The NeXus EEG cap has especially been designed for the NeXus-32. It is a 32channel EEG cap according to the 10-20 system (locations are shown on the cap.) This cap does not need electrodes, since they are already part of the cap. The electrodes are sintered and therefore the cap can be used hundreds of times. The cap is of stretchy and comfortable material and comes in three sizes; small, medium and large. The rubber suction cups on the inside of the cap , keep the cap in place and make sure that no electro-gel gets dispersed. All cables are carbon coated and use our active noise cancellation technology. All cables are nicely held together.
