In-Ear EEG with the Muse


#1

Hi all,

I’m interested in using the Muse for in-ear EEG (see our past work, [1, 2]).

From what I gather, I can use [[6-channel streaming format][Preset AB]] to gain access to a Left Aux and Right Aux channel.
All I would need to do on the hardare end is “strip a plain old usb micro cable and connect D- (pin 2)” to an electrode ([[Question about connection of external device][source]]).

So, if I have a 2014 Muse with research firmware, I could get two additional channels - either one in each ear, or two in one ear.

Is this correct?

Iff this is correct, here are my questions:

  • Can I get any more than two additional channels? (Our earpieces can have up to 3 electrodes per ear).
  • Can I access raw voltage data from the aux channels at 500Hz, just like the other channels?
  • Are these data available via teh OSC interface (I’m using Muse lab to record OSC signals from both Muse and PsychoPy).

Thank you in advance!

Any and all other tips are welcome.

Hi there,

You can get 2 aux channels on the 2014 Muse and one on the 2016 Muse. If you need ten or more customizable electrode locations, a better option is an openBCI board.

  • Can I access raw voltage data from the aux channels at 500Hz, just like the other channels?

Yep!

  • Are these data available via teh OSC interface (I’m using Muse lab to record OSC signals from both Muse and PsychoPy).

Yep!
