As I'm not medical schooled, I don't fully understand your question I'm
afraid. I think you're talking about EEG-protocols. The only thing I ca=
tell you is there were no "giant potentials" upon lightstimulation. I've
three descriptions of EEG-protocols (in cronological way with one week
intervals, recorded one month after acute onset of the disease) :
1) Lots of delta-activity (2-3 c/s) at background-level (100-200 =B5V) an=
th=E9ta-activity (4-5 c/s) with amplitudo 'till 100 =B5V (symmetrical dif=
2) Th=E9ta-activity (6 c/s) located at the "back" of the brain (100-200 =B5=
with symmetrical pattern; at background-level there is diffuse
delta-activity (2-3 c/s) and th=E9ta-activity (4-6 c/s); no periodical
3) Delta-activity (2-3 c/s) with amplitudo of 60 =B5V and th=E9ta-activit=
c/s) with higer voltages; general "paroxysmes" with high voltage
th=E9ta-activity and multifocal epileptic peaks. =20
I hope you can do something with this.
