Here's a great one. Below is adapted from: Wieser HG, 1982, Zur Frage der lokalisatorischen Bedeutung epileptischer Halluzinationen. In: Karbowski K, editor. Halluzinationen bei Epilepsien und ihre Differentialdiagnose. Bern: Verlag Hans Huber; 1982. p. 67–92. Chronically implanted electrodes in epileptic patients, when stimulated produced different types of visual effects. Stimulation at #46 (G9 in left image, D9 in right image) resulted in “snow blizzard” Other points of interest 5: rotating spirals 28, 32, 45, 59: Flicker sensation or flashes 35: white round spot surrounded by a grey ring 54, 59: diffuse colours 67: coloured stripes 70: dots 78: simple geometric patterns This is an older study (1982) that appears to support this year’s findings and is possibly a step toward treatment (maybe rTMS if the area is more pinpointed?). Can anyone access and translate this chapter?
