-The hardware was originally in Western Psych (formally/at the time "WPIC") in Jenins office space, collaborating with Peter Bachman. Loeffler does not have a Faraday cage but the previous setup did.

 +  * Standard BESA 64 channel layout

 + 
 + 
 +==== SPA ==== 
 + 
 + 
 +  * Standard Biosemi 64 channel layout (different than Habit and 7T) 
 +  * Locations can be found from Biosemi website: [[https://www.biosemi.com/headcap.htm]] 
 +  * We did not get new channel labels so we are using the old channel labels from Habit/7T see MATLAB preprocessing code for fix 
 +  * Currently only using 61/64 channels on new SPA cap (9/23/2026)
