Hi everyone,<br>
</p>
<p style="font-family: 'Times New Roman', Times, serif; font-size: 16.3636360168457px;">

<p style="font-family: 'Times New Roman', Times, serif; font-size: 16.3636360168457px;">
I have collected data using ActiCap's 32 sensor cap and Actichamp amplifier. Data were referenced online to Tp9 (left mastoid), and saved this way. I am wondering: What is the best reference to use offline? Is it important that I use linked mastoids since
the left mastoid was used online? If so, why is this the case? I am investigating alpha asymmetry, and have read that different references can significantly shift alpha power (for example, re-referencing to linked mastoids can shift EEG power in the alpha
frequency band to right, frontal and superficial positions). For this reason, I would like to select my reference thoughtfully, and be able to defend this choice.<br>

Any suggestions/insight would be much appreciated!<br>
