From: Cerebral hemorrhagic infarction was diagnosed subsequently after high-amplitude slow waves detected on processed electroencephalogram during sedation: a case report

Fig. 1

The electroencephalogram on postoperative day 7. An alpha-dominant pattern at 11 a.m. A changed into a delta-dominant pattern with high-amplitude on bilateral forehead at 4 p.m. B. Reduced amplitude with asymmetric suppressed/delta-dominant pattern detected on left forehead at 7 p.m. C. L1, R1, L2, and R2 are labels of the electrodes. L1 and R1 are affixed to the bilateral forehead above the eyebrows, and L2 and R2 are affixed to the hairless area at the upper region of the bilateral temples. The amplitude range is − 50 μV to 50 μV
