I start reading the book of Sebern Fisher - Neurofeedback in the Treatment of Developmental Trauma_ Calming the Fear-Driven Brain and plan to buy some cheap neurofeedback system (openbci) for home training. For practice I need protocol from that book (also saw that protocol as Van der Kolk PTSD/Trauma Release protocol), does anyone have it or may be can create it? It available in commercial software, but this too expensive for me.
