The room was shielded by a faraday cage to limit line noise (60Hz power). Currently (c. Mar-May 2022) the instruments are in a room in Loeffler without a faraday cage. We can see the additional noise in data collected there at 60Hz and frequency aliases. text/html 2026-01-20T13:58:47+00:00 Anonymous (anonymous@undisclosed.example.com) Loef EEG Setup https://www.lncd.pitt.edu/wiki/doku.php?id=tools:loefeeg:setup&rev=1768917527&do=diff Loef EEG Setup Setup for EEG at Loeffler.
