Raw EEG can be found in the menu on the left-hand side of the EmotivPRO screen.

Raw EEG displays the voltage fluctuations detected from each sensor on your headset. ‌ Raw EEG graphs are displayed as uV per sample.

The channels shown include:

  • EPOC, EPOC+ and EPOC X - 14 channels are shown.

  • Insight - 5 channels are shown.

  • EPOC Flex - up to 32 channels can be shown, depending on the configuration of the headset.

The resolutions shown include:

The resolution of raw EEG for Insight, EPOC and EPOC Flex headsets is 128 Hz and 14-bits. The resolution for EPOC+ and EPOC X is 16-bits and can be either 128 or 256 Hz depending on the headset’s configuration. EPOC+ and EPOC X is 128 Hz when connected via Bluetooth.

How to turn channels on and off

So you can focus on the data you are interested in, you can turn individual channels on and off in the Raw EEG view.

To do this:

  1. ‌Click on the eye icon at the top-right hand corner of the screen.

  2. The show/hide channel pop-up box will appear.

  3. Select the channel(s) that you do not want to see.

  4. To close the pop-up box, click anywhere outside of the box.

How to toggle all channels on and off

‌You can toggle all EEG channels on and off in the Raw EEG view.

To do this:

  1. ‌Click on the eye icon at the top-right-hand corner of the screen.

  2. The show/hide channel pop-up box will appear.

  3. Click on the Toggle All button in the pop-up.

  4. To close the pop-up box, click anywhere outside of the box.

  5. To view a single-channel, deselect all channels but the channel you want to see.

How to customize EEG graph scaling

Using the controls on the left-hand side of the Raw EEG view‌, you can configure the vertical scaling of your EEG graphs. You can do this for multiple channels and single channels. Your configurations will be saved locally for the next time you use EmotivPRO.

  • Channel Spacing - Adjusts the height of the display area of a channel in the multi-channel display mode. This changes the vertical resolution of the display when more than one channel is selected.

  • Amplitude min - Single channel display only. Defines the lower limit of the value displayed in single channel display mode.

  • Amplitude max - Single channel display only. Defines the upper limit of the value displayed in single channel display mode.

  • Autoscale - Single channel display only. Automatically aligns the upper and lower limit in line with the current channel values (lower limit is +/- 100 uV).

  • High-pass filter - Removes the DC offset by applying a 0.16Hz high-pass filter and is activated by default. This filter can only be removed for single-channel display.
