeXus-32 is an integrated multimodal system for measuring and training a wide variety of physiological signals simultaneously:
