Neuron-Spectrum-5 and Neuron-Spectrum-6g EEG amplifiers from Neurosoft company can be paired up to increase EEG channels. It is usually necessary for invasive EEG recording or for High-density EEG.
64-78 channel solutions
Neurosoft has special solution for such needs with two Neuron-Spectrum-6g amplifiers and all accessories.
You also can combine all NS-6g series devices, not only NS-65. For example with two NS-64 you can get up to 50 EEG channel. Also you can paired NS-65 with NS-64, for example.
As for NS-5, you can use paired solution for 64 EEG channels recording (or up to 68 with Ref referent - in this case A1, A2 will be used as active electrodes).
Mount
For the mountain two device on one stand, you can use special unit for mounting two amplifiers:
For NS-5 it is necessary to order:
- Mounting plate for two amplifier units NS016221.022 (code 222752): 1 pcs.
For NS-65 it is necessary to order:
- Mounting plate for two amplifier units NS016221.070 (code 241268): 1 pcs.
Also you can use our new VESA mount for amplifiers
Connection
To use two EEG amplifiers as one device you should connect them to PC via two nearest USB-ports or via KM-7-2 USB-hub (order code: DS042.02.01.001.000).
Also for recording EEG with two amplifiers from one patient , GND and REF sockets of each amplifier should be connected to the patient. To do this you can use two different electrodes for each amplifier, but it is more convenient to use special Y-adapter to connect to amplifiers and put on the patient only one electrode for GND and one for REF.
For NS-5 it is necessary to order:
- Y-adapter NS006103.019-01 (code 241577): 2 pcs.
For NS-65 it is necessary to order:
- Y-adapter NS006103.019 (code 101694): 2 pcs.
Electrodes
For 64 and more EEG channels you can use:
- single cup electrodes (code NS245073);
- electrode caps;
- invasive EEG electrodes (grids, strips, needle).
Single cup electrode (NS245073)
Electrode cap
To order such electrode cap use this codes:
- MCS cap PROFESSIONAL 64 (code 033-3-032);
- MCS TP2KEL40F adapter (code 033-6-010).
Invasive EEG electrodes
Montages
Using EEG montage manager window you can create new montages both for scalp recording (according to "10-10%" system) and for invasive recordings. In derivation setting it is necessary to set amplifier number:
For example, to record TP7 derivation we use C4 channel of the second amplifier.
Also you can use table editor for the montage:
Recording
When amplifiers are connected, montage is created we can start new exam, put electrodes and start recording.
Conclusion
Special solution with two EEG amplifiers, connected and used as one device, can be useful for invasive EEG recordings and High-density EEG with up to 64-78 channels.
