• Can tinnitus be measured with EEG or MEG (magnetoencephalography)?
  • Is it visible in a power spectrum?
  • In an ERP/ERF?
  • $\begingroup$ I think I've created a MEG tag, but as @ArtemKaznatcheev found, there are broader tags to use for your question. I found 8 questions involving MEG, but mostly through the answers. Yours is one of the first few questions that pertains directly to MEG. $\endgroup$ – Nick Stauner Jan 6 '14 at 23:45

Michelle Heijblom's (2009) master thesis on Visualising tinnitus with fMRI and EEG mentions the following:

Different studies report that tinnitus is characterised by an increase in slow-wave activity (0.5- 4Hz: delta activity) and a decrease in alpha activity (8-12 Hz) at temporal regions. Recently it has been suggested that this loss of alpha power is related to an increase in gamma power. [Weisz 2005, Weisz 2007, Lorenz 2009, Ashton 2007, Wienbruch 2006]. Weisz et al. state that the alpha decrease and delta increase resemble the state during slow wave sleep. This supports the idea that the changes in spontaneous brain activity might be mediated by sensory deprivation (hearing loss).
